(1976) Thirteenth in Kenneth Bulmer's sword-and-planet series featuring Dray Prescot, an eighteenth-century adventurer transported to the planet Kregen. In this one, Prescot is disgraced and far from home, disguised as an officer of the enemy's army. The series is prone to episodic, Mary-Sue-ish narratives, so this volume is one of my favorites: its plot is more coherent than usual, and Prescot faces significant loss.
