The Kennel Murder Case (1933)

Everyone assumes dog-show competitor Archer Coe (Robert Barrat) committed suicide -- except for intrepid detective Philo Vance (William Powell). As Vance investigates, he turns up evidence of foul play that points in every direction; Coe wasn't just disliked -- he was despised. The long list of suspects includes Coe's niece Hilda (Mary Astor) ; his rival, Sir Thomas MacDonald (Paul Cavanagh) ; and his brother. Can Vance sort through the competing motives to find the true killer?
