CHAPTER X

POLTON IS MYSTIFIED

A couple of days sufficed to prove that Thorndyke's mishap was not to be

productive of any permanent ill consequences; his wounds progressed

favourably and he was able to resume his ordinary avocations.

Miss Gibson's visit--but why should I speak of her in these formal

terms? To me, when I thought of her, which I did only too often, she was

Juliet, with perhaps an adjective thrown in; and as Juliet I shall

henceforth speak of her (but without the adjective) in this narrative,

wherein nothing has been kept back from the reader--Juliet's visit,

then, had been a great success, for my colleague was really pleased by

the attention, and displayed a quiet geniality that filled our visitor

with delight.

He talked a good deal of Reuben, and I could see that he was

endeavouring to settle in his own mind the vexed question of her

relations with and sentiments towards our unfortunate client; but what

conclusions he arrived at I was unable to discover, for he was by no

means communicative after she had left. Nor was there any repetition of

the visit--greatly to my regret--since, as I have said, he was able, in

a day or two, to resume his ordinary mode of life.

The first evidence I had of his renewed activity appeared when I

returned to the chambers at about eleven o'clock in the morning, to find

Polton hovering dejectedly about the sitting-room, apparently

perpetrating as near an approach to a "spring clean" as could be

permitted in a bachelor establishment.

"Hallo, Polton!" I exclaimed, "have you contrived to tear yourself away

from the laboratory for an hour or two?"

"No, sir," he answered gloomily. "The laboratory has torn itself away

from me."

"What do you mean?" I asked.

"The Doctor has shut himself in and locked the door, and he says I am

not to disturb him. It will be a cold lunch to-day."

"What is he doing in there?" I inquired.

"Ah!" said Polton, "that's just what I should like to know. I'm fair

eaten up with curiosity. He is making some experiments in connection

with some of his cases, and when the Doctor locks himself in to make

experiments, something interesting generally follows. I should like to

know what it is this time."

"I suppose there is a keyhole in the laboratory door?" I suggested, with

a grin.

"Sir!" he exclaimed indignantly. "Dr. Jervis, I am surprised at you."

Then, perceiving my facetious intent, he smiled also and added: "But

there _is_ a keyhole if you'd like to try it, though I'll wager the

Doctor would see more of you than you would of him."

"You are mighty secret about your doings, you and the Doctor," I said.

"Yes," he answered. "You see, it's a queer trade this of the Doctor's,

and there are some queer secrets in it. Now, for instance, what do you

make of this?"

He produced from his pocket a leather case, whence he took a piece of

paper which he handed to me. On it was a neatly executed drawing of what

looked like one of a set of chessmen, with the dimensions written on the

margin.

"It looks like a pawn--one of the Staunton pattern," I said.

"Just what I thought; but it isn't. I've got to make twenty-four of

them, and what the Doctor is going to do with them fairly beats me."

"Perhaps he has invented some new game," I suggested facetiously. "He

is always inventing new games and playing them mostly in courts of law,

and then the other players generally lose. But this is a puzzler, and no

mistake. Twenty-four of these to be turned up in the best-seasoned

boxwood! What can they be for? Something to do with the experiments he

is carrying on upstairs at this very moment, I expect." He shook his

head, and, having carefully returned the drawing to his pocket-book,

said, in a solemn tone--"Sir, there are times when the Doctor makes me

fairly dance with curiosity. And this is one of them."

Although not afflicted with a curiosity so acute as that of Polton, I

found myself speculating at intervals on the nature of my colleague's

experiments and the purpose of the singular little objects which he had

ordered to be made; but I was unacquainted with any of the cases on

which he was engaged, excepting that of Reuben Hornby, and with the

latter I was quite unable to connect a set of twenty-four boxwood

chessmen. Moreover, on this day, I was to accompany Juliet on her second

visit to Holloway, and that circumstance gave me abundant mental

occupation of another kind.

At lunch, Thorndyke was animated and talkative but not communicative. He

"had some work in the laboratory that he must do himself," he said, but

gave no hint as to its nature; and as soon as our meal was finished, he

returned to his labours, leaving me to pace up and down the walk,

listening with ridiculous eagerness for the sound of the hansom that was

to transport me to the regions of the blest, and--incidentally--to

Holloway Prison.

When I returned to the Temple, the sitting-room was empty and hideously

neat, as the result of Polton's spring-cleaning efforts. My colleague

was evidently still at work in the laboratory, and, from the

circumstance that the tea-things were set out on the table and a kettle

of water placed in readiness on the gas-ring by the fireplace, I

gathered that Polton also was full of business and anxious not to be

disturbed.

Accordingly, I lit the gas and made my tea, enlivening my solitude by

turning over in my mind the events of the afternoon.

Juliet had been charming--as she always was--frank, friendly and

unaffectedly pleased to have my companionship. She evidently liked me

and did not disguise the fact--why should she indeed?--but treated me

with a freedom, almost affectionate, as though I had been a favourite

brother; which was very delightful, and would have been more so if I

could have accepted the relationship. As to her feelings towards me, I

had not the slightest misgiving, and so my conscience was clear; for

Juliet was as innocent as a child, with the innocence that belongs to

the direct, straightforward nature that neither does evil itself nor

looks for evil motives in others. For myself, I was past praying for.

The thing was done and I must pay the price hereafter, content to

reflect that I had trespassed against no one but myself. It was a

miserable affair, and many a heartache did it promise me in the lonely

days that were to come, when I should have said "good-bye" to the Temple

and gone back to my old nomadic life; and yet I would not have had it

changed if I could; would not have bartered the bitter-sweet memories

for dull forgetfulness.

But other matters had transpired in the course of our drive than those

that loomed so large to me in the egotism of my love. We had spoken of

Mr. Hornby and his affairs, and from our talk there had emerged certain

facts of no little moment to the inquiry on which I was engaged.

"Misfortunes are proverbially sociable," Juliet had remarked, in

reference to her adopted uncle. "As if this trouble about Reuben were

not enough, there are worries in the city. Perhaps you have heard of

them."

I replied that Walter had mentioned the matter to me.

"Yes," said Juliet rather viciously; "I am not quite clear as to what

part that good gentleman has played in the matter. It has come out,

quite accidentally, that he had a large holding in the mines himself,

but he seems to have 'cut his loss,' as the phrase goes, and got out of

them; though how he managed to pay such large differences is more than

we can understand. We think he must have raised money somehow to do it."

"Do you know when the mines began to depreciate?" I asked.

"Yes, it was quite a sudden affair--what Walter calls 'a slump'--and it

occurred only a few days before the robbery. Mr. Hornby was telling me

about it only yesterday, and he recalled it to me by a ridiculous

accident that happened on that day."

"What was that?" I inquired.

"Why, I cut my finger and nearly fainted," she answered, with a

shamefaced little laugh. "It was rather a bad cut, you know, but I

didn't notice it until I found my hand covered with blood. Then I turned

suddenly faint, and had to lie down on the hearthrug--it was in Mr.

Hornby's study, which I was tidying up at the time. Here I was found by

Reuben, and a dreadful fright it gave him at first; and then he tore up

his handkerchief to tie up the wounded finger, and you never saw such an

awful mess as he got his hands in. He might have been arrested as a

murderer, poor boy, from the condition he was in. It will make your

professional gorge rise to learn that he fastened up the extemporised

bandage with red tape, which he got from the writing table after rooting

about among the sacred papers in the most ruthless fashion.

"When he had gone I tried to put the things on the table straight again,

and really you might have thought some horrible crime had been

committed; the envelopes and papers were all smeared with blood and

marked with the print of gory fingers. I remembered it afterwards, when

Reuben's thumb-mark was identified, and thought that perhaps one of the

papers might have got into the safe by accident; but Mr. Hornby told me

that was impossible; he tore the leaf off his memorandum block at the

time when he put away the diamonds."

Such was the gist of our conversation as the cab rattled through the

streets on the way to the prison; and certainly it contained matter

sufficiently important to draw away my thoughts from other subjects,

more agreeable, but less relevant to the case. With a sudden remembrance

of my duty, I drew forth my notebook, and was in the act of committing

the statements to writing, when Thorndyke entered the room.

"Don't let me interrupt you, Jervis," said he. "I will make myself a cup

of tea while you finish your writing, and then you shall exhibit the

day's catch and hang your nets out to dry."

I was not long in finishing my notes, for I was in a fever of impatience

to hear Thorndyke's comments on my latest addition to our store of

information. By the time the kettle was boiling my entries were

completed, and I proceeded forthwith to retail to my colleague those

extracts from my conversation with Juliet that I have just recorded.

He listened, as usual, with deep and critical attention.

"This is very interesting and important," he said, when I had finished;

"really, Jervis, you are a most invaluable coadjutor. It seems that

information, which would be strictly withheld from the forbidding

Jorkins, trickles freely and unasked into the ear of the genial Spenlow.

Now, I suppose you regard your hypothesis as having received very

substantial confirmation?"

"Certainly, I do."

"And very justifiably. You see now how completely you were in the right

when you allowed yourself to entertain this theory of the crime in spite

of its apparent improbability. By the light of these new facts it has

become quite a probable explanation of the whole affair, and if it could

only be shown that Mr. Hornby's memorandum block was among the papers on

the table, it would rise to a high degree of probability. The obvious

moral is, never disregard the improbable. By the way, it is odd that

Reuben failed to recall this occurrence when I questioned him. Of

course, the bloody finger-marks were not discovered until he had gone,

but one would have expected him to recall the circumstance when I asked

him, pointedly, if he had never left bloody finger-prints on any

papers."

"I must try to find out if Mr. Hornby's memorandum block was on the

table and among the marked papers," I said.

"Yes, that would be wise," he answered, "though I don't suppose the

information will be forthcoming."

My colleague's manner rather disappointed me. He had heard my report

with the greatest attention, he had discussed it with animation, but yet

he seemed to attach to the new and--as they appeared to me--highly

important facts an interest that was academic rather than practical. Of

course, his calmness might be assumed; but this did not seem likely, for

John Thorndyke was far too sincere and dignified a character to

cultivate in private life the artifices of the actor. To strangers,

indeed, he presented habitually a calm and impassive exterior; but this

was natural to him, and was but the outward sign of his even and

judicial habit of mind.

No; there was no doubt that my startling news had left him unmoved, and

this must be for one of two reasons: either he already knew all that I

had told him (which was perfectly possible), or he had some other and

better means of explaining the crime. I was turning over these two

alternatives, not unobserved by my watchful colleague, when Polton

entered the room; a broad grin was on his face, and a drawing-board,

that he carried like a tray, bore twenty-four neatly turned boxwood

pieces.

Thorndyke at once entered into the unspoken jest that beamed from the

countenance of his subordinate.

"Here is Polton with a problem for you, Jervis," he said. "He assumes

that I have invented a new parlour game, and has been trying to work out

the moves. Have you succeeded yet, Polton?"

"No, sir, I haven't; but I suspect that one of the players will be a man

in a wig and gown."

"Perhaps you are right," said Thorndyke; "but that doesn't take you very

far. Let us hear what Dr. Jervis has to say."

"I can make nothing of them," I answered. "Polton showed me the drawing

this morning, and then was terrified lest he had committed a breach of

confidence, and I have been trying ever since, without a glimmer of

success, to guess what they can be for."

"H'm," grunted Thorndyke, as he sauntered up and down the room, teacup

in hand, "to guess, eh? I like not that word 'guess' in the mouth of a

man of science. What do you mean by a 'guess'?"

His manner was wholly facetious, but I professed to take his question

seriously, and replied--

"By a guess, I mean a conclusion arrived at without data."

"Impossible!" he exclaimed, with mock sternness. "Nobody but an utter

fool arrives at a conclusion without data."

"Then I must revise my definition instantly," I rejoined. "Let us say

that a guess is a conclusion drawn from insufficient facts."

"That is better," said he; "but perhaps it would be better still to say

that a guess is a particular and definite conclusion deduced from facts

which properly yield only a general and indefinite one. Let us take an

instance," he continued. "Looking out of the window, I see a man walking

round Paper Buildings. Now suppose I say, after the fashion of the

inspired detective of the romances, 'That man is a stationmaster or

inspector,' that would be a guess. The observed facts do not yield the

conclusion, though they do warrant a conclusion less definite and more

general."

"You'd have been right though, sir!" exclaimed Polton, who had stepped

forward with me to examine the unconscious subject of the demonstration.

"That gent used to be the stationmaster at Camberwell. I remember him

well." The little man was evidently greatly impressed.

"I happen to be right, you see," said Thorndyke; "but I might as easily

have been wrong."

"You weren't though, sir," said Polton. "You spotted him at a glance."

In his admiration of the result he cared not a fig for the correctness

of the means by which it had been attained.

"Now why do I suggest that he is a stationmaster?" pursued Thorndyke,

disregarding his assistant's comment.

"I suppose you were looking at his feet," I answered. "I seem to have

noticed that peculiar, splay-footed gait in stationmasters, now that you

mention it."

"Quite so. The arch of the foot has given way; the plantar ligaments

have become stretched and the deep calf muscles weakened. Then, since

bending of the weakened arch causes discomfort, the feet have become

turned outwards, by which the bending of the foot is reduced to a

minimum; and as the left foot is the more flattened, so it is turned out

more than the right. Then the turning out of the toes causes the legs to

splay outward from the knees downwards--a very conspicuous condition in

a tall man like this one--and you notice that the left leg splays out

more than the other.

"But we know that depression of the arch of the foot is brought about by

standing for long periods. Continuous pressure on a living structure

weakens it, while intermittent pressure strengthens it; so the man who

stands on his feet continuously develops a flat instep and a weak calf,

while the professional dancer or runner acquires a high instep and a

strong calf. Now there are many occupations which involve prolonged

standing and so induce the condition of flat foot: waiters,

hall-porters, hawkers, policemen, shop-walkers, salesmen, and station

officials are examples. But the waiter's gait is characteristic--a

quick, shuffling walk which enables him to carry liquids without

spilling them. This man walks with a long, swinging stride; he is

obviously not a waiter. His dress and appearance in general exclude the

idea of a hawker or even a hall-porter; he is a man of poor physique and

so cannot be a policeman. The shop-walker or salesman is accustomed to

move in relatively confined spaces, and so acquires a short, brisk step,

and his dress tends to rather exuberant smartness; the station official

patrols long platforms, often at a rapid pace, and so tends to take long

strides, while his dress is dignified and neat rather than florid. The

last-mentioned characteristics, you see, appear in the subject of our

analysis; he agrees with the general description of a stationmaster. But

if we therefore conclude that he _is_ a stationmaster, we fall into the

time-honoured fallacy of the undistributed middle term--the fallacy that

haunts all brilliant guessers, including the detective, not only of

romance, but too often also of real life. All that the observed facts

justify us in inferring is that this man is engaged in some mode of life

that necessitates a good deal of standing; the rest is mere guess-work."

"It's wonderful," said Polton, gazing at the now distant figure;

"perfectly wonderful. I should never have known he was a stationmaster."

With this and a glance of deep admiration at his employer, he took his

departure.

"You will also observe," said Thorndyke, with a smile, "that a fortunate

guess often brings more credit than a piece of sound reasoning with a

less striking result."

"Yes, that is unfortunately the case, and it is certainly true in the

present instance. Your reputation, as far as Polton is concerned, is now

firmly established even if it was not before. In his eyes you are a

wizard from whom nothing is hidden. But to return to these little

pieces, as I must call them, for the lack of a better name. I can form

no hypothesis as to their use. I seem to have no 'departure,' as the

nautical phrase goes, from which to start an inquiry. I haven't even the

material for guess-work. Ought I to be able to arrive at any opinion on

the subject?"

Thorndyke picked up one of the pieces, fingering it delicately and

inspecting with a critical eye the flat base on which it stood, and

reflected for a few moments.

"It is easy to trace a connection when one knows all the facts," he said

at length, "but it seems to me that you have the materials from which to

form a conjecture. Perhaps I am wrong, but I think, when you have had

more experience, you will find yourself able to work out a problem of

this kind. What is required is constructive imagination and a rigorous

exactness in reasoning. Now, you are a good reasoner, and you have

recently shown me that you have the necessary imagination; you merely

lack experience in the use of your faculties. When you learn my purpose

in having these things made--as you will before long--you will probably

be surprised that their use did not occur to you. And now let us go

forth and take a brisk walk to refresh ourselves (or perhaps I should

say myself) after the day's labour."
