"While on his beat, at a quarter past five o'clock this afternoon, Policeman John Flynn, hearing the report of a pistol from the direction of the Knickerbocker bank——"

"The Knickerbocker bank!" interrupted the young broker. "Mr. Dunlap, that interests you. Do your directors indulge in pistol practice at the board meetings?"

"What is that about the Knickerbocker bank?" asked the man to whom this speech was addressed. Having been engaged with his neighbor in an earnest discussion on financial questions, he had not been listening to the general conversation.

Murdock adjusted his eyeglasses, and quietly resumed:

"Policeman John Flynn, hearing the report of a pistol from the direction of the Knickerbocker bank, in Wall Street, started at the top of his speed toward that building. When he was within about twenty yards of the bank another shot rang out, and at the same instant a man darted down the steps and ran toward Broadway."

Richard Dunlap, president of the Knickerbocker bank, was listening attentively enough now. Behind the calm mask of the financier there was the evident anxiety of the bank president. For the stability of a bank, like the honor of a woman, is at the mercy of every passing rumor.

"He carried in his hand a small satchel, which he dropped as soon as he saw that he was pursued. After an exciting chase, Flynn overtook his man, whom he recognized as Michael Quinlan, alias Shorty Duff, a well-known sneak thief. On the way back to the bank the policeman questioned his prisoner about the pistol shots. Quinlan vehemently denied having fired them; but admitted that he had stolen the satchel. His story is that, as he was passing the bank, the outer door was ajar. Seeing the satchel in the vestibule, he entered, crouching low in order to avoid being seen through the inner door, the upper portion of which is of plate glass. Scarcely had he laid his hand upon the satchel when he was startled by the report of a pistol. For a moment he was dazed and undecided how to act. Then, as no one seemed to take any notice of his presence, he was quietly slipping off, when a second shot was fired. Panic-stricken, he took to his heels, only to be captured by Flynn.

"On reaching the bank Flynn found the outer door closed but not fastened. The heavy iron gate between it and the inner door was securely locked, however, so that it was impossible to enter. The Knickerbocker bank has a second entrance on Exchange Place. But this, too, is protected by a massive iron gate, which also was found locked. Flynn rapped for assistance, and the call having been answered by Policemen Kirkpatrick and O'Donnell, he left the former to watch the Exchange Place door, and the latter to guard the entrance on Wall Street, while he took his prisoner to the police station.

"Messengers were at once despatched to the house of Mr. Richard Dunlap, the president of the bank, and to that of Mr. George S. Rutherford, the cashier. The former was not at home, and the family being out of town, there was no one who knew where he was spending the evening."

Every eye turned toward Richard Dunlap as this paragraph was read. His features remained impassive, under the full control of the veteran financier; but to an observant eye like Sturgis's, the man's real anxiety was betrayed by the unconscious action of his right hand, which lay upon the table and played nervously with a fork.
