A dying woman scrawls a number in blood as a clue

The sleuth investigates the death of a woman whose dying act was to scrawl a number in her blood as a clue. It identifies a storage compartment - about to be auctioned - which had been rented by her late brother. He was the victim of a suspicious accident some months previously, and a link is made between him and the theft of a valuable diamond from his former employer. Nathan Fillon stars
