Murder in the Blue Room

Mystery writer Steve Randall (Donald Cook) accepts an invitation by Nan Kirkland (Anne Gwynne) to the reopening of her mother's house. Nan tells Steve and her friends that the house is haunted by the ghost of her father, who committed suicide in the "blue room." Skeptical, Nan's former boyfriend insists on spending the night in the blue room, only to disappear. After a fruitless police investigation, Steve decides to spend the night in the blue room -- and promptly vanishes as well.
