After the murder of a man in Calcutta, Inspector Marney (Lewis Stone) is bought in to investigate this baffling case. "Help" comes from an unexpected direction as Madame La Grange (May Whitty) to performance a seance with a group of people linked to the victim, one of whom is probably the murderer.
However, during the seance another man is murdered! Marney investigates the case, this time he is sure the murderer is in the room, and a number of secrets are revealed...
This is a highly enjoyable crime film with tasty additions of Eastern mystery and mysticism. Not as witty or intelligent as an Agatha Christie type of story but not bad at all. The crime itself and how it is solved is a lot more down to earth though. Some great twists and a good character mix make this a pretty good film.
