There were yells of dismay from within before the last was said, and a rush of five crooks toward the open door.

Not a man among them ventured over its threshold however, or so much as drew a weapon in self-defense. The scene that met their gaze was enough to have daunted any gang of desperadoes.

For they found themselves confronted with half a score of leveled weapons, in the hands of as many determined men, and not one among them but knew that an aggressive move meant death.

It followed, therefore, that the arrest of the entire gang was an easy task. All were in irons in less than five minutes, and long before dark they occupied cells in the Shelby County Jail.

The money stolen from the express car was found in the cellar of the house, and later in the day was restored to the railway company.

Upon returning to the Shelby House with Nick and Patsy, all elated over their good work, Chick found a telegram awaiting him from Lieutenant Lang.

It told him that Dan Cady, the missing express-car man, had been found confined in Janet Payson’s flat in Philadelphia, in charge of another confederate, who had been arrested.

It then appeared that Cady had been on friendly terms with the woman and with Murdock, and that he had carelessly confided the fact that he was to carry a costly money package to Shelby on the night in question. This led to Murdock’s plot with his confederates, all having been awaiting the opportunity to commit the car robbery in the manner described, and Cady was lured to the flat in the early part of the day and overcome, Sol Mauler cleverly playing the part of his substitute.

This was rendered all the more feasible because of the fact that Murdock was one of the old railway hands, discharged for evil habits, and he was thoroughly familiar with all of the details essential to such a plot.

“It will teach Cady a lesson,” Nick remarked to Chick and Patsy that evening, as they sat smoking in their suite in the hotel. “He’ll select his companions more carefully in the future. As for Murdock and the gang—well, it now is up to them to pay the price.”
