CHAPTER XXII.

Mr. Beverley Moves On

“Good Lord!” said Bill, as he put down the letter.

“I thought you’d say that,” murmured Antony.

“Tony, do you mean to say that you knew all this?”

“I guessed some of it. I didn’t quite know all of it, of course.”

“Good Lord!” said Bill again, and returned to the letter. In a moment

he was looking up again. “What did you write to him? Was that last

night? After I’d gone into Stanton?”

“Yes.”

“What did you say? That you’d discovered that Mark was Robert?”

“Yes. At least I said that this morning I should probably telegraph to

Mr. Cartwright of Wimpole Street, and ask him to—”

Bill burst in eagerly on the top of the sentence. “Yes, now what was

all that about? You were so damn Sherlocky yesterday all of a sudden.

We’d been doing the thing together all the time, and you’d been telling

me everything, and then suddenly you become very mysterious and private

and talk enigmatically—is that the word?—about dentists and swimming

and the ‘Plough and Horses,’ and—well, what was it all about? You

simply vanished out of sight; I didn’t know what on earth we were

talking about.”

Antony laughed and apologized.

“Sorry, Bill. I felt like that suddenly. Just for the last half-hour;

just to end up with. I’ll tell you everything now. Not that there’s

anything to tell, really. It seems so easy when you know it—so obvious.

About Mr. Cartwright of Wimpole Street. Of course he was just to

identify the body.”

“But whatever made you think of a dentist for that?”

“Who could do it better? Could _you_ have done it? How could you? You’d

never gone bathing with Mark; you’d never seen him stripped. He didn’t

swim. Could his doctor do it? Not unless he’d had some particular

operation, and perhaps not then. But his dentist could—at any time,

always—if he had been to his dentist fairly often. Hence Mr. Cartwright

of Wimpole Street.”

Bill nodded thoughtfully and went back again to the letter.

“I see. And you told Cayley that you were telegraphing to Cartwright to

identify the body?”

“Yes. And then of course it was all up for him. Once we knew that

Robert was Mark we knew everything.”

“How _did_ you know?”

Antony got up from the breakfast table and began to fill his pipe.

“I’m not sure that I can say, Bill. You know those problems in Algebra

where you say, ‘Let _x_ be the answer,’ and then you work it out and

find what _x_ is. Well, that’s one way; and another way, which they

never give you any marks for at school, is to guess the answer. Pretend

the answer is 4—well, will that satisfy the conditions of the problem?

No. Then try 6; and if 6 doesn’t either, then what about 5?—and so on.

Well, the Inspector and the Coroner and all that lot had guessed their

answer, and it seemed to fit, but you and I knew it didn’t really fit;

there were several conditions in the problem which it didn’t fit at

all. So we knew that their answer was wrong, and we had to think of

another—an answer which explained all the things which were puzzling

us. Well, I happened to guess the right one. Got a match?”

Bill handed him a box, and he lit his pipe.

“Yes, but that doesn’t quite do, old boy. Something must have put you

on to it suddenly. By the way, I’ll have my matches back, if you don’t

mind.”

Antony laughed and took them out of his pocket.

“Sorry.... Well then, let’s see if I can go through my own mind again,

and tell you how I guessed it. First of all, the clothes.”

“Yes?”

“To Cayley the clothes seemed an enormously important clue. I didn’t

quite see why, but I did realize that to a man in Cayley’s position the

smallest clue would have an entirely disproportionate value. For some

reason, then, Cayley attached this exaggerated importance to the

clothes which Mark was wearing on that Tuesday morning; all the

clothes, the inside ones as well as the outside ones. I didn’t know

why, but I did feel certain that, in that case, the absence of the

collar was unintentional. In collecting the clothes he had overlooked

the collar. Why?”

“It was the one in the linen-basket?”

“Yes. It seemed probable. Why had Cayley put it there? The obvious

answer was that he hadn’t. Mark had put it there. I remembered what you

told me about Mark being finicky, and having lots of clothes and so on,

and I felt that he was just the sort of man who would never wear the

same collar twice.” He paused, and then asked, “Is that right, do you

think?”

“Absolutely,” said Bill with conviction.

“Well, I guessed it was. So then I began to see an x which would fit

just this part of the problem—the clothes part. I saw Mark changing his

clothes; I saw him instinctively dropping the collar in the

linen-basket, just as he had always dropped every collar he had ever

taken off, but leaving the rest of the clothes on a chair in the

ordinary way; and I saw Cayley collecting all the clothes

afterwards—all the visible clothes—and not realizing that the collar

wasn’t there.”

“Go on,” said Bill eagerly.

“Well, I felt pretty sure about that, and I wanted an explanation of

it. Why had Mark changed down there instead of in his bedroom? The only

answer was that the fact of his changing had to be kept secret. When

did he change? The only possible time was between lunch (when he would

be seen by the servants) and the moment of Robert’s arrival. And when

did Cayley collect the clothes in a bundle? Again, the only answer was

‘Before Robert’s arrival.’ So another x was wanted—to fit those three

conditions.”

“And the answer was that a murder was intended, even before Robert

arrived?”

“Yes. Well now, it couldn’t be intended on the strength of that letter,

unless there was very much more behind the letter than we knew. Nor was

it possible a murder could be intended without any more preparation

than the changing into a different suit in which to escape. The thing

was too childish. Also, if Robert was to be murdered, why go out of the

way to announce his existence to you all—even, at the cost of some

trouble, to Mrs. Norbury? What did it all mean? I didn’t know. But I

began to feel now that Robert was an incident only; that the plot was a

plot of Cayley’s against Mark—either to get him to kill his brother, or

to get his brother to kill him—and that for some inexplicable reason

Mark seemed to be lending himself to the plot.” He was silent for a

little, and then said, almost to himself, “I had seen the empty brandy

bottles in that cupboard.”

“You never said anything about them,” complained Bill.

“I only saw them afterwards. I was looking for the collar, you

remember. They came back to me afterwards; I knew how Cayley would feel

about it.... Poor devil!”

“Go on,” said Bill.

“Well, then, we had the inquest, and of course I noticed, and I suppose

you did too, the curious fact that Robert had asked his way at the

second lodge and not at the first. So I talked to Amos and Parsons.

That made it more curious. Amos told me that Robert had gone out of his

way to speak to him; had called to him, in fact. Parsons told me that

his wife was out in their little garden at the first lodge all the

afternoon, and was certain that Robert had never come past it. He also

told me that Cayley had put him on to a job on the front lawn that

afternoon. So I had another guess. Robert had used the secret

passage—the passage which comes out into the park between the first and

second lodges. Robert, then, had been in the house; it was a put-up job

between Robert and Cayley. But how could Robert be there without Mark

knowing? Obviously, Mark knew too. What did it all mean?”

“When was this?” interrupted Bill. “Just after the inquest—after you’d

seen Amos and Parsons, of course?”

“Yes. I got up and left them, and came to look for you. I’d got back to

the clothes then. Why did Mark change his clothes so secretly?

Disguise? But then what about his face? That was much more important

than clothes. His face, his beard—he’d have to shave off his beard—and

then—oh, idiot! I saw you looking at that poster. Mark acting, Mark

made-up, Mark disguised. Oh, priceless idiot! Mark was Robert....

Matches, please.”

Bill passed over the matches again, waited till Antony had relit his

pipe, and then held out his hand for them, just as they were going into

the other’s pocket.

“Yes,” said Bill thoughtfully. “Yes.... But wait a moment. What about

the ‘Plough and Horses’?” Antony looked comically at him.

“You’ll never forgive me, Bill,” he said. “You’ll never come

clue-hunting with me again.”

“What do you mean?”

Antony sighed.

“It was a fake, Watson. I wanted you out of the way. I wanted to be

alone. I’d guessed at my x, and I wanted to test it—to test it every

way, by everything we’d discovered. I simply _had_ to be alone just

then. So—” he smiled and added, “Well, I knew you wanted a drink.”

“You _are_ a devil,” said Bill, staring at him. “And your interest when

I told you that a woman had been staying there—”

“Well, it was only polite to be interested when you’d taken so much

trouble.”

“You brute! You—you Sherlock! And then you keep trying to steal my

matches. Well, go on.”

“That’s all. My _x_ fitted.”

“Did you guess Miss Norris and all that?”

“Well, not quite. I didn’t realize that Cayley had worked for it from

the beginning—had put Miss Norris up to frightening Mark. I thought

he’d just seized the opportunity.”

Bill was silent for a long time. Then, puffing at his pipe, he said

slowly, “Has Cayley shot himself?”

Antony shrugged his shoulders.

“Poor devil,” said Bill. “It was decent of you to give him a chance.

I’m glad you did.”

“I couldn’t help liking Cayley in a kind of way, you know.”

“He’s a clever devil. If you hadn’t turned up just when you did, he

would never have been found out.”

“I wonder. It was ingenious, but it’s often the ingenious thing which

gets found out. The awkward thing from Cayley’s point of view was that,

though Mark was missing, neither he nor his body could ever be found.

Well, that doesn’t often happen with a missing man. He generally gets

discovered in the end; a professional criminal; perhaps not—but an

amateur like Mark! He might have kept the secret of _how_ he killed

Mark, but I think it would have become obvious sooner or later that he

_had_ killed him.”

“Yes, there’s something in that.... Oh, just tell me one thing. Why did

Mark tell Miss Norbury about his imaginary brother?”

“That’s puzzled me rather, too, Bill. It may be that he was just doing

the Othello business—painting himself black all over. I mean he may

have been so full of his appearance as Robert that he had almost got to

believe in Robert, and had to tell everybody. More likely, though, he

felt that, having told all of you at the house, he had better tell Miss

Norbury, in case she met one of you; in which case, if you mentioned

the approaching arrival of Robert, she might say, ‘Oh, I’m certain he

has no brother; he would have told me if he had,’ and so spoil his

joke. Possibly, too, Cayley put him on to it; Cayley obviously wanted

as many people as possible to know about Robert.”

“Are you going to tell the police?”

“Yes, I suppose they’ll have to know. Cayley may have left another

confession. I hope he won’t give me away; you see, I’ve been a sort of

accessory since yesterday evening. And I must go and see Miss Norbury.”

“I asked,” explained Bill, “because I was wondering what I should say

to—to Betty. Miss Calladine. You see, she’s bound to ask.”

“Perhaps you won’t see her again for a long, long time,” said Antony

sadly.

“As a matter of fact, I happen to know that she will be at the

Barringtons. And I go up there to-morrow.”

“Well, you had better tell her. You’re obviously longing to. Only don’t

let her say anything for a day or two. I’ll write to you.”

“Righto!”

Antony knocked the ashes out of his pipe and got up.

“The Barringtons,” he said. “Large party?”

“Fairly, I think.”

Antony smiled at his friend.

“Yes. Well, if any of ’em _should_ happen to be murdered, you might

send for me. I’m just getting into the swing of it.”
