A doctor is accused of killing his divorced wife to marry her sister. Complicating matters for him is the fact that it is illegal to marry the sister of a divorced wife unless she (the divorced wife) is dead. This is a nice little suspenseful movie that kept me interested all the way through. Who else is involved? Will they find out in time? There's poisonous substances, a vengeful maid, and of course that pesky black orchid. I enjoyed watching this one and it was a rare treat. Let me know what you think.
