Mr. Stuyvesant bowed, every wrinkle in his face manifesting itself with startling distinctness as he slowly moved his eyes and fixed them on the inscrutable countenance of the detective. “You agree then with these gentlemen,” continued the latter, who had a way of seeming more interested in everything and everybody present than the person he was addressing, “that it would be difficult if not impossible for any one unconnected with the bank, to approach the vaults during business hours and abstract anything from them without detection?” “And do these gentleman both assert that?” queried Mr. Stuyvesant, with a sharp look from uncle to nephew. “I believe they do,” replied the detective, as both the gentlemen bowed, Bertram with an uncontrollable quiver of his lip, and Mr. Sylvester with a deepening of the lines about his mouth, which may or may not have been noticed by this man who appeared to observe nothing. “I should be loth to conclude that the robbery was committed by any one but a stranger,” remarked Mr. Stuyvesant; “but if these gentlemen concur in the statement you have just made, I am bound to acknowledge that I do not myself see how the theft could have been perpetrated by an outsider. Had the box itself been missing, it would be different. I remember my old friend Mr. A—, the president of the police department, telling me of a case where a box containing securities to the amount of two hundred thousand dollars, was abstracted in full daylight from the vaults of one of our largest banks; an act requiring such daring, the directors for a long time refused to believe it possible, until a detective one day showed them another box of theirs which he had succeeded in abstracting in the same way.[1] But the vaults in that instance were in a less conspicuous portion of the bank than ours, besides to approach an open vault, snatch a box from it and escape, is a much simpler matter than to remain long enough to open a box and choose from its contents such papers as appeared most marketable. If a regular thief could do such a thing, it does not seem probable that he would. Nevertheless the most acute judgment is often at fault in these matters, and I do not pretend to have formed an opinion.” [Footnote 1: A fact.] The detective who had listened to these words with marked attention, bowed his concurrence and asked if the bonds mentioned by Mr. Stuyvesant were all that had been found missing from the bank. If any of the other boxes had been opened, or if the contents of the safe itself had ever been tampered with.
