U.S. Marshal1958

[discussing the town constable's curious actions after a jailbreak]

Deputy Tom Ferguson:
Now there's a considerate husband. Two escaped prisoners, probably murderers, wandering around loose, but he doesn't want to worry his wife, so he closes up shop and goes home.

Marshal Frank Morgan:
What makes you so sure he's going home?

Deputy Tom Ferguson:
We can't very well tail him in broad daylight.

Marshal Frank Morgan:
We don't have to tail him - we just have to follow that dust cloud.

Deputy Tom Ferguson:
This dust is good for something after all.
