Ticket to a Crime1934

At a prestigious soiree at the swank Lido Country Club, wealthy Mr. Davidson is gunned down in a dispute over a string of valuable pearls. Private investigator Clay Holt and his plucky secretary, Peggy Cummings, enter the case and turn up plenty of suspects. Gumming up the works is inept police detective John McGinnis who wants to join the investigation. Keeping meddlesome McGinnis at arm's length, Holt zeroes in on the culprit by setting a clever trap in Mr. Davidson's own mansion.
