A lost domain is regained, a lost sister is reclaimed--an old plot is retained. The catalyst is Aubrey, come to the south of France in the guise of a troubadour to warn his friend and former master-at-arms Olivier of Ormac that danger awaits his return from the Crusades. Chance draws his attention to a performing waif with a pretty face, ten-year-old Marjolaine, whom he gambles for and wins. With her as decoy, Aubrey entertains at the castle of Ormac, discovers that Olivier's place has been usurped by the baron of Mortaille, and first hears mention of the disappearance of Olivier's young sister Sybil some years before. The remainder is well-posted progress toward the obvious conclusions, with assists from loyal woodsmen. No distinctive characterization or telling incidents--just token dueling by lead soldiers in a cardboard castle.
