In "Aria From Murder," opera singer Ezio Pinza stars as a baritone who commits murder only to end up being blackmailed by the fan who witnessed the crime.
It all began with a weakness for a woman, Leola Dantes. She wasn't his wife, but she was the woman he loved. The general manager of the opera company, Felix Levine, found out about NIcolo's relationship with her and confronted him. Leola wasn't the only trouble Nicolo had gotten himself into, he was also overdrawn on all of his credit accounts. Felix informs him that he is breaking their contract.
Niccolo then kills Felix on the stage of the empty opera house, but then realizes that there was still one person in the audience...
