It was a dark and stormy night...

During a rainstorm at a remote manor house, Richard Crayell plays host to several guests. At nine o'clock sharp, he excuses himself from the card table to take his medicine, promising to return soon. When he doesn't, Claire goes in search of him, and finds his door locked from the inside. The men break down the door and find a body. The guests include Inspector Carr and Dr. Crabtree, a criminologist. Crabtree sets to work investigating. Will he find the culprit?
