"He with difficulty climbed upon the box beside Reilly and ordered him to drive uptown. Presently the cabman became drowsy again. The next thing he remembers is coming to himself after the overturning of the cab by the cable car. That the man was drugged there can be no doubt. It is probable that while he sat apparently drunk in the barroom, Chatham took the cab to the Knickerbocker bank, expecting to smuggle Arbogast into it without Reilly's knowledge;--a deep move, since it would effectually cover up the trail, if they wanted to make away with the bookkeeper, as they evidently did. Seymour may have met him at the bank by appointment; but I am more inclined to believe that he was there unknown to Chatham, and possibly for the purpose of spying upon the latter, to see that his instructions were carried out. He lent his accomplice a hand in the nick of time; and then, like a prudent general, he retired to a safe position, thence to direct further operations. What I cannot yet understand is, why Chatham should have taken the enormous risk he did in conveying Arbogast's body from the bank, since Seymour's intention was plainly to make away with the bookkeeper in any event. I can explain this only on the supposition that Seymour thought he could conceal the body in some way and prevent it from falling into the hands of the police. On the part of any ordinary criminal this would have been rank folly; but the resources of such a man as Seymour are such that I do not feel disposed to criticize his generalship in this particular without first understanding his ultimate object. From what I have seen of his work thus far, I have derived a profound admiration for the man's genius and cunning deviltry. Fortunately, fate was against him this time. Its instrument was the cable car which overturned the cab, thus delivering Arbogast's body into the hands of the police and furnishing the key without which, it is quite likely, Seymour might have remained forever undiscovered." "You think, then, that you will succeed in unearthing this villain?" asked Dunlap eagerly. "While there's life, there's hope," said Sturgis, with grim determination; "but I must confess that the outlook at present is not exactly brilliant. However, let me finish my report. During the excitement that followed the overturning of the cab, Chatham managed to escape, as you know, and he has thus far succeeded in avoiding arrest, although the police have kept a sharp lookout for him. Every steamship that sails, every train that leaves New York, is watched, but thus far without result. For my part, I am convinced that Chatham has not yet attempted to leave the city." "Isn't it probable, on the contrary, that he fled from New York immediately after running away from the overturned cab?" asked Dunlap.
