"They're pulling us up at Maple.

If it's not a washout, somebody will get fired." He went off, grumbling, but when the train stopped came back with a trooper of the North-West Mounted Police.
"Where's the guy you told me to watch out for ?" he asked.
Lister said he did not know and offered to go with them and help find the man.

It looked as if he were going to see the end of the play.
When they opened a vestibule door a man came out of the car in front and stopped, as if he were dazzled by the beam from the conductor's lifted lamp.
"That's the fellow," Lister shouted.
He thought the other saw the trooper's uniform, because he stepped back quickly.

The door, however, was shut.

When he let go the handle the spring-bolt had engaged.
"Nothing doing that way!" said the trooper.
