The Bromley Case (1920)

John Bromley Jr., an inveterate gambler, becomes so overwhelmed with debt that he is forced to steal from his wealthy father's safe. The night of the robbery he breaks into his father's house with Harvey Knowles, the gambler to whom he is indebted. The next morning, Bromley Sr. is found murdered and Tex, a noted criminologist, is brought in to solve the crime. At first, John Jr. is accused, then the guilt shifts to Bromley's other son Bruce, who had just been fired by his father. Also under suspicion is Frances Belmore, a woman of ill repute who had attempted to ensnare Bromley. Finally, all three are cleared when Tex discovers that the butler did it while attempting to abscond with the contents of the safe.
