Scotland Yard has made its mistakes but somehow it seems impossible that this could have been one of them. When Belle Russell calls on private eye (or would the British call it ""exclusive orb""?) Mike Logan to find her twin sister who has disappeared, the bodies start falling. The Yard is concerned with this debris, but it never occurs to the owners of the world's biggest record cabinet to check and see whether or not Belle Russell really had a twin or vice versa. But Logan -- 'e's a smart one.
