(Verdi: Rigoletto). Bass. A professional assassin hired by Rigoletto to kill the Duke of Mantua, who has seduced Rigoletto's daughter Gilda. Sparafucile's sister Maddalena agrees to help him by posing as a whore in a tavern and attracting the Duke to her. Maddalena urges her brother to let the Duke go free, and he agrees to do so on condition that whoever enters the inn next will be killed in his place.
