<h2><SPAN name="chap22"></SPAN>CHAPTER XXII.<br/> Mr. Beverley Moves On</h2>
<p>“Good Lord!” said Bill, as he put down the letter.</p>
<p>“I thought you’d say that,” murmured Antony.</p>
<p>“Tony, do you mean to say that you knew all this?”</p>
<p>“I guessed some of it. I didn’t quite know all of it, of
course.”</p>
<p>“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?”</p>
<p>“Yes.”</p>
<p>“What did you say? That you’d discovered that Mark was
Robert?”</p>
<p>“Yes. At least I said that this morning I should probably telegraph to
Mr. Cartwright of Wimpole Street, and ask him to—”</p>
<p>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.”</p>
<p>Antony laughed and apologized.</p>
<p>“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.”</p>
<p>“But whatever made you think of a dentist for that?”</p>
<p>“Who could do it better? Could <i>you</i> 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.”</p>
<p>Bill nodded thoughtfully and went back again to the letter.</p>
<p>“I see. And you told Cayley that you were telegraphing to Cartwright to
identify the body?”</p>
<p>“Yes. And then of course it was all up for him. Once we knew that Robert
was Mark we knew everything.”</p>
<p>“How <i>did</i> you know?”</p>
<p>Antony got up from the breakfast table and began to fill his pipe.</p>
<p>“I’m not sure that I can say, Bill. You know those problems in
Algebra where you say, ‘Let <i>x</i> be the answer,’ and then you
work it out and find what <i>x</i> 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?”</p>
<p>Bill handed him a box, and he lit his pipe.</p>
<p>“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.”</p>
<p>Antony laughed and took them out of his pocket.</p>
<p>“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.”</p>
<p>“Yes?”</p>
<p>“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?”</p>
<p>“It was the one in the linen-basket?”</p>
<p>“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?”</p>
<p>“Absolutely,” said Bill with conviction.</p>
<p>“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.”</p>
<p>“Go on,” said Bill eagerly.</p>
<p>“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.”</p>
<p>“And the answer was that a murder was intended, even before Robert
arrived?”</p>
<p>“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.”</p>
<p>“You never said anything about them,” complained Bill.</p>
<p>“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!”</p>
<p>“Go on,” said Bill.</p>
<p>“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?”</p>
<p>“When was this?” interrupted Bill. “Just after the
inquest—after you’d seen Amos and Parsons, of course?”</p>
<p>“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.”</p>
<p>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.</p>
<p>“Yes,” said Bill thoughtfully. “Yes.... But wait a moment.
What about the ‘Plough and Horses’?” Antony looked comically
at him.</p>
<p>“You’ll never forgive me, Bill,” he said. “You’ll
never come clue-hunting with me again.”</p>
<p>“What do you mean?”</p>
<p>Antony sighed.</p>
<p>“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 <i>had</i> to be alone
just then. So—” he smiled and added, “Well, I knew you wanted
a drink.”</p>
<p>“You <i>are</i> a devil,” said Bill, staring at him. “And
your interest when I told you that a woman had been staying there—”</p>
<p>“Well, it was only polite to be interested when you’d taken so much
trouble.”</p>
<p>“You brute! You—you Sherlock! And then you keep trying to steal my
matches. Well, go on.”</p>
<p>“That’s all. My <i>x</i> fitted.”</p>
<p>“Did you guess Miss Norris and all that?”</p>
<p>“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.”</p>
<p>Bill was silent for a long time. Then, puffing at his pipe, he said slowly,
“Has Cayley shot himself?”</p>
<p>Antony shrugged his shoulders.</p>
<p>“Poor devil,” said Bill. “It was decent of you to give him a
chance. I’m glad you did.”</p>
<p>“I couldn’t help liking Cayley in a kind of way, you know.”</p>
<p>“He’s a clever devil. If you hadn’t turned up just when you
did, he would never have been found out.”</p>
<p>“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 <i>how</i> he killed Mark,
but I think it would have become obvious sooner or later that he <i>had</i>
killed him.”</p>
<p>“Yes, there’s something in that.... Oh, just tell me one thing. Why
did Mark tell Miss Norbury about his imaginary brother?”</p>
<p>“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.”</p>
<p>“Are you going to tell the police?”</p>
<p>“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.”</p>
<p>“I asked,” explained Bill, “because I was wondering what I
should say to—to Betty. Miss Calladine. You see, she’s bound to
ask.”</p>
<p>“Perhaps you won’t see her again for a long, long time,” said
Antony sadly.</p>
<p>“As a matter of fact, I happen to know that she will be at the
Barringtons. And I go up there to-morrow.”</p>
<p>“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.”</p>
<p>“Righto!”</p>
<p>Antony knocked the ashes out of his pipe and got up.</p>
<p>“The Barringtons,” he said. “Large party?”</p>
<p>“Fairly, I think.”</p>
<p>Antony smiled at his friend.</p>
<p>“Yes. Well, if any of ’em <i>should</i> happen to be murdered, you
might send for me. I’m just getting into the swing of it.”</p>
