Errol Flynn makes his Hollywood screen debut as a corpse in this funny, fast-paced whodunit, the third of six Perry Mason vehicles produced by Warner Bros. from 1934 to 1937. Flynn's murder victim is one Gregory Moxley, the estranged and long-thought dead husband of Perry's client, Rhoda Montaine (Margaret Lindsey), who, in the meantime, has married a millionaire (Donald Woods) and is ripe for blackmail. Perry agrees to meet with Moxley, but finds him very much dead and this time for good. Rhoda naturally becomes the prime suspect, but, with the able assistance of his wisecracking secretary Della Street (Claire Dodd), Perry is able to reveal the identity of the real culprit, not in the courtroom this time, but at an elegant cocktail party.
