"About the middle of the train. See that green cattle car? The old man was riding in the box right ahead of it."

"Stop the train."

The brakeman stuck his flag out a side window and waved frantically. After several minutes, a head bobbed up from the locomotive cab.

"That's the conductor. He sees us."

"Wave your flag."

The locomotive's chugging slowed down. Bell felt the brake shoes grind. The cars banged into one another as they filled the slack caused by the train slowed to a stop. He watched the roofs of the boxcars.

"Soon as the train stops, I want you to run ahead and check each car. Do not engage. Just give a shout if you see anyone, then get out of the way. He'll kill you soon as look at you."

"Can't."

"Why not?"

"We have to send a flagman back when we stop. I'm it. In case a train's following us, I have to wave it down. Wires are screwy today."

"Not before you check each car," said Bell, drawing the Browning from his coat.

The brakeman climbed down from the cupola. He jumped from the rear platform to the tracks and jogged alongside the train, pausing to look into each car. The engineer blew his whistle, demanding an explanation. Bell watched the rooftops and moved to either side of the cupola, to see alongside the train.

THE WRECKER LAY ON his back in a bench locker less than ten feet from the cupola ladder, gripping a knife in one hand and a pistol in the other. All night, he had worried that by setting loose the runaway gondola he had put himself in danger by trapping himself so far up the line. Fearing that railway police, goaded by Van Dorn detectives, would mob the train before it reached Weed or Dunsmuir and search it thoroughly, he had taken decisive action. During the last water stop, he had run back to the caboose and slipped inside while the crew were busy tending the locomotive and checking the journal boxes under the railcars.

He had chosen a locker that held lanterns, reasoning that no one would open it in the daytime. If someone did, he would kill him with whichever weapon suited the moment, then spring out and kill anyone else he came across.

He smiled grimly in the cramped, dark space. He had guessed right. And who had boarded the train but none other than Van Dorn's chief investigator himself, the famous Isaac Bell? At worst, the Wrecker would make a complete fool out of Bell. At best, he'd shoot him between the eyes.

THE BRAKEMAN CHECKED EVERY car, and when he reached the locomotive Bell saw him confer with the conductor, the engineer, and the fireman, who had gathered on the ground. Then the conductor and the brakeman hurried back, checking each of the fifty boxcars, cattle cars, and gondolas again. When they got to the caboose, the conductor, an older man with sharp brown eyes and a put-out expression on his lined face, said, "No saboteurs. No hobos. Nobody. The train is empty. We've wasted enough time here."
