“Oh, I just wanted to test an idea. Let me see.” He thought rapidly. “It was pushed under your door or something, I suppose?”
“Oh, no. It came by post.”
“Did it?” said Roger eagerly. “You didn’t notice the postmark, did you?”
“As a matter of fact I did. It seemed so funny that he should have taken the trouble to post it. It was posted from the village by the eight-thirty post that morning.”
“The village, was it? Oh! And was it typewritten?”
“Yes.”
Roger held his breath again. “Was the signature written or typewritten?”
Mrs. Plant considered.
“It was typewritten, as far as I remember.”
“Are you sure of that?” Roger asked eagerly.
