 Elston Carr (Anthony Jochim) is searching for the heir to the Hocksley fortune, with Alan Neil (Warren Stevens) conducting the preliminary interviews. Miriam Hocksley (Mary Shipp) may be the heiress, but she can t prove it, so Neil coyly offers his services for a fee. Meantime, another woman, Doris Hocksley (Toni Gerry), also has reliable credentials. The proof is in a tin box in Carr s safe, but when opened it is empty, and Carr is lying on the floor dead.
