"Oh, I think nothing. It was to Silver's interest that Pine should live, so I don't fancy he set the trap. It was to Chaldea's interest that Pine should not live, since she loves you, and I don't think she is to blame. Garvington couldn't have done it, as he has lost a good friend in Pine, and—and—go on Lambert, suggest some one else."
"I can't. And two out of three you mention were inside The Manor when the second shot was fired, so can prove an alibi."
"I'm not bothering about who fired the second shot," said Miss Greeby leisurely, "but as to who wrote that letter. Once we find the forger, we'll soon discover the assassin."
"True; but how are you going about it?"
"I shall see Silver and force him to give me the letter."
"If you can."
"Oh, I'll manage somehow. The little beast's a coward, and I'll bully him into compliance." Miss Greeby spoke very confidently. "Then we'll see the kind of paper the letter is written on, and there may be an envelope which would show where it was posted. Of course, the forger must be well acquainted with Agnes's handwriting."
"That's obvious," said Lambert promptly. "Well, I suppose that your way of starting the matter is the best. But we have only four days before Silver makes his move."
"When I get the letter he won't make any move," reported Miss Greeby, and she looked very determined.
"Let us hope so. But, Clara, before you return to town I wish you would see Mother Cockleshell."
