to crime until he does something very bad and ends on a gallows. The case
has, in some respects, been not entirely devoid of interest."

"I cannot now entirely see all the steps of your reasoning," I remarked.

"Well, of course it was obvious from the first that this Mr. Hosmer Angel
must have some strong object for his curious conduct, and it was equally
clear that the only man who really profited by the incident, as far as we
could see, was the stepfather. Then the fact that the two men were never

facts, together with many minor ones, all pointed in the same direction."

"And how did you verify them?"

"Having once spotted my man, it was easy to get corroboration. I knew the
