The Greene Murder Case

Powell stars as sophisticated detective Philo Vance, who is brought in to investigate the killing of multi-millionaire Tobias Greene. Vance brings together a handful of likely suspects, but it soon becomes apparent he hasn't found the guilty party when all nine of the possible candidates also wind up dead. Vance starts taking a closer look at Greene's mourning family -- as well as the circumstances under which he earned his fortune. (allmovie.com)
