The Professor gave a careful and detailed account of his adventures on the previous evening, to which Hanslet and Harold listened in silence. He finished by explaining that he had thought it useless to set the local police on the Black Sailor’s track, and Hanslet agreed.

“The fellow would have been miles away before you had got them to move,” he said. “Of course, I shall have to circulate his description again, in case anybody else saw him. But he can’t have gone about openly, with a reward on his head like that. Somebody would have been bound to have spotted him. It’s the most amazing story I ever heard. You don’t suppose he was pulling your leg, do you?”

“How did he know my name, and the names of the jurymen who served with me?” replied the Professor.

“Well, this case is full of most extraordinary contradictions. We’d better have a look at these bicycle tracks you speak of, it’s just possible we may be able to find out the direction in which he went off. Where did he mount his bicycle and ride away, Professor?”
