“Very good,” Nick said approvingly. “Pay no attention to any persons who may be on the platform, or step from the train during the stop. An inquisitive stare might cause misgivings.”

“I’m wise, Mr. Carter,” Denny assured him. “I’ll do precisely as if I knew nothing about this deviltry. I’m over seven, you know, and——”

He was interrupted by the sudden, rapid ticking of the telegraph instrument. It proved to be a dispatch for the engineer of the coming train, and Denny scarce had transcribed it when the whistle of the locomotive sounded in the near distance.

Half a minute later the glare of its headlight appeared amid the scattered lights of the town, from which it emerged at high speed and immediately began slowing down to make the junction.

“Come on!” Denny cried, leading the way. “She stops only five minutes.”

Nick followed him from the chamber and down the long flight of stairs from the tower. He could feel the structure trembling under the vibrations caused by the heavy train, which then was approaching the long platform and coming to a stop, amid the clanging of the locomotive bell, the furious hissing of steam, and the grinding of the brakes.

Only a solitary man was pacing the platform, carrying a traveler’s grip and a light overcoat. Nick saw at a glance that he was a commercial drummer and not worthy of suspicion.

Several men stepped from the train, obviously to break the monotony of a night journey, but neither the looks or actions of any appeared suspicious. Nick quickly noted the make-up of the train, a baggage car, the express car, a smoker, an ordinary passenger car, and two Pullman sleepers in the rear. He knew that Chick was on the train, but he did not know just where, nor particularly care at that moment.

Denny ran to the locomotive and gave the engineer the dispatch, then hurriedly rejoined Nick and led the way to the express car.

The sliding side door was thrown open from within while they approached, and Denny quickly greeted the man who appeared in the brightly lighted car.
