He made me tell him exactly the circumstances of my seeing the men and my passing Peter and Jock previously; precisely in fact as I have told it in this account. He thought for a few moments in silence after I had finished and then asked me if I knew definitely of any other people who had sold anything to the sailors.
"I happen to know for certain of Dr. Rendall and his cousin Mr. Philip Rendall—or rather Mr. Philip Rendall's farmer, but from all I saw and all I heard I fancy the difficulty will be to find a house that did not sell something."
He nodded thoughtfully.
"That's exactly the difficulty," he said, and then he rose and held out his hand. "Goodnight, Mr. Merton, I'm much obliged to you and I'll promise you to make an excuse for looking you up very soon again and letting you know how I am getting on. By the way, you had better tell the doctor I was much interested in your account of how the explosion happened. That will account for my calling again."
"I must have detective instincts myself," I smiled. "I had already thought of the same lie."
In fact it came in very handy no later than Mr. Bolton's departure that night. The doctor wondered very much what the detective had to say to his patient that took him so long to tell, and his curiosity was satisfied as per arrangement.

WHERE THE CLUE LED
I saw nothing of Bolton next day, nor as a matter of fact did I expect to. Indeed, when he called for me on the morning after, it was a good deal sooner than I had counted on. The doctor was out, so no fable was necessary, and I took him into the smoking room and offered him an easy chair.
"Well, Mr. Bolton, any news?" I enquired.
