This Brit murder mystery-chiller takes place at a creepy, haunted estate called Raven Hall, where an assortment of odd people have gathered. Included are a stuffy policeman, a fearful servant girl, a slick crime reporter, a stodgy old aunt, and of course, a terrifying masked man who peers through the windows. Watch for the scene where the front door slowly opens by itself. Brrr At the heart of it all are stolen jewels, which are thought to be hidden somewhere in the estate.
