"The cashier fortunately was at home, and he hurried down town at once with his set of the bank keys. Two detectives from the Central Office accompanied him, and the three men carefully searched the premises. They found nothing out of the way there, except that three gas jets were lighted and turned on full blaze. At first the detectives were inclined to think that bank robbers had gained an entrance to the building; and that one of them, having caught sight of Shorty Duff as he reached in to steal the satchel from the vestibule, had fired upon him. This would explain the pistol shots heard by Flynn. A careful examination of the bank, however, failed to reveal any trace of a bullet. "The valise, when opened, proved to contain only a change of linen for a man and a few toilet articles of but slight intrinsic value. The satchel itself is an ordinary cheap leather handbag, stamped in imitation of alligator skin. "The police are now looking for its owner in the hope that he will be able to throw some light on the mystery of the pistol shots." When Doctor Murdock had finished reading, everybody, except Dunlap and Sturgis, looked disappointed. The former settled back in his chair, the muscles of his face relaxed, and the anxious bank president once more became the genial and polished man of the world. The reporter sat gazing thoughtfully at his wineglass. "Well, Mr. Sturgis," said Murdock, "what do you think of my little problem?" "I have already been assigned to work up this case for the _Tempest_," answered the reporter quietly. "Indeed? Perhaps you are the author of this very article? No? Then are you willing to make the solution of this little mystery the subject of our wager and the test of your theories?" "Hold on, Doctor," exclaimed Sprague; "you are doing Sturgis an injustice. Why pick out, as a test of his ability, a problem which, to all intents and purposes, has already been solved by the police? Give him some truly knotty question and he will be in his element; and then, at least, some interest will attach to your wager." "Ah! you think the problem has already been solved?" "To be sure. The article you have read us started out as if it were going to prove interesting; but, instead of that, it ends in an anti-climax. What is the crime here? The confessed theft, by a petty sneak thief, of a satchel worth, with its contents, perhaps eight or ten dollars. And where is the mystery? The ownership of a few pieces of unmarked linen of so little value that the owner does not care to take the trouble to claim them."
