Mr. Wetherell rang the bell, and a moment later it was answered by the man himself.
"Come in, James, and shut the door behind you," his master said.
The man did as he was ordered, but not without looking, as I thought, a little uncomfortable. The Inspector I could see had noticed this too, for he had been watching him intently ever since he had appeared in the room.

"To begin with," said the Inspector, "I want you to look at this envelope. Have you seen it before?"
He handed him the envelope of the anonymous letter addressed to Mr. Wetherell. The man took it and turned it over in his hands.
"Yes, sir," he said, "I have seen it before; I took it in at the front door."
"From whom?"
"From a little old woman, sir," the man answered.
"A little old woman!" cried the Inspector, evidently surprised. "What sort of woman?"
