"Here's this murder of Fletcher, the retired banker and trustee of the University," he explained. "Not a clue-except a warning letter signed with this mysterious clutching fist. Last week it was the robbery of the Haxworth jewels and the killing of old Haxworth. Again that curious sign of the hand. Then there was the dastardly attempt on Sherburne, the steel magnate. Not a trace of the assailant except this same clutching fist. So it has gone, Jameson-the most alarming and most inexplicable series of murders that has ever happened in this country. And nothing but this uncanny hand to trace them by." The editor paused a moment, then exclaimed, "Why, this fellow seems to take a diabolical-I might almost say pathological-pleasure in crimes of violence, revenge, avarice and self-protection. Sometimes it seems as if he delights in the pure deviltry of the thing. It is weird."
