THE MECHANISM OF DETECTION
(_Related by Christopher Jervis, M.D._)
The singular circumstances that attended the death of Mr. Oscar
Brodski, the well-known diamond merchant of Hatton Garden,
illustrated very forcibly the importance of one or two points in
medico-legal practice which Thorndyke was accustomed to insist were
not sufficiently appreciated. What those points were, I shall leave
my friend and teacher to state at the proper place; and meanwhile, as
the case is in the highest degree instructive, I shall record the
incidents in the order of their occurrence.
The dusk of an October evening was closing in as Thorndyke and I, the
sole occupants of a smoking compartment, found ourselves approaching
the little station of Ludham; and, as the train slowed down, we
peered out at the knot of country people who were waiting on the
platform. Suddenly Thorndyke exclaimed in a tone of surprise: “Why,
that is surely Boscovitch!” and almost at the same moment a brisk,
excitable little man darted at the door of our compartment and
literally tumbled in.
“I hope I don’t intrude on this learned conclave,” he said, shaking
hands genially and banging his Gladstone with impulsive violence into
the rack; “but I saw your faces at the window, and naturally jumped
at the chance of such pleasant companionship.”
“You are very flattering,” said Thorndyke; “so flattering that you
leave us nothing to say. But what in the name of fortune are you
doing at--what’s the name of the place--Ludham?”
“My brother has a little place a mile or so from here, and I have
been spending a couple of days with him,” Mr. Boscovitch explained.
“I shall change at Badsham Junction and catch the boat train for
Amsterdam. But whither are you two bound? I see you have your
mysterious little green box up on the hat-rack, so I infer that you
are on some romantic quest, eh? Going to unravel some dark and
intricate crime?”
“No,” replied Thorndyke. “We are bound for Warmington on a quite
prosaic errand. I am instructed to watch the proceedings at an
inquest there to-morrow on behalf of the Griffin Life Insurance
Office, and we are travelling down to-night as it is rather a
cross-country journey.”
“But why the box of magic?” asked Boscovitch, glancing up at the
hat-rack.
“I never go away from home without it,” answered Thorndyke. “One
never knows what may turn up; the trouble of carrying it is small
when set off against the comfort of having appliances at hand in an
emergency.”
Boscovitch continued to stare up at the little square case covered
with Willesden canvas. Presently he remarked: “I often used to wonder
what you had in it when you were down at Chelmsford in connection
with that bank murder--what an amazing case that was, by the way, and
didn’t your methods of research astonish the police!” As he still
looked up wistfully at the case, Thorndyke good-naturedly lifted it
down and unlocked it. As a matter of fact he was rather proud of his
“portable laboratory,” and certainly it was a triumph of
condensation, for, small as it was--only a foot square by four inches
deep--it contained a fairly complete outfit for a preliminary
investigation.
“Wonderful!” exclaimed Boscovitch, when the case lay open before him,
displaying its rows of little reagent bottles, tiny test-tubes,
diminutive spirit-lamp, dwarf microscope and assorted instruments on
the same Lilliputian scale; “it’s like a doll’s house--everything
looks as if it was seen through the wrong end of a telescope. But are
these tiny things really efficient? That microscope now----”
“Perfectly efficient at low and moderate magnifications,” said
Thorndyke. “It looks like a toy, but it isn’t one; the lenses are the
best that can be had. Of course a full-sized instrument would be
infinitely more convenient--but I shouldn’t have it with me, and
should have to make shift with a pocket-lens. And so with the rest of
the under-sized appliances; they are the alternative to no
appliances.”
Boscovitch pored over the case and its contents, fingering the
instruments delicately and asking questions innumerable about their
uses; indeed, his curiosity was but half appeased when, half-an-hour
later, the train began to slow down.
“By Jove!” he exclaimed, starting up and seizing his bag, “here we
are at the junction already. You change here too, don’t you?”
“Yes,” replied Thorndyke. “We take the branch train on to Warmington.”
As we stepped out onto the platform, we became aware that something
unusual was happening or had happened. All the passengers and most of
the porters and supernumeraries were gathered at one end of the
station, and all were looking intently into the darkness down the
line.
“Anything wrong?” asked Mr. Boscovitch, addressing the
station-inspector.
“Yes, sir,” the official replied; “a man has been run over by the
goods train about a mile down the line. The station master has gone
down with a stretcher to bring him in, and I expect that is his
lantern that you see coming this way.”
As we stood watching the dancing light grow momentarily brighter,
flashing fitful reflections from the burnished rails, a man came out
of the booking-office and joined the group of onlookers. He attracted
my attention, as I afterwards remembered, for two reasons: in the
first place his round, jolly face was excessively pale and bore a
strained and wild expression, and, in the second, though he stared
into the darkness with eager curiosity he asked no questions.
The swinging lantern continued to approach, and then suddenly two men
came into sight bearing a stretcher covered with a tarpaulin, through
which the shape of a human figure was dimly discernible. They
ascended the slope to the platform, and proceeded with their burden
to the lamp-room, when the inquisitive gaze of the passengers was
transferred to a porter who followed carrying a handbag and umbrella
and to the station-master who brought up the rear with his lantern.
As the porter passed, Mr. Boscovitch started forward with sudden
excitement.
“Is that his umbrella?” he asked.
“Yes, sir,” answered the porter, stopping and holding it out for the
speaker’s inspection.
“My God!” ejaculated Boscovitch; then, turning sharply to Thorndyke,
he exclaimed: “That’s Brodski’s umbrella. I could swear to it. You
remember Brodski?”
Thorndyke nodded, and Boscovitch, turning once more to the porter,
said: “I identify that umbrella. It belongs to a gentleman named
Brodski. If you look in his hat, you will see his name written in it.
He always writes his name in his hat.”
“We haven’t found his hat yet,” said the porter; “but here is the
station-master.” He turned to his superior and announced: “This
gentleman, sir, has identified the umbrella.”
“Oh,” said the station-master, “you recognize the umbrella, sir, do
you? Then perhaps you would step into the lamp-room and see if you
can identify the body.”
Mr. Boscovitch recoiled with a look of alarm. “Is it--is he--very
much injured?” he asked nervously.
“Well, yes,” was the reply. “You see, the engine and six of the
trucks went over him before they could stop the train. Took his head
clean off, in fact.”
“Shocking! shocking!” gasped Boscovitch. “I think--if you don’t
mind--I’d--I’d rather not. You don’t think it necessary, doctor, do
you?”
“Yes, I do,” replied Thorndyke. “Early identification may be of the
first importance.”
“Then I suppose I must,” said Boscovitch; and, with extreme
reluctance, he followed the station-master to the lamp-room, as the
loud ringing of the bell announced the approach of the boat train.
His inspection must have been of the briefest, for, in a few moments,
he burst out, pale and awe-stricken, and rushed up to Thorndyke.
“It is!” he exclaimed breathlessly. “It’s Brodski! Poor old Brodski!
Horrible! horrible! He was to have met me here and come on with me to
Amsterdam.”
“Had he any--merchandize about him?” Thorndyke asked; and, as he
spoke, the stranger whom I had previously noticed edged up closer as
if to catch the reply.
“He had some stones, no doubt,” answered Boscovitch, “but I don’t
know what they were. His clerk will know, of course. By the way,
doctor, could you watch the case for me? Just to be sure it was
really an accident or--you know what. We were old friends, you know,
fellow townsmen, too; we were both born in Warsaw. I’d like you to
give an eye to the case.”
“Very well,” said Thorndyke. “I will satisfy myself that there is
nothing more than appears, and let you have a report. Will that do?”
“Thank you,” said Boscovitch. “It’s excessively good of you, doctor.
Ah, here comes the train. I hope it won’t inconvenience you to stay
and see to the matter.”
“Not in the least,” replied Thorndyke. “We are not due at Warmington
until tomorrow afternoon, and I expect we can find out all that is
necessary to know and still keep our appointment.”
As Thorndyke spoke, the stranger, who had kept close to us with the
evident purpose of hearing what was said, bestowed on him a very
curious and attentive look; and it was only when the train had
actually come to rest by the platform that he hurried away to find a
compartment.
No sooner had the train left the station than Thorndyke sought out
the station-master and informed him of the instructions that he had
received from Boscovitch. “Of course,” he added, in conclusion, “we
must not move in the matter until the police arrive. I suppose they
have been informed?”
“Yes,” replied the station-master; “I sent a message at once to the
Chief Constable, and I expect him or an inspector at any moment. In
fact, I think I will slip out to the approach and see if he is
coming.” He evidently wished to have a word in private with the
police officer before committing himself to any statement.
As the official departed, Thorndyke and I began to pace the now empty
platform, and my friend, as was his wont, when entering on a new
inquiry, meditatively reviewed the features of the problem.
“In a case of this kind,” he remarked, “we have to decide on one of
three possible explanations: accident, suicide or homicide; and our
decision will be determined by inferences from three sets of facts:
first, the general facts of the case; second, the special data
obtained by examination of the body, and, third, the special data
obtained by examining the spot on which the body was found. Now the
only general facts at present in our possession are that the deceased
was a diamond merchant making a journey for a specific purpose and
probably having on his person property of small bulk and great value.
These facts are somewhat against the hypothesis of suicide and
somewhat favourable to that of homicide. Facts relevant to the
question of accident would be the existence or otherwise of a level
crossing, a road or path leading to the line, an enclosing fence with
or without a gate, and any other facts rendering probable or
otherwise the accidental presence of the deceased at the spot where
the body was found. As we do not possess these facts, it is desirable
that we extend our knowledge.”
“Why not put a few discreet questions to the porter who brought in
the bag and umbrella?” I suggested. “He is at this moment in earnest
conversation with the ticket collector and would, no doubt, be glad
of a new listener.”
“An excellent suggestion, Jervis,” answered Thorndyke. “Let us see
what he has to tell us.” We approached the porter and found him, as I
had anticipated, bursting to unburden himself of the tragic story.
“The way the thing happened, sir, was this,” he said, in answer to
Thorndyke’s question: “There’s a sharpish bend in the road just at
that place, and the goods train was just rounding the curve when the
driver suddenly caught sight of something lying across the rails. As
the engine turned, the headlights shone on it and then he saw it was
a man. He shut off steam at once, blew his whistle, and put the
brakes down hard, but, as you know, sir, a goods train takes some
stopping; before they could bring her up, the engine and half-a-dozen
trucks had gone over the poor beggar.”
“Could the driver see how the man was lying?” Thorndyke asked.
“Yes, he could see him quite plain, because the head lights were full
on him. He was lying on his face with his neck over the near rail on
the down side. His head was in the four-foot and his body by the side
of the track. It looked as if he had laid himself out a-purpose.”
“Is there a level crossing thereabouts?” asked Thorndyke.
“No, sir. No crossing, no road, no path, no nothing,” said the
porter, ruthlessly sacrificing grammar to emphasis. “He must have
come across the fields and climbed over the fence to get onto the
permanent way. Deliberate suicide is what it looks like.”
“How did you learn all this?” Thorndyke inquired.
“Why, the driver, you see, sir, when him and his mate had lifted the
body off the track, went on to the next signal box and sent in his
report by telegram. The station-master told me all about it as we
walked down the line.”
Thorndyke thanked the man for his information, and, as we strolled
back towards the lamp-room, discussed the bearing of these new facts.
“Our friend is unquestionably right in one respect,” he said; “this
was not an accident. The man might, if he were near-sighted, deaf or
stupid, have climbed over the fence and got knocked down by the
train. But his position, lying across the rails, can only be
explained by one of two hypotheses: either it was, as the porter
says, deliberate suicide, or else the man was already dead or
insensible. We must leave it at that until we have seen the body,
that is, if the police will allow us to see it. But here comes the
station-master and an officer with him. Let us hear what they have to
say.”
The two officials had evidently made up their minds to decline any
outside assistance. The divisional surgeon would make the necessary
examination, and information could be obtained through the usual
channels. The production of Thorndyke’s card, however, somewhat
altered the situation. The police inspector hummed and hawed
irresolutely, with the card in his hand, but finally agreed to allow
us to view the body, and we entered the lamp-room together, the
station-master leading the way to turn up the gas.
The stretcher stood on the floor by one wall, its grim burden still
hidden by the tarpaulin, and the hand-bag and umbrella lay on a large
box, together with the battered frame of a pair of spectacles from
which the glasses had fallen out.
“Were these spectacles found by the body?” Thorndyke inquired.
“Yes,” replied the station-master. “They were close to the head and
the glass was scattered about on the ballast.”
Thorndyke made a note in his pocket-book, and then, as he inspector
removed the tarpaulin, he glanced down on the corpse, lying limply on
the stretcher and looking grotesquely horrible with its displaced
head and distorted limbs. For fully a minute he remained silently
stooping over the uncanny object, on which the inspector was now
throwing the light of a large lantern; then he stood up and said
quietly to me: “I think we can eliminate two out of the three
hypotheses.”
The inspector looked at him quickly, and was about to ask a question,
when his attention was diverted by the travelling-case which
Thorndyke had laid on a shelf and now opened to abstract a couple of
pairs of dissecting forceps.
“We’ve no authority to make a _post mortem_, you know,” said the
inspector.
“No, of course not,” said Thorndyke. “I am merely going to look into
the mouth.” With one pair of forceps he turned back the lip and,
having scrutinized its inner surface, closely examined the teeth.
“May I trouble you for your lens, Jervis?” he said; and, as I handed
him my doublet ready opened, the inspector brought the lantern close
to the dead face and leaned forward eagerly. In his usual systematic
fashion, Thorndyke slowly passed the lens along the whole range of
sharp, uneven teeth, and then, bringing it back to the centre,
examined with more minuteness the upper incisors. At length, very
delicately, he picked out with his forceps some minute object from
between two of the upper front teeth and held it in the focus of the
lens. Anticipating his next move, I took a labelled microscope-slide
from the case and handed it to him together with a dissecting needle,
and, as he transferred the object to the slide and spread it out with
the needle, I set up the little microscope on the shelf.
“A drop of Farrant and a cover-glass, please, Jervis,” said Thorndyke.
I handed him the bottle, and, when he had let a drop of the mounting
fluid fall gently on the object and put on the cover-slip, he placed
the slide on the stage of the microscope and examined it attentively.
Happening to glance at the inspector, I observed on his countenance a
faint grin, which he politely strove to suppress when he caught my
eye.
“I was thinking, sir,” he said apologetically, “that it’s a bit off
the track to be finding out what he had for dinner. He didn’t die of
unwholesome feeding.”
Thorndyke looked up with a smile. “It doesn’t do, inspector, to
assume that anything is off the track in an inquiry of this kind.
Every fact must have some significance, you know.”
“I don’t see any significance in the diet of a man who has had his
head cut off,” the inspector rejoined defiantly.
“Don’t you?” said Thorndyke. “Is there no interest attaching to the
last meal of a man who has met a violent death? These crumbs, for
instance, that are scattered over the dead man’s waistcoat. Can we
learn nothing from them?”
“I don’t see what you can learn,” was the dogged rejoinder.
Thorndyke picked off the crumbs, one by one, with his forceps, and
having deposited them on a slide, inspected them, first with the lens
and then through the microscope.
“I learn,” said he, “that shortly before his death, the deceased
partook of some kind of whole-meal biscuits, apparently composed
partly of oatmeal.”
“I call that nothing,” said the inspector. “The question that we have
got to settle is not what refreshments had the deceased been taking,
but what was the cause of his death: did he commit suicide? was he
killed by accident? or was there any foul play?”
“I beg your pardon,” said Thorndyke, “the questions that remain to be
settled are, who killed the deceased and with what motive? The others
are already answered as far as I am concerned.”
The inspector stared in sheer amazement not unmixed with incredulity.
“You haven’t been long coming to a conclusion, sir,” he said.
“No, it was a pretty obvious case of murder,” said Thorndyke. “As to
the motive, the deceased was a diamond merchant and is believed to
have had a quantity of stones about his person. I should suggest that
you search the body.”
The inspector gave vent to an exclamation of disgust. “I see,” he
said. “It was just a guess on your part. The dead man was a diamond
merchant and had valuable property about him; therefore he was
murdered.” He drew himself up, and, regarding Thorndyke with stern
reproach, added: “But you must understand, sir, that this is a
judicial inquiry, not a prize competition in a penny paper. And, as
to searching the body, why, that is what I principally came for.” He
ostentatiously turned his back on us and proceeded systematically to
turn out the dead man’s pockets, laying the articles, as he removed
them, on the box by the side of the hand-bag and umbrella.
While he was thus occupied, Thorndyke looked over the body generally,
paying special attention to the soles of the boots, which, to the
inspector’s undissembled amusement, he very thoroughly examined with
the lens.
“I should have thought, sir, that his feet were large enough to be
seen with the naked eye,” was his comment; “but perhaps,” he added,
with a sly glance at the station master, “you’re a little
near-sighted.”
Thorndyke chuckled good-humouredly, and, while the officer continued
his search, he looked over the articles that had already been laid on
the box. The purse and pocket book he naturally left for the
inspector to open, but the reading-glasses, pocket-knife and
card-case and other small pocket articles were subjected to a
searching scrutiny. The inspector watched him out of the corner of
his eye with furtive amusement; saw him hold up the glasses to the
light to estimate their refractive power, peer into the tobacco
pouch, open the cigarette book and examine the watermark of the
paper, and even inspect the contents of the silver match-box.
“What might you have expected to find in his tobacco pouch?” the
officer asked, laying down a bunch of keys from the dead man’s pocket.
“Tobacco,” Thorndyke replied stolidly; “but I did not expect to find
fine-cut Latakia. I don’t remember ever having seen pure Latakia
smoked in cigarettes.”
“You do take an interest in things, sir,” said the inspector, with a
side glance at the stolid station-master.
“I do,” Thorndyke agreed; “and I note that there are no diamonds
among this collection.”
“No, and we don’t know that he had any about him; but there’s a gold
watch and chain, a diamond scarf-pin, and a purse containing”--he
opened it and tipped out its contents into his hand--“twelve pounds
in gold. That doesn’t look much like robbery, does it? What do you
say to the murder theory now?”
“My opinion is unchanged,” said Thorndyke, “and I should like to
examine the spot where the body was found. Has the engine been
inspected?” he added, addressing the station-master.
“I telegraphed to Bradfield to have it examined,” the official
answered. “The report has probably come in by now. I’d better see
before we start down the line.”
We emerged from the lamp-room and, at the door, found the
station-inspector waiting with a telegram. He handed it to the
station-master, who read it aloud.
“The engine has been carefully examined by me. I find small smear of
blood on near leading wheel and smaller one on next wheel following.
No other marks.” He glanced questioningly at Thorndyke, who nodded
and remarked: “It will be interesting to see if the line tells the
same tale.”
The station-master looked puzzled and was apparently about to ask for
an explanation; but the inspector, who had carefully pocketed the
dead man’s property, was impatient to start and, accordingly, when
Thorndyke had repacked his case and had, at his own request, been
furnished with a lantern, we set off down the permanent way,
Thorndyke carrying the light and I the indispensable green case.
“I am a little in the dark about this affair,” I said, when we had
allowed the two officials to draw ahead out of ear shot; “you came to
a conclusion remarkably quickly. What was it that so immediately
determined the opinion of murder as against suicide?”
“It was a small matter but very conclusive,” replied Thorndyke. “You
noticed a small scalp-wound above the left temple? It was a glancing
wound, and might easily have been made by the engine. But--the wound
had bled; and it had bled for an appreciable time. There were two
streams of blood from it, and in both the blood was firmly clotted
and partially dried. But the man had been decapitated; and this
wound, if inflicted by the engine, must have been made after the
decapitation, since it was on the side most distant from the engine
as it approached. Now, a decapitated head does not bleed. Therefore,
this wound was inflicted before the decapitation.
“But not only had the wound bled: the blood had trickled down in two
streams at right angles to one another. First, in the order of time
as shown by the appearance of the stream, it had trickled down the
side of the face and dropped on the collar. The second stream ran
from the wound to the back of the head. Now, you know, Jervis, there
are no exceptions to the law of gravity. If the blood ran down the
face towards the chin, the face must have been upright at the time;
and if the blood trickled from the front to the back of the head, the
head must have been horizontal and face upwards. But the man when he
was seen by the engine driver, was lying _face downwards_. The only
possible inference is that when the wound was inflicted, the man was
in the upright position--standing or sitting; and that subsequently,
and while he was still alive, he lay on his back for a sufficiently
long time for the blood to have trickled to the back of his head.”
“I see. I was a duffer not to have reasoned this out for myself,” I
remarked contritely.
“Quick observation and rapid inference come by practice,” replied
Thorndyke. “What did you notice about the face?”
“I thought there was a strong suggestion of asphyxia.”
“Undoubtedly,” said Thorndyke. “It was the face of a suffocated man.
You must have noticed, too, that the tongue was very distinctly
swollen and that on the inside of the upper lip were deep
indentations made by the teeth, as well as one or two slight wounds,
obviously caused by heavy pressure on the mouth. And now observe how
completely these facts and inferences agree with those from the scalp
wound. If we knew that the deceased had received a blow on the head,
had struggled with his assailant and been finally borne down and
suffocated, we should look for precisely those signs which we have
found.”
“By the way, what was it that you found wedged between the teeth? I
did not get a chance to look through the microscope.”
“Ah!” said Thorndyke, “there we not only get confirmation, but we
carry our inferences a stage further. The object was a little tuft of
some textile fabric. Under the microscope I found it to consist of
several different fibres, differently dyed. The bulk of it consisted
of wool fibres dyed crimson, but there were also cotton fibres dyed
blue and a few which looked like jute, dyed yellow. It was obviously
a parti-coloured fabric and might have been part of a woman’s dress,
though the presence of the jute is much more suggestive of a curtain
or rug of inferior quality.”
“And its importance?”
“Is that, if it is not part of an article of clothing, then it must
have come from an article of furniture, and furniture suggests a
habitation.”
“That doesn’t seem very conclusive,” I objected.
“It is not; but it is valuable corroboration.”
“Of what?”
“Of the suggestion offered by the soles of the dead man’s boots. I
examined them most minutely and could find no trace of sand, gravel
or earth, in spite of the fact that he must have crossed fields and
rough land to reach the place where he was found. What I did find was
fine tobacco ash, a charred mark as if a cigar or cigarette had been
trodden on, Several crumbs of biscuit, and, on a projecting brad,
some coloured fibres, apparently from a carpet. The manifest
suggestion is that the man was killed in a house with a carpeted
floor, and carried from thence to the railway.”
I was silent for some moments. Well as I knew Thorndyke, I was
completely taken by surprise; a sensation, indeed, that I experienced
anew every time that I accompanied him on one of his investigations.
His marvellous power of co-ordinating apparently insignificant facts,
of arranging them into an ordered sequence and making them tell a
coherent story, was a phenomenon that I never got used to; every
exhibition of it astonished me afresh.
“If your inferences are correct,” I said, “the problem is practically
solved. There must be abundant traces inside the house. The only
question is, which house is it?”
“Quite so,” replied Thorndyke; “that is the question, and a very
difficult question it is. A glance at that interior would doubtless
clear up the whole mystery. But how are we to get that glance? We
cannot enter houses speculatively to see if they present traces of a
murder. At present, our clue breaks off abruptly. The other end of it
is in some unknown house, and, if we cannot join up the two ends, our
problem remains unsolved. For the question is, you remember, Who
killed Oscar Brodski?”
“Then what do you propose to do?” I asked.
“The next stage of the inquiry is to connect some particular house
with this crime. To that end, I can only gather up all available
facts and consider each in all its possible bearings. If I cannot
establish any such connection, then the inquiry will have failed and
we shall have to make a fresh start--say, at Amsterdam, if it turns
out that Brodski really had diamonds on his person, as I have no
doubt he had.” Here our conversation was interrupted by our arrival
at the spot where the body had been found. The station-master had
halted, and he and the inspector were now examining the near rail by
the light of their lanterns.
“There’s remarkably little blood about,” said the former. “I’ve seen
a good many accidents of this kind and there has always been a lot of
blood, both on the engine and on the road. It’s very curious.”
Thorndyke glanced at the rail with but slight attention: that
question had ceased to interest him. But the light of his lantern
flashed onto the ground at the side of the track--a loose, gravelly
soil mixed with fragments of chalk--and from thence to the soles of
the inspector’s boots, which were displayed as he knelt by the rail.
“You observe, Jervis?” he said in a low voice, and I nodded. The
inspector’s boot-soles were covered with adherent particles of gravel
and conspicuously marked by the chalk on which he had trodden.
“You haven’t found the hat, I suppose?” Thorndyke asked, stooping to
pick up a short piece of string that lay on the ground at the side of
the track.
“No,” replied the inspector, “but it can’t be far off. You seem to
have found another clue, sir,” he added, with a grin, glancing at the
piece of string.
“Who knows,” said Thorndyke. “A short end of white twine with a green
strand in it. It may tell us something later. At any rate we’ll keep
it,” and, taking from his pocket a small tin box containing, among
other things, a number of seed envelopes, he slipped the string into
one of the latter and scribbled a note in pencil on the outside. The
inspector watched his proceedings with an indulgent smile, and then
returned to his examination of the track, in which Thorndyke now
joined.
“I suppose the poor chap was near-sighted,” the officer remarked,
indicating the remains of the shattered spectacles; “that might
account for his having strayed onto the line.”
“Possibly,” said Thorndyke. He had already noticed the fragments
scattered over a sleeper and the adjacent ballast, and now once more
produced his “collecting-box,” from which he took another seed
envelope. “Would you hand me a pair of forceps, Jervis,” he said;
“and perhaps you wouldn’t mind taking a pair yourself and helping me
to gather up these fragments.”
As I complied, the inspector looked up curiously.
“There isn’t any doubt that these spectacles belonged to the
deceased, is there?” he asked. “He certainly wore spectacles, for I
saw the mark on his nose.”
“Still, there is no harm in verifying the fact,” said Thorndyke, and
he added to me in a lower tone, “Pick up every particle you can find,
Jervis. It may be most important.”
“I don’t quite see how,” I said, groping amongst the shingle by the
light of the lantern in search of the tiny splinters of glass.
“Don’t you?” returned Thorndyke. “Well, look at these fragments; some
of them are a fair size, but many of these on the sleeper are mere
grains. And consider their number. Obviously, the condition of the
glass does not agree with the circumstances in which we find it.
These are thick con cave spectacle-lenses broken into a great number
of minute fragments. Now how were they broken? Not merely by falling,
evidently: such a lens, when it is dropped, breaks into a small
number of large pieces. Nor were they broken by the wheel passing
over them, for they would then have been reduced to fine powder, and
that powder would have been visible on the rail, which it is not. The
spectacle frames, you may remember, presented the same incongruity:
they were battered and damaged more than they would have been by
falling, but not nearly so much as they would have been if the wheel
had passed over them.”
“What do you suggest, then?” I asked.
“The appearances suggest that the spectacles had been trodden on.
But, if the body was carried here the probability is that the
spectacles were carried here too, and that they were then already
broken; for it is more likely that they were trodden on during the
struggle than that the murderer trod on them after bringing them
here. Hence the importance of picking up every fragment.”
“But why?” I inquired, rather foolishly, I must admit.
“Because, if, when we have picked up every fragment that we can find,
there still remains missing a larger portion of the lenses than we
could reasonably expect, that would tend to support our hypothesis
and we might find the missing remainder elsewhere. If, on the other
hand, we find as much of the lenses as we could expect to find, we
must conclude that they were broken on this spot.”
While we were conducting our search, the two officials were circling
around with their lanterns in quest of the missing hat; and, when we
had at length picked up the last fragment, and a careful search, even
aided by a lens, failed to reveal any other, we could see their
lanterns moving, like will-o’-the-wisps, some distance down the line.
“We may as well see what we have got before our friends come back,”
said Thorndyke, glancing at the twinkling lights. “Lay the case down
on the grass by the fence; it will serve for a table.”
I did so, and Thorndyke, taking a letter from his pocket, opened it,
spread it out flat on the case, securing it with a couple of heavy
stones, although the night was quite calm. Then he tipped the
contents of the seed envelope out on the paper, and carefully
spreading out the pieces of glass, looked at them for some moments in
silence. And, as he looked, there stole over his face a very curious
expression; with sudden eagerness he began picking out the large
fragments and laying them on two visiting-cards which he had taken
from his card-case. Rapidly and with wonderful deftness he fitted the
pieces together, and, as the reconstituted lenses began gradually to
take shape on their cards I looked on with growing excitement, for
something in my colleague’s manner told me that we were on the verge
of a discovery.
At length the two ovals of glass lay on their respective cards,
complete save for one or two small gaps; and the little heap that
remained consisted of fragments so minute as to render further
reconstruction impossible. Then Thorndyke leaned back and laughed
softly.
“This is certainly an unlooked-for result,” said he.
“What is?” I asked.
“Don’t you see, my dear fellow? _There’s too much glass._ We have
almost completely built up the broken lenses, and the fragments that
are left over are considerably more than are required to fill up the
gaps.”
I looked at the little heap of small fragments and saw at once that
it was as he had said. There was a surplus of small pieces.
“This is very extraordinary,” I said. “What do you think can be the
explanation?”
“The fragments will probably tell us,” he replied, “if we ask them
intelligently.”
He lifted the paper and the two cards carefully onto the ground, and,
opening the case, took out the little microscope, to which he fitted
the lowest-power objective and eye-piece--having a combined
magnification of only ten diameters. Then he transferred the minute
fragments of glass to a slide, and, having arranged the lantern as a
microscope-lamp, commenced his examination.
“Hal” he exclaimed presently. “The plot thickens. There is too much
glass and yet too little; that is to say, there are only one or two
fragments here that belong to the spectacles; not nearly enough to
complete the building up of the lenses. The remainder consists of a
soft, uneven, moulded glass, easily distinguished from the clear,
hard optical glass. These foreign fragments are all curved, as if
they had formed part of a cylinder, and are, I should say, portions
of a wine-glass or tumbler.” He moved the slide once or twice, and
then continued: “We are in luck, Jervis. Here is a fragment with two
little diverging lines etched on it, evidently the points of an
eight-rayed star--and here is another with three points--the ends of
three rays. This enables us to reconstruct the vessel perfectly. It
was a clear, thin glass--probably a tumbler--decorated with scattered
stars; I dare say you know the pattern. Sometimes there is an
ornamented band in addition, but generally the stars form the only
decoration. Have a look at the specimen.”
I had just applied my eye to the microscope when the station-master
and the inspector came up. Our appearance, seated on the ground with
the microscope between us, was too much for the police officer’s
gravity, and he laughed long and joyously.
“You must excuse me, gentlemen,” he said apologetically, “but really,
you know, to an old hand, like myself, it does look a
little--well--you understand--I dare say a microscope is a very
interesting and amusing thing, but it doesn’t get you much forrader
in a case like this, does it?”
“Perhaps not,” replied Thorndyke. “By the way, where did you find the
hat, after all?”
“We haven’t found it,” the inspector replied.
“Then we must help you to continue the search,” said Thorndyke. “If
you will wait a few moments, we will come with you.” He poured a few
drops of xylol balsam on the cards to fix the reconstituted lenses to
their supports and then, packing them and the microscope in the case,
announced that he was ready to start.
“Is there any village or hamlet near?” he asked the station-master.
“None nearer than Corfield. That is about half-a-mile from here.”
“And where is the nearest road?”
“There is a half-made road that runs past a house about three hundred
yards from here. It belonged to a building estate that was never
built. There is a footpath from it to the station.”
“Are there any other houses near?”
“No. That is the only house for half-a-mile round, and there is no
other road near here.”
“Then the probability is that Brodski approached the rail way from
that direction, as he was found on that side of the permanent way.”
The inspector agreeing with this view, we all set off slowly towards
the house, piloted by the station-master and searching the ground as
we went. The waste land over which we passed was covered with patches
of docks and nettles, through each of which the inspector kicked his
way, searching with feet and lantern for the missing hat. A walk of
three hundred yards brought us to a low wall enclosing a garden,
beyond which we could see a small house; and here we halted while the
inspector waded into a large bed of nettles beside the wall and
kicked vigorously. Suddenly there came a clinking sound mingled with
objurgations, and the inspector hopped out holding one foot and
soliloquizing profanely.
“I wonder what sort of a fool put a thing like that into a bed of
nettles!” he exclaimed, stroking the injured foot. Thorndyke picked
the object up and held it in the light of the lantern, displaying a
piece of three-quarter inch rolled iron bar about a foot long. “It
doesn’t seem to have been here very long,” he observed, examining it
closely, “there is hardly any rust on it.”
“It has been there long enough for me,” growled the inspector, “and
I’d like to bang it on the head of the blighter that put it there.”
Callously indifferent to the inspector’s sufferings, Thorndyke
continued calmly to examine the bar. At length, resting his lantern
on the wall, he produced his pocket-lens, with which he resumed his
investigation, a proceeding that so exasperated the inspector that
that afflicted official limped off in dudgeon, followed by the
station-master, and we heard him, presently, rapping at the front
door of the house.
“Give me a slide, Jervis, with a drop of Farrant on it,” said
Thorndyke. “There are some fibres sticking to this bar.”
I prepared the slide, and, having handed it to him together with a
cover-glass, a pair of forceps and a needle, set up the microscope on
the wall.
“I’m sorry for the inspector,” Thorndyke remarked, with his eye
applied to the little instrument, “but that was a lucky kick for us.
Just take a look at the specimen.”
I did so, and, having moved the slide about until I had seen the
whole of the object, I gave my opinion. “Red wool fibres, blue cotton
fibres and some yellow vegetable fibres that look like jute.”
“Yes,” said Thorndyke; “the same combination of fibres as that which
we found on the dead man’s teeth and probably from the same source.
This bar has probably been wiped on that very curtain or rug with
which poor Brodski was stifled. We will place it on the wall for
future reference, and meanwhile, by hook or by crook, we must get
into that house. This is much too plain a hint to be disregarded.”
Hastily repacking the case, we hurried to the front of the house,
where we found the two officials looking rather vaguely up the unmade
road.
“There’s a light in the house,” said the inspector, “but there’s no
one at home. I have knocked a dozen times and got no answer. And I
don’t see what we are hanging about here for at all. The hat is
probably close to where the body was found, and we shall find it in
the morning.”
Thorndyke made no reply, but, entering the garden, stepped up the
path, and having knocked gently at the door, stooped and listened
attentively at the keyhole.
“I tell you there’s no one in the house, sir,” said the inspector
irritably; and, as Thorndyke continued to listen, he walked away,
muttering angrily. As soon as he was gone, Thorndyke flashed his
lantern over the door, the threshold, the path and the small
flower-beds; and, from one of the latter, I presently saw him stoop
and pick something up.
“Here is a highly instructive object, Jervis,” he said, coming out to
the gate, and displaying a cigarette of which only half-an-inch had
been smoked.
“How instructive?” I asked. “What do you learn from it?”
“Many things,” he replied. “It has been lit and thrown away unsmoked;
that indicates a sudden change of purpose. It was thrown away at the
entrance to the house, almost certainly by some one entering it. That
person was probably a stranger, or he would have taken it in with
him. But he had not expected to enter the house, or he would not have
lit it. These are the general suggestions; now as to the particular
ones. The paper of the cigarette is of the kind known as the
‘Zig-Zag’ brand; the very conspicuous watermark is quite easy to see.
Now Brodski’s cigarette book was a ‘Zig-Zag’ book--so called from the
way in which the papers pull out. But let us see what the tobacco is
like.” With a pin from his coat, he hooked out from the unburned end
a wisp of dark, dirty brown tobacco, which he held out for my
inspection.
“Fine-cut Latakia,” I pronounced, without hesitation.
“Very well,” said Thorndyke. “Here is a cigarette made of an unusual
tobacco similar to that in Brodski’s pouch and wrapped in an unusual
paper similar to those in Brodski’s cigarette book. With due regard
to the fourth rule of the syllogism, I suggest that this cigarette
was made by Oscar Brodski. But, nevertheless, we will look for
corroborative detail.”
“What is that?” I asked.
“You may have noticed that Brodski’s match-box contained round wooden
vestas--which are also rather unusual. As he must have lighted the
cigarette within a few steps of the gate, we ought to be able to find
the match with which he lighted it. Let us try up the road in the
direction from which he would probably have approached.”
We walked very slowly up the road, searching the ground with the
lantern, and we had hardly gone a dozen paces when I espied a match
lying on the rough path and eagerly picked it up. It was a round
wooden vesta.
Thorndyke examined it with interest and having deposited it, with the
cigarette, in his “collecting-box,” turned to retrace his steps.
“There is now, Jervis, no reasonable doubt that Brodski was murdered
in that house. We have succeeded in connecting that house with the
crime, and now we have got to force an entrance and join up the other
clues.” We walked quickly back to the rear of the premises, where we
found the inspector conversing disconsolately with the station-master.
“I think, sir,” said the former, “we had better go back now; in fact,
I don’t see what we came here for, but--here! I say, sir, you mustn’t
do that!” For Thorndyke, without a word of warning, had sprung up
lightly and thrown one of his long legs over the wall.
“I can’t allow you to enter private premises, sir,” continued the
inspector; but Thorndyke quietly dropped down on the inside and
turned to face the officer over the wall.
“Now, listen to me, inspector,” said he. “I have good reasons for
believing that the dead man, Brodski, has been in this house, in
fact, I am prepared to swear an information to that effect. But time
is precious; we must follow the scent while it is hot. And I am not
proposing to break into the house off-hand. I merely wish to examine
the dust-bin.”
“The dust-bin!” gasped the inspector. “Well, you really are a most
extraordinary gentleman! What do you expect to find in the dust-bin?”
“I am looking for a broken tumbler or wine-glass. It is a thin glass
vessel decorated with a pattern of small, eight pointed stars. It may
be in the dust-bin or it may be inside the house.”
The inspector hesitated, but Thorndyke’s confident manner had
evidently impressed him.
“We can soon see what is in the dust-bin,” he said, “though what in
creation a broken tumbler has to do with the case is more than I can
understand. However, here goes.” He sprang up onto the wall, and, as
he dropped down into the garden, the station-master and I followed.
Thorndyke lingered a few moments by the gate examining the ground,
while the two officials hurried up the path. Finding nothing of
interest, however, he walked towards the house, looking keenly about
him as he went; but we were hardly half-way up the path when we heard
the voice of the inspector calling excitedly.
“Here you are, sir, this way,” he sang out, and, as we hurried
forward, we suddenly came on the two officials standing over a small
rubbish-heap and looking the picture of astonishment. The glare of
their lanterns illuminated the heap, and showed us the scattered
fragments of a thin glass, star-pattern tumbler.
“I can’t imagine how you guessed it was here, sir,” said the
inspector, with a new-born respect in his tone, “nor what you’re
going to do with it now you have found it.”
“It is merely another link in the chain of evidence,” said Thorndyke,
taking a pair of forceps from the case and stooping over the heap.
“Perhaps we shall find something else.” He picked up several small
fragments of glass, looked at them closely and dropped them again.
Suddenly his eye caught a small splinter at the base of the heap.
Seizing it with the forceps, he held it close to his eye in the
strong lamplight, and, taking out his lens, examined it with minute
attention. “Yes,” he said at length, “this is what I was looking for.
Let me have those two cards, Jervis.”
I produced the two visiting-cards with the reconstructed lenses stuck
to them, and, laying them on the lid of the case, threw the light of
the lantern on them. Thorndyke looked at them intently for some time,
and from them to the fragment that he held. Then, turning to the
inspector, he said: “You saw me pick up this splinter of glass?”
“Yes, sir,” replied the officer.
“And you saw where we found these spectacle-glasses and know whose
they were?”
“Yes, sir. They are the dead man’s spectacles, and you found them
where the body had been.”
“Very well,” said Thorndyke; “now observe;” and, as the two officials
craned forward with parted lips, he laid the little splinter in a gap
in one of the lenses and then gave it a gentle push forward, when it
occupied the gap perfectly, joining edge to edge with the adjacent
fragments and rendering that portion of the lens complete.
“My God!” exclaimed the inspector. “How on earth did you know?”
“I must explain that later,” said Thorndyke. “Meanwhile we had better
have a look inside the house. I expect to find there a cigarette--or
possibly a cigar--which has been trodden on, some whole-meal
biscuits, possibly a wooden vesta, and perhaps even the missing hat.”
At the mention of the hat, the inspector stepped eagerly to the back
door, but, finding it bolted, he tried the window. This also was
securely fastened and, on Thorndyke’s advice, we went round to the
front door.
“This door is locked too,” said the inspector. “I’m afraid we shall
have to break in. It’s a nuisance, though.”
“Have a look at the window,” suggested Thorndyke.
The officer did so, struggling vainly to undo the patent catch with
his pocket-knife.
“It’s no go,” he said, coming back to the door. “We shall have
to----” He broke off with an astonished stare, for the door stood
open and Thorndyke was putting something in his pocket.
“Your friend doesn’t waste much time--even in picking a lock,” he
remarked to me, as we followed Thorndyke into the house; but his
reflections were soon merged in a new surprise. Thorndyke had
preceded us into a small sitting-room dimly lighted by a hanging lamp
turned down low.
As we entered he turned up the light and glanced about the room. A
whisky-bottle was on the table, with a siphon, a tumbler and a
biscuit-box. Pointing to the latter, Thorndyke said to the inspector:
“See what is in that box.”
The inspector raised the lid and peeped in, the station master peered
over his shoulder, and then both stared at Thorndyke.
“How in the name of goodness did you know that there were whole-meal
biscuits in the house, sir?” exclaimed the station-master.
“You’d be disappointed if I told you,” replied Thorndyke. “But look
at this.” He pointed to the hearth, where lay a flattened,
half-smoked cigarette and a round wooden vesta. The inspector gazed
at these objects in silent wonder, while, as to the station-master,
he continued to stare at Thorndyke with what I can only describe as
superstitious awe.
“You have the dead man’s property with you, I believe?” said my
colleague.
“Yes,” replied the inspector; “I put the things in my pocket for
safety.”
“Then,” said Thorndyke, picking up the flattened cigarette, “let us
have a look at his tobacco-pouch.”
As the officer produced and opened the pouch, Thorndyke neatly cut
open the cigarette with his sharp pocket-knife. “Now,” said he, “what
kind of tobacco is in the pouch?”
The inspector took out a pinch, looked at it and smelt it
distastefully. “It’s one of those stinking tobaccos,” he said, “that
they put in mixtures--Latakia, I think.”
“And what is this?” asked Thorndyke, pointing to the open cigarette.
“Same stuff, undoubtedly,” replied the inspector.
“And now let us see his cigarette papers,” said Thorndyke.
The little book, or rather packet--for it consisted of separated
papers--was produced from the officer’s pocket and a sample paper
abstracted. Thorndyke laid the half burnt paper beside it, and the
inspector, having examined the two, held them up to the light.
“There isn’t much chance of mistaking that ‘Zig-Zag’ watermark,” he
said. “This cigarette was made by the deceased; there can’t be the
shadow of a doubt.”
“One more point,” said Thorndyke, laying the burnt wooden vesta on
the table. “You have his match-box?”
The inspector brought forth the little silver casket, opened it and
compared the wooden vestas that it contained with the burnt end. Then
he shut the box with a snap.
“You’ve proved it up to the hilt,” said he. “If we could only find
the hat, we should have a complete case.”
“I’m not sure that we haven’t found the hat,” said Thorndyke. “You
notice that something besides coal has been burned in the grate.”
The inspector ran eagerly to the fire-place and began with feverish
hands, to pick out the remains of the extinct fire. “The cinders are
still warm,” he said, “and they are certainly not all coal cinders.
There has been wood burned here on top of the coal, and these little
black lumps are neither coal nor wood. They may quite possibly be the
remains of a burnt hat, but, lord! who can tell? You can put together
the pieces of broken spectacle-glasses, but you can’t build up a hat
out of a few cinders.” He held out a handful of little, black, spongy
cinders and looked ruefully at Thorndyke, who took them from him and
laid them out on a sheet of paper.
“We can’t reconstitute the hat, certainly,” my friend agreed, “but we
may be able to ascertain the origin of these remains. They may not be
cinders of a hat, after all.” He lit a wax match and, taking up one
of the charred fragments, applied the flame to it. The cindery mass
fused at once with a crackling, seething sound, emitting a dense
smoke, and instantly the air became charged with a pungent, resinous
odour mingled with the smell of burning animal matter.
“Smells like varnish,” the station-master remarked.
“Yes. Shellac,” said Thorndyke; “so the first test gives a positive
result. The next test will take more time.”
He opened the green case and took from it a little flask, fitted for
Marsh’s arsenic test, with a safety funnel and escape tube, a small
folding tripod, a spirit lamp and a disc of asbestos to serve as a
sand-bath. Dropping into the flask several of the cindery masses,
selected after careful inspection, he filled it up with alcohol and
placed it on the disc, which he rested on the tripod. Then he lighted
the spirit lamp underneath and sat down to wait for the alcohol to
boil.
“There is one little point that we may as well settle,” he said
presently, as the bubbles began to rise in the flask. “Give me a
slide with a drop of Farrant on it, Jervis.”
I prepared the slide while Thorndyke, with a pair of forceps, picked
out a tiny wisp from the table-cloth. “I fancy we have seen this
fabric before,” he remarked, as he laid the little pinch of fluff in
the mounting fluid and slipped the slide onto the stage of the
microscope. “Yes,” he continued, looking into the eye-piece, “here
are our old acquaintances, the red wool fibres, the blue cotton and
the yellow jute. We must label this at once or we may confuse it with
the other specimens.”
“Have you any idea how the deceased met his death?” the inspector
asked.
“Yes,” replied Thorndyke. “I take it that the murderer enticed him
into this room and gave him some refreshments. The murderer sat in
the chair in which you are sitting, Brodski sat in that small
arm-chair. Then I imagine the murderer attacked him with that iron
bar that you found among the nettles, failed to kill him at the first
stroke, struggled with him and finally suffocated him with the
tablecloth. By the way, there is just one more point. You recognize
this piece of string?” He took from his “collecting-box” the little
end of twine that had been picked up by the line. The inspector
nodded. “Look behind you, you will see where it came from.”
The officer turned sharply and his eye lighted on a string box on the
mantelpiece. He lifted it down, and Thorndyke drew out from it a
length of white twine with one green strand, which he compared with
the piece in his hand. “The green strand in it makes the
identification fairly certain,” he said. “Of course the string was
used to secure the umbrella and hand-bag. He could not have carried
them in his hand, encumbered as he was with the corpse. But I expect
our other specimen is ready now.” He lifted the flask off the tripod,
and, giving it a vigorous shake, examined the contents through his
lens. The alcohol had now become dark-brown in colour, and was
noticeably thicker and more syrupy in consistence.
“I think we have enough here for a rough test,” said he, selecting a
pipette and a slide from the case. He dipped the former into the
flask and, having sucked up a few drops of the alcohol from the
bottom, held the pipette over the slide on which he allowed the
contained fluid to drop.
Laying a cover-glass on the little pool of alcohol, he put the slide
on the microscope stage and examined it attentively, while we watched
him in expectant silence.
At length he looked up, and, addressing the inspector, asked: “Do you
know what felt hats are made of?”
“I can’t say that I do, sir,” replied the officer.
“Well, the better quality hats are made of rabbits’ and hares’
wool--the soft under-fur, you know--cemented together with shellac.
Now there is very little doubt that these cinders contain shellac,
and with the microscope I find a number of small hairs of a rabbit. I
have, therefore, little hesitation in saying that these cinders are
the remains of a hard felt hat; and, as the hairs do not appear to be
dyed, I should say it was a grey hat.”
At this moment our conclave was interrupted by hurried footsteps on
the garden path and, as we turned with one accord, an elderly woman
burst into the room.
She stood for a moment in mute astonishment, and then, looking from
one to the other, demanded: “Who are you? and what are you doing
here?”
The inspector rose. “I am a police officer, madam,” said he. “I can’t
give you any further information just now, but, if you will excuse me
asking, who are you?”
“I am Mr. Hickler’s housekeeper,” she replied.
“And Mr. Hickler; are you expecting him home shortly?”
“No, I am not,” was the curt reply. “Mr. Hickler is away from home
just now. He left this evening by the boat train.”
“For Amsterdam?” asked Thorndyke.
“I believe so, though I don’t see what business it is of yours,” the
housekeeper answered.
“I thought he might, perhaps, be a diamond broker or merchant,” said
Thorndyke. “A good many of them travel by that train.”
“So he is,” said the woman, “at least, he has something to do with
diamonds.”
“Ah. Well, we must be going, Jervis,” said Thorndyke, “we have
finished here, and we have to find an hotel or inn. Can I have a word
with you, inspector?”
The officer, now entirely humble and reverent, followed us out into
the garden to receive Thorndyke’s parting advice.
“You had better take possession of the house at once, and get rid of
the housekeeper. Nothing must be removed. Preserve those cinders and
see that the rubbish-heap is not disturbed, and, above all, don’t
have the room swept. An officer will be sent to relieve you.”
With a friendly “good-night” we went on our way, guided by the
station-master; and here our connection with the case came to an end.
Hickler (whose Christian name turned out to be Silas) was, it is
true, arrested as he stepped ashore from the steamer, and a packet of
diamonds, subsequently identified as the property of Oscar Brodski,
found upon his person. But he was never brought to trial, for on the
return voyage he contrived to elude his guards for an instant as the
ship was approaching the English coast, and it was not until three
days later, when a hand-cuffed body was cast up on the lonely shore
by Orfordness, that the authorities knew the fate of Silas Hickler.
“An appropriate and dramatic end to a singular and yet typical case,”
said Thorndyke, as he put down the newspaper. “I hope it has enlarged
your knowledge, Jervis, and enabled you to form one or two useful
corollaries.”
“I prefer to hear you sing the medico-legal doxology,” I answered,
turning upon him like the proverbial worm and grinning derisively
(which the worm does not).
“I know you do,” he retorted, with mock gravity, “and I lament your
lack of mental initiative. However, the points that this case
illustrates are these: First, the danger of delay; the vital
importance of instant action before that frail and fleeting thing
that we call a clue has time to evaporate. A delay of a few hours
would have left us with hardly a single datum. Second, the necessity
of pursuing the most trivial clue to an absolute finish, as
illustrated by the spectacles. Third, the urgent need of a trained
scientist to aid the police; and, last,” he concluded, with a smile,
“we learn never to go abroad without the invaluable green case.”
A CASE OF PREMEDITATION
