In the first adventure of Robert Arthur's classic mystery series, it's 1964 in Rocky Beach, California. When Jupiter Jones, Pete Crenshaw, and Bob Andrews decide to get publicity for their new detective firm by locating a real haunted house for the renowned film director Reginald Clarke, Jupiter starts with the belief that there is no such thing as a ghost, a spook, a phantom, or a spirit. But Terror Castle - the old mansion supposedly troubled by the late Stephen Terrill, the silent horror film star called the Man with a Million Faces - may prove him wrong!
