Knife in the Night — William M. James

Cuchillo Oro, Apache warrior, continues his bloody bid for revenge on the man who removed two of his fingers joint by joint, destroyed the peace of his tribal settlement, and murdered his squaw and son. Lieutenant Pinner is a marked man - a ruthless and sadistic Indian-hater who has finally met his match. Luck seems to be with him for the moment but sooner or later his time will come, and when it does he knows he can expect no mercy.
