In her American film debut, British stage luminary Constance Collier dominates MGM's Shadow of Doubt as wealthy, reclusive Aunt Melissa, a character obviously based on "witch of Wall Street" Hettie Green. Emerging from a 20-year seclusion, Melissa announces her intention to disown her nephew Sim (Ricardo Cortez) if he marries temperamental actress Trenna (Virginia Bruce), who has been implicated in a double murder case. A ubiquitous presence throughout the picture is Sim's best friend, eternally inebriated columnist Reed Ryan (Regis Toomey), who's more than a little anxious to crack the case -- or so he claims. But the person responsible for the film's happy ending is none other than Melissa, who turns out to be a sweet old gal after all. Shadow of Doubt was one of a brief mid-1930s cycle of "female-detective" films, which included the Hildegarde Withers and Nurse Sarah Keane mysteries.
