The Falcon's Brother

Dapper detective Gay Lawrence (George Sanders) and his partner, Lefty (Don Barclay), arrive to greet Gay's brother Tom (Tom Conway) who has just arrived on a cruise ship, but the sleuthing duo are told that Tom committed suicide in his cabin. Gay tells Lefty that the body isn't Tom's and the victim has been murdered. Soon Lefty is falsely accused of murder, and Gay is knocked out when he's hit by a car. It is left to a reappeared Tom to exonerate Lefty and foil an international conspiracy.
