"Yes. What have you found out about that missing switch-engine?" This had come to be the stereotyped query, vocalizing itself every time the trainmaster showed his face in the superintendent's room.

"Nothing, yet. I'm hunting for proof."

"Against the men you suspect? Who are they, and what did they do with the engine?"

McCloskey became dumb.

"I don't dare to say part of it till I can say it all, Mr. Lidgerwood. You hit too quick and too hard. But tell me one thing: have you had to report the loss of that engine to anybody higher up?"

"I shall have to report it to General Manager Frisbie, of course, if we don't find it."

"But haven't you already reported it?"

"No; that is, I guess not. Wait a minute."

A touch of the bell-push brought Hallock to the door of the inner office. The green shade was pulled low over his eyes, and he held the pen he had been using as if it were a dagger.

"Hallock, have you reported the disappearance of that switching-engine to Mr. Frisbie?" asked the superintendent.
