Chapter XXI.

Roger Plays a Lone Hand

It was some minutes before Roger would agree to abandon, once and for

all time, his cherished theory of suicide. Suicide had smoothed all

difficulties away; suicide had explained both deaths in the simplest

possible terms, reduced them to a common denominator; in spite of

superficial appearances surely in some way it _must_ be suicide. Not

until the inspector had patiently, and for half-a-dozen times in

succession, pointed out that the very last place in which a voluntary

consumer of aconitine would put the poison was among the contents of

his tobacco-jar, and the very last way he would choose of imbibing it

was through the stem of his pipe, did Roger reluctantly admit that,

hang it! yes, it really did begin to look as if the man had been

murdered after all.

“But you don’t think he was under the impression that aconitine was a

narcotic and that he could smoke it like opium and so have an easy

passage?” he suggested as a final gleam of hope.

“I do not,” said the inspector, briskly extinguishing the gleam. “A

man who’s going to use a drug like aconitine at all is going to know

something about it; and the very least he’d know is that it isn’t a

narcotic. No, sir, there’s no other conclusion at all. Meadows was

murdered.”

“Curse the man, then!” Roger observed with feeling. “He’d simply got

no right to be, that’s all I can say. Now we’re put right back to the

beginning again. Well, who murdered him, Inspector? Perhaps you’ll

tell me that too?”

The inspector tugged at his moustache. “I was hoping you’d be able to

tell me that, Mr. Sheringham.”

“I see,” Roger said bitterly. “I might have known you weren’t pouring

out all this confidential information for nothing. You want to pick my

magnificent brains again, I suppose?”

“Well, if you like to put it that way, sir,” remarked the inspector in

deprecating tones.

“I do. I hate calling a pick-axe an ‘agricultural implement.’ All

right, pick away.”

The inspector drank a little beer with a thoughtful air. “Let’s begin

with a motive, then. Now can you see anyone in the case with a motive

for Meadow’s death?”

“Wait a minute. You still think his death is mixed up with Mrs.

Vane’s? You’re taking that as a starting-point?”

“Well, we can always keep the other possibility before us, but it

seems a fair enough assumption, wouldn’t you say?”

“Yes; the balance of probability is certainly in favour of it. But I

don’t think we ought to forget that Meadows (we’ll call him Meadows;

it’s easier) was quite possibly a blackmailer, among his other

activities; and once we admit blackmail the field is enormously

widened.”

“Oh, yes, sir; I’m not forgetting that. But you must remember that he

was certainly down here for some specific purpose to do with his

wife—the coincidence otherwise would be so great that I think we can

wash it out altogether; so if he _was_ blackmailing, it was either his

wife or somebody very closely connected with his wife.”

“Such as her husband?”

“Such as Dr. Vane,” said the inspector meticulously. “Well, you see

what I mean. It seems to me we can take it for granted that his death

_is_ due to somebody already mixed up with the case.”

“Yes,” Roger agreed. “I think you’ve clinched that point.”

“So that brings us back to what I asked you first of all: can you see

anyone in the case with a motive for getting him out of the way?”

“Plenty!” said Roger promptly. “And the one with the biggest motive of

all was Mrs. Vane herself.”

“Excluding her, I was really meaning,” the inspector amplified, with

quite exemplary patience.

“Well, confining ourselves for the moment to the blackmail _motif_, I

suppose Dr. Vane’s the next on the list. He’d have plenty of reason to

get rid of his wife’s real husband, especially if he was threatening

to give the whole show away—as he probably was.”

“Even after his wife was dead? What would it matter to the doctor

then?”

“Everything! Nobody likes to be shown up as a credulous fool, imposed

upon by a clever and unscrupulous woman. Besides, there are bound to

be reasons there that we don’t know anything about, wheels within

wheels. How do we know, for instance, that she hadn’t somehow made him

an accessory to some real breach of the law? It would be a useful

weapon for a woman in such a precarious position as she was. And

Meadows might have got wind of it.”

“Very ingenious, sir,” the inspector approved. “Yes, you make out

quite a pretty case against the doctor; though how you’re going to

prove it is a different matter. And now cutting out the blackmail

idea—or rather, taking another aspect of it. Who after all, whether it

was Dr. Vane or not, would have the greatest incentive to put Meadows

out of the way—to ensure his mouth being shut for ever, if you like?”

Roger nodded slowly. “I see. Yes; of course. And we know Meadows was

on the spot at the time; I was forgetting that. Yes, certainly that’s

the strongest motive of all.”

“That’s how I look at it, anyway,” said the inspector cheerfully. “In

fact, the way I see it is this. Meadows was in that little cave at the

time, probably waiting to keep an appointment with his wife. Along she

comes, but—with somebody else; not alone. Naturally he lies low;

doesn’t want his name connected with hers at all; that might be

killing the goose with the golden eggs. And while he’s waiting, this

other person pushes his wife over the cliff—_and he knows who that

person is_.”

“A masterly reconstruction,” Roger commented. “So although the

original goose is killed, the gander that did it has delivered himself

into his hands; and contrary to all the laws of nature, that gander is

going to be made to shell out golden eggs just as fast as a

sausage-machine!”

“That’s one way of putting it,” the inspector smiled. “But the gander

thinks differently, and——”

“As Samuel is promptly despatched to fresh meadows and pastures

new!—Well, yes, Inspector, one must admit that’s a sound enough

theory, and very cogently stated.”

“Doesn’t it seem to you the only reasonable theory, sir? Or at any

rate, the most reasonable?”

“I suppose it does,” Roger said thoughtfully. “Yes, the most

reasonable, without doubt. So now we come back to the good old

problem, which I solved so extremely neatly last week—who killed Mrs.

Vane?”

“We do, sir. And as to that, do you see one big fact in this second

case which is going to give us a valuable pointer to the identity of

the double murderer?”

“This is as good as a correspondence course,” Roger murmured: “‘How to

Be a Detective,’ in three lessons—Yes, Teacher, I do. Aconitine.”

“That’s right, sir. It must have been somebody who had access to

aconitine; I think we can take _that_ for granted. I shall make

enquiries at the chemist’s in Sandsea and elsewhere, of course, as a

matter of form; but I don’t fancy they’ll lead to anything. The

murderer knew all about poisons; that’s obvious. Something was wanted

that would act quickly, so the choice was practically limited to

prussic acid, strychnine, aconitine and curare. Prussic acid smells

too strong, so the man could hardly be induced to take it

unsuspectingly; with strychnine he’d shout out and make too much fuss;

curare won’t act except on an open wound; aconitine (a _big_ dose of

aconitine, that is) was just what was wanted.”

“Humph!” Roger said seriously, stroking his chin. “I see what you’re

getting at, of course. But do you really think he——”

“Hullo, you two!” said a voice from the door. “Still yapping? Hope

you’ve got something to drink up here. I’ve got a throat like a

mustard plaster after walking along that road in this heat.”

“Anthony,” said his cousin with not unjustified annoyance, “you’re

gross.”

The conversation swerved abruptly from matters criminal.

__________________________________________________________________

Lying in bed that night, Roger did not get to sleep very quickly.

Apart from this fresh development of the case which in itself was

enough to prolong his meditations well into the small hours, he had

another problem to engage his attention scarcely less closely—_why_

had the inspector emerged, practically unbidden, from his shell of

reticence and volunteered this startling information? The pretext of

picking his amateur colleague’s brains was of course only an empty

excuse, for in the subsequent discussion it was the inspector who had

taken the lead, pointed out the possibilities and established a

workable theory; Roger had contributed nothing of any value to it.

Why, in other words, had the inspector gone out of his way to drop

unmistakable hints that the author of both crimes was Dr. Vane

himself? It was only as he was at last dropping off to sleep that an

illuminating answer occurred to him—the inspector had done this

because that is what he wished Roger to think: his real theory was

something entirely different!

__________________________________________________________________

Shaving the next morning, Roger pursued this train of thought. That

certainly was the explanation of the inspector’s otherwise

inexplicable conduct. Laughing maliciously up his sleeve, he had been

trying to head the officious journalist, against whom he already had a

score to pay, not toward the truth but away from it. Roger grinned at

his reflection in the mirror: very well, but two could play at that

game. Likewise, forewarned was forearmed. He began to ponder a plan of

campaign which should end in extracting the wind from the inspector’s

sails.

Obviously the only thing to do was to go straight ahead with his

investigations as if nothing had been said. It was possible of course

that Dr. Vane really was the murderer, although the inspector clearly

did not think so. Nor for that matter did Roger himself. Not that Dr.

Vane struck him as likely to shrink from murder if murder should be

necessary, but somehow he did not _feel_ him as the murderer of his

wife—he could put it no more reasonably than that; the eliminator of

Meadows, yes, quite possibly; but not the other.

And in that connection, was it so unlikely that the two deaths should

have been brought about by different agents? The inspector had

pretended to think so and had certainly made out a strong case to

support his hypothesis, but did that not now point all the more

strongly to the opposite conclusion? The inspector had been at some

pains even to labour the point; all the more reason therefore to

suspect that his real opinion was just the opposite. Well, well,

things did seem to be getting really very involved. The only way of

straightening them out was to keep a clear head, forget no

possibilities and yet allow none to bias him unduly—and might the best

sleuth win!

Roger brushed his hair with his usual care, put on his coat and walked

demurely down to breakfast.

The inspector was already half-way through his meal, and Anthony had

not put in an appearance. For ten minutes the two exchanged

platitudes, the topic bulking largest in both of their minds being as

if by common consent avoided. Then the inspector mumbled something

about having a busy day in front of him and took his departure. Almost

simultaneously Anthony entered the room.

Roger helped himself to marmalade and watched Anthony scoop the

remainder of the dish of bacon and eggs on to his plate. He had

devoted some earnest thought between platitudes during the last ten

minutes to the promise the inspector had extracted from him the

evening before, and while deprecating any temptation to break it even

in the circumstances, fancied that he had found a blameless way round

it. “Anthony,” he began with some care, “you’re on duty this morning.”

“Right-ho!” said Anthony with equanimity. “But what’s the idea?

Nothing for us to do, is there?”

“Well, yes,” Roger said, with elaborate carelessness. “At least,

nothing _necessary;_ just something I’d rather like to play about

with. To tell you the truth, Anthony, I’m getting a little tired of

this enforced idleness, so I’ve propounded a neat little puzzle to

myself. It’s this: suppose Meadows turned out after all not to have

committed suicide, but to have been murdered!”

“Suppose the moon turned into pink cheese too,” responded Anthony

jocularly. “All right, I’ll suppose that. What about it?”

“Well, you know, it _is_ a possibility,” Roger said, with an air of

trying to convince himself against his reason. “We ought not to lose

sight of it just because it seems improbable. And it would be

remarkably interesting if we could make out some sort of a case to

support it, wouldn’t it?”

“Is that what you want to do?” Anthony asked, cutting himself a second

slice of bread. “Seems a bit of a waste of time to me. However, I’m

game if you want to amuse yourself. Things have been a bit quiet

lately, haven’t they?”

Roger glanced at his cousin in some surprise, but tactfully forebore

to comment on this remarkable statement. It had been his impression

that things had not been at all quiet lately, so far as Anthony and

his affairs were concerned. “You haven’t fixed anything up with

Margaret for this morning, then?” was all he said.

“No,” said Anthony very airily. “She’s got to go into Sandsea, I

believe. Shopping, or some rot. I shan’t be seeing her till to-morrow,

if then.”

Again Roger, with almost superhuman tact this time, refrained from

comment. It was on the tip of his tongue to say, “What have you

quarrelled about now, you pair of idiots?” but he didn’t. For one

thing he had no wish to be accompanied all the morning by a glowering

and resentful Anthony.

“That’s all right then,” he remarked briskly, as if for Anthony and

Margaret not to meet during a whole twenty-four hours was quite the

most ordinary thing in the world. “Well, I’ll tell you what we’ll do.

I think it would be rather fun, to say nothing of the exercise in

detectiveship, to assume for one day that Meadows was murdered

(poisoned, of course) and see if we can collect any evidence in

support of the notion. What do you say?”

“Frightful fun,” Anthony agreed mechanically.

“That’s the spirit,” said Roger with great heartiness. “Very well,

then; hurry up with your breakfast, and we’ll see what the Queen will

send us.”
