The sapphire meanwhile has also gone missing, or rather stolen. The maid (Lotus Long) seems involved in the theft, but in the murder too? It seems she knows who the murderer was and gets bumped off herself...
Karloff was always a good turn, and his Mr Wong character was very enjoyable. A complicated murder mystery with typical Golden Age touches (large house, motley crew of suspects). Edwards' wife Valerie (Dorothy Tree) overacts to a hilarious degree.
