At the height if his popularity, S.S. Vane Dine pens a locked-room mystery with a lethal dose of sex and sin where infamous actress, "The Canary," is murdered in her cage after a passionate night with her lover.

Margaret Odell, the famous Broadway beauty and ex-Follies girl known as "The Canary", is found murdered in her ransacked apartment, her jewelry stolen. It appears to be a robbery gone wrong, but the police can find no physical evidence to pinpoint a culprit. No one witnessed anyone entering or leaving, and the only unwatched entrance to the apartment building was bolted from the inside.

Who could have killed the Canary in her locked cage? Margaret was seeing a number of men, ranging from high society gentleman to ruthless gangsters, and more than one man visited her apartment on the night she died.
