Ranson's Folly is the title story in this collection of novellas which also includes The Bar Sinister; A Derelict; La Lettre D'Amour; and, In The Fog. Ranson's Folly tells the story of the audacious, dare-devil exploits of a junior officer in the U.S. Army. His position and influence secure a lieutenancy in a Western post. The monotony of the life there and its regularity finally drive him into the folly of donning the disguise of a band of notorious highwaymen, and holding up the public coach.
