"Then we had a look at this poor fellow's mother. We could get no information from her, however, as she is very old and feeble." "And what is the result of your investigations?" "The conviction that the crime is a very peculiar one. Perhaps our visit now may do something to make it less obscure. I think that we are both agreed, Inspector, that the fragment of paper in the dead man's hand, bearing, as it does, the very hour of his death written upon it, is of extreme importance." "It should give a clue, Mr. Holmes." "It _does_ give a clue. Whoever wrote that note was the man who brought William Kirwan out of his bed at that hour. But where is the rest of that sheet of paper?" "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. "Throw the door open, officer," said Holmes. "Now it was on those stairs that young Mr. Cunningham stood and saw the two men struggling just where we are. Old Mr. Cunningham was at that window--the second on the left--and he saw the fellow get away just to the left of that bush. So did the son. They are both sure of it, on account of the bush. Then Mister Alec ran out and knelt beside the wounded man. The ground is very hard, you see, and there are no marks to guide us."
