Comments: A millionaire, Frederick Loren, is willing to pay any individual $10,000 to spend the night in his "haunted" house. Five individuals of various backgrounds are invited by Frederick to take the challenge. His wife Annabelle wants a party in the house so the caretakers will lock them in at midnight! One guest knows about those who were murdered in the house and warns that more murders will occur.
This classic is a good, old-fashioned whodunit without gore or cheap scares. It makes an excellent Halloween film. Recommended.
