"We haven't got the envelope, unfortunately."

"And you think that he got this letter on Monday."

"I'm inclined to think so, Bill. Anyhow, I think--I feel almost
certain--that he knew on Monday that his brother was coming."

"Is that going to help us much?"

"No. It makes it more difficult. There's something rather
uncanny about it all. I don't understand it." He was silent for
a little, and then added, "I wonder if the inquest is going to
help us.

"What about last night? I'm longing to hear what you make of
that. Have you been thinking it out at all?"

"Last night," said Antony thoughtfully to himself. "Yes, last
night wants some explaining."

Bill waited hopefully for him to explain. What, for instance,
had Antony been looking for in the cupboard?

"I think," began Antony slowly, "that after last night we must
give up the idea that Mark has been killed; killed, I mean, by
Cayley. I don't believe anybody would go to so much trouble to
hide a suit of clothes when he had a body on his hands. The body
would seem so much more important. I think we may take it now
that the clothes are all that Cayley had to hide."
