"Of course. He is the assassin, and has implicated Herries by placing in his room, the razor, the key and the pocket-book. This unknown man must have been the one whom Sir Simon expected on the previous night."
"How do you know that?"
"Because, by your own showing, Sir Simon could not have known of his nephew's presence here. The unknown man did not arrive at the time he was expected, but when the inn was closed, he must either have been admitted by Sir Simon, and taken to the bedroom, or he must have got in by the window."
"The window is on the first floor!"
Browne cast a look upward at the low ceiling.
"I don't think an active man would have any difficulty in climbing."
"There is certainly some trellis work outside, against the window of the room Sir Simon occupied," said Trent half to himself, "but this is all theoretical."
"So is the evidence against Herries."
"Do you call a razor, a stained shirt, the dead man's pocket-book and the key of the dead man's room, theoretical?"
"These things were placed in Herries' room by the assassin to implicate him in the crime," said Browne obstinately.
