You will let me have their names and addresses in case I want to
communicate with them?"

"Of course. One of them is staying on, if you would like to see him
later, but they only came back from their golf as we crossed the hall."

"That's all right, Mr. Cayley. Well, now then, let's go back to three
o'clock. Where were you when Robert arrived?"

Cayley explained how he had been sitting in the hall, how Audrey had
asked him where the master was, and how he had said that he had last
seen him going up to the Temple.

"She went away, and I went on with my book. There was a step on the
stairs, and I looked up to see Mark coming down. He went into the
office, and I went on with my book again. I went into the library for
a moment, to refer to another book, and when I was in there I heard a
shot. At least, it was a loud bang, I wasn't sure if it was a shot. I
stood and listened. Then I came slowly to the door and looked out. Then
I went back again, hesitated a bit, you know, and finally decided to go
across to the office, and make sure that it was all right. I turned the
handle of the door and found it was locked. Then I got frightened, and I

gone up to his room, without your seeing him?"

"There are back stairs. He wouldn't have used them in the ordinary way,
of course. But I wasn't in the hall all the afternoon. He might easily
have gone upstairs without my knowing anything about it."

"So that you weren't surprised when you saw him coming down?"

"Oh, not a bit."

"Well, did he say anything?"

"He said, 'Robert's here?' or something of the sort. I suppose he'd
heard the bell, or the voices in the hall."

"Which way does his bedroom face? Could he have seen him coming down the
drive?"

"He might have, yes."

"Well?"

"Well, then, I said 'Yes,' and he gave a sort of shrug, and said, 'Don't
go too far away, I might want you'; and then went in."

"What did you think he meant by that?"

"Well, he consults me a good deal, you know. I'm his sort of unofficial
solicitor in a kind of way."

"This was a business meeting rather than a brotherly one?"

"Oh, yes. That's how he regarded it, I'm sur
