Juan Cesare, a descendant of the Borgia's of Vienna, thinks he may have a murder streak in him acquired from his long-dead relatives, is is love with Florence Ballau, but her father lodges a strong protest. Papa Ballau is later found dead with a Florentine dagger of the Borgia type stuck firmly in him. Juan is all wrought up and tortured by thoughts he may have been the killer. But there is also a disfigured housekeeper on the premises who may or may not have had a motive.—Les Adams <[email protected]>
