Chapter XIV.

Roger Is Argumentative

Roger dabbled his bare foot in the wave which surged past the rock

upon which he and Anthony were sitting. Lifting it out of the water,

he contemplated his dripping toes with apparently deep interest. “Of

course,” he said slowly, “we must remember that Colin _may_ have been

telling the truth, after all.”

“How can he have been?” demanded his cousin.

It was after breakfast on the following morning. On the plea that

business was business and that if he was to be any use in this affair

at all Anthony must temporarily divest himself of the rôle of

interesting young lover and assume that of the idiot friend, Roger had

managed to restrain his cousin from making a hopeful bee-line,

immediately his last mouthful had been swallowed, along the top of the

cliffs in the direction of a certain small grassy ledge just below

their summit. With tactlessly patent reluctance Anthony had been

persuaded to bring his after-breakfast pipe down to the sea level,

where Roger had insisted upon scrambling out to the very farthest rock

which remained unsubmerged in order, as he carefully explained, to

obtain the necessary privacy for airing his theories. There he had

immediately removed his shoes and socks and proceeded to paddle.

Making the best of a bad business, Anthony had watched with a cold eye

his cousin’s undignified behaviour and unhesitatingly refused to

follow such infantile deportment.

“How can Woodthorpe have been telling the truth?” he repeated, as

Roger showed signs of being less interested in his question than in a

limpet which was sturdily countering all his efforts to dislodge it

from its native rock. “That copy of _London Opinion_ clinches that. If

the inspector’s got any sense at all, he’ll draw the same deduction

from it as we did and arrest the fellow right away, before he bolts.”

Roger abandoned the limpet with a slight sigh. “But supposing,

Anthony, that it wasn’t Woodthorpe who left it there at all?” he said

patiently. “Hadn’t that occurred to you?”

“No, it hadn’t,” Anthony returned, not without scorn. “It’s so dashed

likely, isn’t it? You said yourself that it couldn’t have been Mrs.

Vane. Who else could it have been?”

“Ah!” said Roger thoughtfully. “Who, indeed?” He withdrew his feet

from the water and, hunching his knees, clasped his hands round them

and stared out to sea. “Now just let’s see, for the sake of argument,

what we can deduce from that copy of _London Opinion_, shall we?

Forgetting for the moment all about Woodthorpe, I mean, and our slight

complex about his veracity. Shall we do that, Anthony?”

“Fire ahead, then,” replied his cousin resignedly.

“Well in the first place, and confining ourselves to bare

probabilities, with every likelihood of error, who constitute the

majority of _London Opinion’s_ public, would you say? Men. That’s why

I advanced the unlikelihood of Mrs. Vane having left it there; it

doesn’t sound to me at all the type of paper that we might expect to

find Mrs. Vane reading. Besides, she’s much more likely to have

brought a novel. Do you agree, so far?”

Anthony grunted.

“Very well, then; in all probability that paper was left there some

time since last Saturday morning, by a man. Now what _type_ of man

reads _London Opinion?_ Not the upper classes; they read _Punch_. Not

the lower classes either. The middle classes—upper, middle and lower

middle-classes. Our man, therefore, was probably an upper, middle or

lower middle-class man. Now that doesn’t sound very much like the son

of Sir Henry Woodthorpe, does it?”

“Are you trying to make out that just because a chap’s father is a

baronet, he never reads _London Opinion?_” enquired Anthony with some

sarcasm.

“No, Anthony, I am not. You tend to miss my point. What I am very

brilliantly endeavouring to convey to your moss-covered intelligence

is that if Mr. Colin Woodthorpe, son of Sir Henry Woodthorpe, Bart.,

wanted to take a piece of literature with which to amuse himself while

waiting for the other half of an appointment he’d probably take the

_Sporting Life_, _Punch_, or a detective novel. That he might very

nearly as well have taken _London Opinion_ I readily admit, but only

very nearly. What I’m considering, in fact, is the balance of

probabilities. Now are you there?”

“But how do you know that the chap, whoever he was, did take it to

amuse himself with while waiting for an appointment? How do you know

there was an appointment at all?”

“I don’t, bandicoot,” Roger returned with exemplary patience. “But do

you imagine (a) that he took it to read _during_ the appointment,

fearing lest he should be bored by the lady’s idle prattle; or (b)

that he went down to that ledge all alone and crept into that cave for

the sole purpose of reading _London Opinion_ in the dark?”

“He might just as well have simply happened to have it with him, and

chucked it away because he couldn’t be bothered to carry it home

again.”

“He might,” Roger agreed at once; “but it isn’t nearly so likely. No,

on the balance of probabilities I think we may assume that this man,

probably not Woodthorpe, probably took _London Opinion_ with him to

read on the ledge while waiting for the other half of a probable

appointment in that cave. He might have thrown it away then and there

as soon as she turned up, but with that instinctive inhibition which

most of us have against throwing something away with which we have not

completely finished, he took it with him into the cave when the lady

arrived and then, as you say, left it there because he couldn’t be

bothered to take it home again—psychologically speaking, there is a

large difference between throwing a thing away and leaving it behind.

And we know the lady _did_ turn up, dear little Anthony, because

otherwise he wouldn’t have gone into the cave at all, but would have

continued to sit outside where he could see to read. Are you with me?”

“Humph!” said Anthony.

“Now who was the other half of this man’s appointment?” Roger

continued in argumentative tones. “Personally, I’m putting my money on

Mrs. Vane. As far as friend Colin knew nobody but himself and Mrs.

Vane had any inkling about that cave. He discovered it himself, he

told us, about a year ago, and was at once struck with its suitability

for the purpose to which he afterward put it. He was quite positive

that he, at any rate, had told nobody else of its existence. To sum up

then—if Colin is telling the truth all through, Mrs. Vane herself

arranged an appointment with an unknown man belonging to the middle

classes for some time since last Saturday morning, to discuss business

of an obviously secret and confidential nature. And to stretch a

point, we’ll add that that appointment resulted in her death, and that

the unknown middle-class man is her murderer.—And how is all that,”

Roger concluded with legitimate pride, “out of just finding a copy of

_London Opinion_ in that little cave, eh?”

“So now I should think you’d better go off and talk it all over with

Moresby,” said Anthony hopefully.

“Anthony, you disgust me. Do you or do you not want to help me save

your young woman from the gallows? No, don’t trouble to reply to that

question; it’s a rhetorical one. You do. Very well, then. Continue, if

you please, to sustain the part of idiot friend which you play so

admirably.”

“Well, what do you want me to do?” Anthony asked uncomfortably.

“Listen to me while I clarify my own ideas, somewhat nebulous at the

moment, by putting them into speech. Let me go on examining

possibilities. Though by the way, since embarking on this one-sided

discussion I find I appear to have converted myself on one point. I do

_not_ believe it was Colin Woodthorpe who left that copy of _London

Opinion_ in the cave. What have you got to say about that?”

“You made out a pretty useful case against it,” Anthony was forced to

admit.

“Yes; I did. On grounds of pure reason I reject Colin as our unknown

man, but I can easily find that out for certain; I’ve got a little

test in mind for him, which I propose to apply as soon as I leave you.

Well, now, assuming Colin is out of it, can we find anybody else to

take his place? Think hard.”

“Wait a minute, though,” Anthony said after a little pause. “Aren’t

you forgetting those foot-prints? You’ve been saying all the time that

it must have been a woman with Mrs. Vane, not a man. How does that

square in with this idea?”

“No, I’m not forgetting them. They can be worked into this theory all

right. If we assume, you see, that the murder was a premeditated one,

as I think it certainly was, we can assume also that the murderer took

a few elementary precautions to throw the police off his track if ever

anything turned up to make them suspicious about the accident theory.

Well, supposing that Mrs. Vane arrived alone, as we now think she must

have done, what would be easier for the man than to put on a pair of

female shoes he’d brought with him for the purpose, go a little way

along the ledge and then walk back again beside Mrs. Vane’s tracks,

carefully making prints wherever he could and modifying his stride to

suit her smaller steps? That’s perfectly feasible. Footprints and how

to fake them are about the first thing to which your amateur murderer

would turn his attention.”

“Cunning,” commented Anthony.

“Oh, yes; but perfectly intelligible. Well now, having disposed of

that point, let’s get back to where we were before. Can you think of

anyone else to take young Woodthorpe’s place as the villain of the

piece?”

Anthony ruminated. “The only other men in any way mixed up in the show

seem to be Dr. Vane and Russell.”

“Ye-es. And that doesn’t help us much, does it? Dr. Vane we can wash

out right away; there’s no conceivable reason why a wife should want

to make an appointment in an out-of-the-way and thoroughly

uncomfortable place with her own husband when she can much better

interview him from her own drawing-room sofa. But Russell—! What does

Russell give us?”

“If she _had_ been carrying on an intrigue with him as well as

Woodthorpe,” Anthony murmured.

Roger shifted his position so that he could plunge both his legs in

the water up to their knees. “Ah, that’s better. You’re missing a lot,

Anthony, if you only knew it, by being so proud and superior; superior

people always do.—Yes, that’s perfectly true. Russell would then have

almost exactly the same motive for getting rid of her as Colin had,

wouldn’t he? Jealous wife instead of jealous unknown fiancée (I wonder

who friend Colin _is_ meditating an engagement with, by the way, if

Moresby’s right. It ought to be easy enough to find out), _plus_ fear

of jealous husband’s righteous wrath possibly into the bargain, if

she’d been trying the same bluff on with him too. But that does make

the lady a little—how shall I put it?—_promiscuous_, doesn’t it?”

“I shouldn’t think she’d stick at that,” said Anthony sagely.

“Oh, nor should I. Not for a moment. Especially if she’d got a little

game on with both of them, to her own ultimate advantage. But if that

were the case, I can’t help thinking it somewhat imprudent to meet

them both in the same very compromising spot. _That_ doesn’t sound

like Mrs. Vane at all to me.”

“But she _did_ meet the second man in the same place for all that,”

Anthony pointed out, “whether it was Russell or not.”

“Yes, that’s true enough. Of course, this may have been an isolated

assignation, made with the knowledge that Colin would be busy at that

time elsewhere. But Colin hasn’t an alibi for the time of Mrs. Vane’s

death, we discovered, whereas the inspector says that Russell himself

has, a cast-iron one. No, it’s a pure guess of mine, Anthony, but I

feel instinctively that this mysterious man is somebody who hasn’t

cropped up in the case at all yet.”

“Oh! That’s rather vague. And you haven’t the slightest notion who it

could be?”

“Yes, I have,” Roger replied thoughtfully. “Just the slightest notion.

It’s my opinion that this man will prove to be somebody out of Mrs.

Vane’s murky past. Quite possibly her real husband.”

“By Jove, that’s an idea,” Anthony concurred with enthusiasm. “Good

for you, Roger!”

“Thank you, Anthony,” Roger returned gratefully.

They discussed this interesting possibility for a short time, and then

Roger began to put on his shoes and socks.

“I think that’s really all there is to go into at present,” he said,

“so you can have leave of absence for the rest of the morning. You can

tell Margaret about our discovery last night and this new visitor Mrs.

Vane may have had recently. With any luck she ought to be able to give

us a pointer to the gent.”

Anthony rose to his feet. “If I happen to see her, I will,” he said a

little stiffly.

“‘If I happen to see her, I will!’” Roger scoffed. “Oh, very good,

Anthony; very good indeed. I must try you with the butter test at

lunch. If half-a-pound of butter, placed in the patient’s mouth, shows

no sign of melting within——”

“What are _you_ going to do?” Anthony asked hurriedly.

“Me? Oh, I’ve got to be busy. I’ve got to lay my trap for young Colin

first of all; then I want to have a word with Moresby and hear exactly

what he’s made of that _London Opinion_, if anything (he’s probably

concealing it from me in his breast-pocket at this very moment); and

lastly I want to tackle this business of the mysterious stranger from

the other end. I’m going to cross-examine every inhabitant of the

place within a square mile of that ledge to try and find someone who

was within sight of it early on Tuesday afternoon. I’m convinced I’m

on the right tack; if Margaret can’t help us, I’m going to exhaust the

possibilities of that line of information if it takes me a month.”

“But I thought everybody had been questioned about that already?”

“Not so,” Roger replied cunningly. “They were questioned before about

seeing Mrs. Vane. There was no word mentioned about a strange man.”

“I see,” said Anthony, balancing irresolutely on each foot in turn.

“Yes, that’s a sound scheme.—Well, I’ll be strolling along now, I

think, if you don’t want me any more.”

Roger waved a paternal farewell with an Oxford brogue.

After Anthony had departed Roger did not follow him immediately. For

quite a long time he sat on his rock, oblivious of the fact that other

and even tempting ones were being uncovered by the receding tide

straight in front of him. This talk with Anthony certainly had

clarified his ideas very considerably—had, indeed, presented him with

some highly interesting brand-new ones. The case had suddenly taken on

an entirely different aspect. From being merely complex it had become

downright complicated. He wondered what Inspector Moresby, with his

very much more conventional methods, would have to say about his

deductions from that copy of _London Opinion_, a piece of constructive

reasoning which Roger had not the slightest hesitation in

characterising in his own mind as brilliant.

There are some people who are said to know instinctively whether they

are in the right or wrong, without the aid of any extraneous evidence.

Roger had not the least doubt that he possessed this sixth sense, and

as he rose at last to his feet and began his scramble back to the foot

of the cliffs every instinct was busy telling him that he had got his

finger poised above the very heart of the problem. In some new actor,

not yet appeared on the stage, would the ultimate solution be found.

To lay his hands on him should only prove a matter of time and

patience.

Humming blithely, he clambered up the uneven ascent and hoisted

himself on the ledge. Well, first of all he would have to——

“Ah, _there_ you are, Mr. Sheringham! Do you know, I had quite an idea

I should find you here. I’ve been so anxious to see you again, after

our very brief conversation yesterday morning. I want to ask you what

you think of this terrible crime in our midst, and whether you have

formed a theory yet. I hope—I do so hope it will not prove to have

been committed by—ah, dear me, a terrible affair!”

Roger wheeled about. From above a boulder at the back of the ledge a

face like that of a benign and beardless goat was regarding him

benevolently through an enormous pair of horn-rimmed spectacles.

“Oh, hell!” confided Roger Sheringham to his immortal soul.
