“So I suggested a scheme to Inspector Whyland, and here my chance thought of delivering a counter to myself came in useful. I was to go to Dorchester for the weekend⁠—I was thankful for the evidence I had already laid that the fatal period and place were the weekend and Praed Street⁠—and he was to remain here on the watch for the assassin who threatened me. It amused me to think that the solution of the whole mystery would lie under his very eyes, for the crossbow was on that bench, and the airgun stands in a rack in my bedroom. But, since I had invited him, I knew that he would attach no importance to these things, even if he noticed them. I left him in possession, and went to Dorchester. But from there I took a train to Wareham, and walked across the heath to Dr. Morlandson’s cottage, where I most artistically converted Mr. Ludgrove into the Black Sailor.
