This is one of those British quota quickies in which the only name I recognize is cinematographer Ernest Palmer. It starts out with John Stuart getting engaged to Judy Kelly, some talk about the household ghost, the Black Abbot, then Miss Kelly's father is kidnapped.
It's a lesser variety of the British Locked Room mystery, with silly-ass humor and servants canoodling each other. Palmer's camera-work is wonderful -- lots of moving shots --but the performances are all over the shop, indicating that director George Cooper either couldn't afford to hire decent actors for the smaller roles, or couldn't direct actors for beans. At 54 minutes it's bearable, but I won't be revisiting.
