of the substitution when they contact the police and their insurance companies. Scotland Yard has traced the work done on the jewels to a company called Golconda, and from there to Paul Varesco. The police raid the club but are unable to find any jewels or drugs secreted in the club or on anyone there, particularly Varesco.

When the raid occurred and the lights went out temporarily, Poirot was waiting by Cerberus and heard her put the packet in the dog's mouth – and Poirot took the
