Showing The Accidental Spy by J.R. Lindermuth

Dandy Dan McCracken is a rogue wandering around eastern Pennsylvania during the American Revolution. Wounded and on the run from the law, he's rescued and nursed to health by the lovely ward of Benedict Arnold's procurement officer. When the girl's husband returns from the front, McCracken falls in with British spies. He switches sides again as a result of love and becomes a hero, not through choice but circumstance.
