<h2><SPAN name="chap13"></SPAN>CHAPTER XIII.<br/> The Open Window</h2>
<p>Anthony’s first thought was that Cayley had hidden something; something,
perhaps, which he had found by the body, and—but that was absurd. In the
time at his disposal, he could have done no more than put it away in a drawer,
where it would be much more open to discovery by Antony than if he had kept it
in his pocket. In any case he would have removed it by this time, and hidden it
in some more secret place. Besides, why in this case bother about shutting the
door?</p>
<p>Bill pulled open a drawer in the chest, and looked inside.</p>
<p>“Is it any good going through these, do you think?” he asked.</p>
<p>Antony looked over his shoulder.</p>
<p>“Why did he keep clothes here at all?” he asked. “Did he ever
change down here?”</p>
<p>“My dear Tony, he had more clothes than anybody in the world. He just
kept them here in case they might be useful, I expect. When you and I go from
London to the country we carry our clothes about with us. Mark never did. In
his flat in London he had everything all over again which he has here. It was a
hobby with him, collecting clothes. If he’d had half a dozen houses, they
would all have been full of a complete gentleman’s town and country
outfit.”</p>
<p>“I see.”</p>
<p>“Of course, it might be useful sometimes, when he was busy in the next
room, not to have to go upstairs for a handkerchief or a more comfortable
coat.”</p>
<p>“I see. Yes.” He was walking round the room as he answered, and he
lifted the top of the linen basket which stood near the wash basin and glanced
in. “He seems to have come in here for a collar lately.”</p>
<p>Bill peered in. There was one collar at the bottom of the basket.</p>
<p>“Yes. I daresay he would,” he agreed. “If he suddenly found
that the one he was wearing was uncomfortable or a little bit dirty, or
something. He was very finicking.”</p>
<p>Antony leant over and picked it out.</p>
<p>“It must have been uncomfortable this time,” he said, after
examining it carefully. “It couldn’t very well be cleaner.”
He dropped it back again. “Anyway, he did come in here sometimes?”</p>
<p>“Oh, yes, rather.”</p>
<p>“Yes, but what did Cayley come in for so secretly?”</p>
<p>“What did he want to shut the door for?” said Bill.
“That’s what I don’t understand. You couldn’t have seen
him, anyhow.”</p>
<p>“No. So it follows that I might have heard him. He was going to do
something which he didn’t want me to hear.”</p>
<p>“By Jove, that’s it!” said Bill eagerly.</p>
<p>“Yes; but what?”</p>
<p>Bill frowned hopefully to himself, but no inspiration came.</p>
<p>“Well, let’s have some air, anyway,” he said at last,
exhausted by the effort, and he went to the window, opened it, and looked out.
Then, struck by an idea, he turned back to Antony and said, “Do you think
I had better go up to the pond to make sure that they’re still at it?
Because—”</p>
<p>He broke off suddenly at the sight of Antony’s face.</p>
<p>“Oh, idiot, idiot!” Antony cried. “Oh, most super-excellent
of Watsons! Oh, you lamb, you blessing! Oh, Gillingham, you incomparable
ass!”</p>
<p>“What on earth—”</p>
<p>“The window, the window!” cried Antony, pointing to it.</p>
<p>Bill turned back to the window, expecting it to say something. As it said
nothing, he looked at Antony again.</p>
<p>“He was opening the window!” cried Antony.</p>
<p>“Who?”</p>
<p>“Cayley, of course.” Very gravely and slowly he expounded.
“He came in here in order to open the window. He shut the door so that I
shouldn’t hear him open the window. He opened the window. I came in here
and found the window open. I said, ‘This window is open. My amazing
powers of analysis tell me that the murderer must have escaped by this
window.’ ‘Oh,’ said Cayley, raising his eyebrows.
‘Well,’ said he, ‘I suppose you must be right.’ Said I
proudly, ‘I am. For the window is open,’ I said. Oh, you
incomparable ass!”</p>
<p>He understood now. It explained so much that had been puzzling him.</p>
<p>He tried to put himself in Cayley’s place—Cayley, when Antony had
first discovered him, hammering at the door and crying, “Let me
in!” Whatever had happened inside the office, whoever had killed Robert,
Cayley knew all about it, and knew that Mark was not inside, and had not
escaped by the window. But it was necessary to Cayley’s plans—to
Mark’s plans if they were acting in concert—that he should be
thought so to have escaped. At some time, then, while he was hammering (the key
in his pocket) at the locked door, he must suddenly have remembered—with
what a shock!—that a mistake had been made. A window had not been left
open!</p>
<p>Probably it would just have been a horrible doubt at first. <i>Was</i> the
office window open? Surely it was open! <i>Was</i> it?.... Would he have time
now to unlock the door, slip in, open the French windows and slip out again?
No. At any moment the servants might come. It was too risky. Fatal, if he were
discovered. But servants were stupid. He could get the windows safely open
while they were crowding round the body. They wouldn’t notice. He could
do it somehow.</p>
<p>And then Antony’s sudden appearance! Here was a complication. And Antony
suggesting that they should try the window! Why, the window was just what he
wanted to avoid. No wonder he had seemed dazed at first.</p>
<p>Ah, and here at last was the explanation why they had gone the longest way
round and yet <i>run</i>. It was Cayley’s only chance of getting a start
on Antony, of getting to the windows first, of working them open somehow before
Antony caught him up. Even if that were impossible, he must get there first,
just to make sure. Perhaps they <i>were</i> open. He must get away from Antony
and see. And if they were shut, hopelessly shut, then he must have a moment to
himself, a moment in which to think of some other plan, and avoid the ruin
which seemed so suddenly to be threatening.</p>
<p>So he had run. But Antony had kept up with him. They had broken in the window
together, and gone into the office. But Cayley was not done yet. There was the
dressing-room window! But quietly, quietly. Antony mustn’t hear.</p>
<p>And Antony didn’t hear. Indeed, he had played up to Cayley splendidly.
Not only had he called attention to the open window, but he had carefully
explained to Cayley why Mark had chosen this particular window in preference to
the office window. And Cayley had agreed that probably that was the reason. How
he must have chuckled to himself! But he was still a little afraid. Afraid that
Antony would examine the shrubbery. Why? Obviously because there was no trace
of anyone having broken through the shrubbery. No doubt Cayley had provided the
necessary traces since, and had helped the Inspector to find them. Had he even
gone as far as footmarks—in Mark’s shoes? But the ground was very
hard. Perhaps footmarks were not necessary. Antony smiled as he thought of the
big Cayley trying to squeeze into the dapper little Mark’s shoes. Cayley
must have been glad that footmarks were not necessary.</p>
<p>No, the open window was enough; the open window and a broken twig or two. But
quietly, quietly. Antony mustn’t hear. And Antony had not heard.... But
he had seen a shadow on the wall.</p>
<p>They were outside on the lawn again now, Bill and Antony, and Bill was
listening open-mouthed to his friend’s theory of yesterday’s
happenings. It fitted in, it explained things, but it did not get them any
further. It only gave them another mystery to solve.</p>
<p>“What’s that?” said Antony.</p>
<p>“Mark. Where’s Mark? If he never went into the office at all, then
where is he now?”</p>
<p>“I don’t say that he never went into the office. In fact, he must
have gone. Elsie heard him.” He stopped and repeated slowly, “She
heard him—at least she says she did. But if he was there, he came out
again by the door.”</p>
<p>“Well, but where does that lead you?”</p>
<p>“Where it led Mark. The passage.”</p>
<p>“Do you mean that he’s been hiding there all the time?”
Antony was silent until Bill had repeated his question, and then with an effort
he came out of his thoughts and answered him.</p>
<p>“I don’t know. But look here. Here is a possible explanation. I
don’t know if it is the right one—I don’t know, Bill;
I’m rather frightened. Frightened of what may have happened, of what may
be going to happen. However, here is an explanation. See if you can find any
fault with it.”</p>
<p>With his legs stretched out and his hands deep in his pockets, he lay back on
the garden-seat, looking up to the blue summer sky above him, and just as if he
saw up there the events of yesterday being enacted over again, he described
them slowly to Bill as they happened.</p>
<p>“We’ll begin at the moment when Mark shoots Robert. Call it an
accident; probably it was. Mark would say it was, anyhow. He is in a panic,
naturally. But he doesn’t lock the door and run away. For one thing, the
key is on the outside of the door; for another, he is not quite such a fool as
that. But he is in a horrible position. He is known to be on bad terms with his
brother; he has just uttered some foolish threat to him, which may possibly
have been overheard. What is he to do? He does the natural thing, the thing
which Mark would always do in such circumstances. He consults Cayley, the
invaluable, inevitable Cayley.</p>
<p>“Cayley is just outside, Cayley must have heard the shot, Cayley will
tell him what to do. He opens the door just as Cayley is coming to see what is
the matter. He explains rapidly. ‘What’s to be done, Cay?
What’s to be done? It was an accident. I swear it was an accident. He
threatened me. He would have shot me if I hadn’t. Think of something,
quick!’</p>
<p>“Cayley has thought of something. ‘Leave it to me,’ he says.
‘You clear out altogether. <i>I</i> shot him, if you like. I’ll do
all the explaining. Get away. Hide. Nobody saw you go in. Into the passage,
quick. I’ll come to you there as soon as I can.’</p>
<p>“Good Cayley. Faithful Cayley! Mark’s courage comes back. Cayley
will explain all right. Cayley will tell the servants that it was an accident.
He will ring up the police. Nobody will suspect Cayley—Cayley has no
quarrel with Robert. And then Cayley will come into the passage and tell him
that it is all right, and Mark will go out by the other end, and saunter slowly
back to the house. He will be told the news by one of the servants. Robert
accidentally shot? Good Heavens!</p>
<p>“So, greatly reassured, Mark goes into the library. And Cayley goes to
the door of the office.... and locks it. And then he bangs on the door and
shouts, ‘Let me in!’”</p>
<p>Antony was silent. Bill looked at him and shook his head.</p>
<p>“Yes, Tony, but that doesn’t make sense. What’s the point of
Cayley behaving like that?”</p>
<p>Antony shrugged his shoulders without answering.</p>
<p>“And what has happened to Mark since?”</p>
<p>Antony shrugged his shoulders again.</p>
<p>“Well, the sooner we go into that passage, the better,” said Bill.</p>
<p>“You’re ready to go?”</p>
<p>“Quite,” said Bill, surprised.</p>
<p>“You’re quite ready for what we may find?”</p>
<p>“You’re being dashed mysterious, old boy.”</p>
<p>“I know I am.” He gave a little laugh, and went on, “Perhaps
I’m being an ass, just a melodramatic ass. Well, I hope I am.” He
looked at his watch.</p>
<p>“It’s safe, is it? They’re still busy at the pond?”</p>
<p>“We’d better make certain. Could you be a sleuthhound,
Bill—one of those that travel on their stomachs very noiselessly? I mean,
could you get near enough to the pond to make sure that Cayley is still there,
without letting him see you?”</p>
<p>“Rather!” He got up eagerly. “You wait.”</p>
<p>Antony’s head shot up suddenly. “Why, that was what Mark
said,” he cried.</p>
<p>“Mark?”</p>
<p>“Yes. What Elsie heard him say.”</p>
<p>“Oh, that.”</p>
<p>“Yes I suppose she couldn’t have made a mistake, Bill? She did hear
him?”</p>
<p>“She couldn’t have mistaken his voice, if that’s what you
mean.”</p>
<p>“Oh?”</p>
<p>“Mark had an extraordinary characteristic voice.”</p>
<p>“Oh!”</p>
<p>“Rather high-pitched, you know, and—well, one can’t explain,
but——”</p>
<p>“Yes?”</p>
<p>“Well, rather like this, you know, or even more so if anything.” He
rattled these words off in Mark’s rather monotonous, high-pitched voice,
and then laughed, and added in his natural voice, “I say, that was really
rather good.”</p>
<p>Antony nodded quickly. “That was like it?” he said.</p>
<p>“Exactly.”</p>
<p>“Yes.” He got up and squeezed Bill’s arm. “Well just go
and see about Cayley, and then we’ll get moving. I shall be in the
library.”</p>
<p>“Right.”</p>
<p>Bill nodded and walked off in the direction of the pond. This was glorious fun;
this was life. The immediate programme could hardly be bettered. First of all
he was going to stalk Cayley. There was a little copse above the level of the
pond, and about a hundred yards away from it. He would come into this from the
back, creep cautiously through it, taking care that no twigs cracked, and then,
drawing himself on his stomach to the edge, peer down upon the scene below him.
People were always doing that sort of thing in books, and he had been filled
with a hopeless envy of them; well, now he was actually going to do it himself.
What fun!</p>
<p>And then, when he had got back unobserved to the house and reported to Antony,
they were going to explore the secret passage! Again, what fun! Unfortunately
there seemed to be no chance of buried treasure, but there might be buried
clues. Even if you found nothing, you couldn’t get away from the fact
that a secret passage was a secret passage, and anything might happen in it.
But even that wasn’t the end of this exciting day. They were going to
watch the pond that night; they were going to watch Cayley under the moonlight,
watch him as he threw into the silence of the pond—what? The revolver?
Well, anyhow, they were going to watch him. What fun!</p>
<p>To Antony, who was older and who realized into what deep waters they were
getting, it did not seem fun. But it was amazingly interesting. He saw so much,
and yet somehow it was all out of focus. It was like looking at an opal, and
discovering with every movement of it some new colour, some new gleam of light
reflected, and yet never really seeing the opal as a whole. He was too near it,
or too far away; he strained his eyes and he relaxed his eyes; it was no good.
His brain could not get hold of it.</p>
<p>But there were moments when he almost had it.... and then turned away from it.
He had seen more of life than Bill, but he had never seen murder before, and
this which was in his mind now, and to which he was afraid to listen, was not
just the hot-blooded killing which any man may come to if he lose control. It
was something much more horrible. Too horrible to be true. Then let him look
again for the truth. He looked again—but it was all out of focus.</p>
<p>“I will <i>not</i> look again,” he said aloud, as he began to walk
towards the house. “Not yet, anyway.” He would go on collecting
facts and impressions. Perhaps the one fact would come along, by itself which
would make everything clear.</p>
