“I examined the ground carefully in the hope of finding it,” said the Inspector.
“It was torn out of the dead man’s hand. Why was someone so anxious to get possession of it? Because it incriminated him. And what would he do with it? Thrust it into his pocket, most likely, never noticing that a corner of it had been left in the grip of the corpse. If we could get the rest of that sheet it is obvious that we should have gone a long way towards solving the mystery.”
“Yes, but how can we get at the criminal’s pocket before we catch the criminal?”
“Well, well, it was worth thinking over. Then there is another obvious point. The note was sent to William. The man who wrote it could not have taken it; otherwise, of course, he might have delivered his own message by word of mouth. Who brought the note, then? Or did it come through the post?”
“I have made inquiries,” said the Inspector. “William received a letter by the afternoon post yesterday. The envelope was destroyed by him.”
“Excellent!” cried Holmes, clapping the Inspector on the back. “You’ve seen the postman. It is a pleasure to work with you. Well, here is the lodge, and if you will come up, Colonel, I will show you the scene of the crime.”
We passed the pretty cottage where the murdered man had lived, and walked up an oak-lined avenue to the fine old Queen Anne house, which bears the date of Malplaquet upon the lintel of the door. Holmes and the Inspector led us round it until we came to the side gate, which is separated by a stretch of garden from the hedge which lines the road. A constable was standing at the kitchen door.
