William Le Queux

An anthology series produced by Thames Television, comprised of short mystery, suspense or crime adaptations featuring, as the title suggests, detectives who were literary contemporaries of Arthur Conan Doyle's Sherlock Holmes.

The young boy Normand grows up to become the mastermind of a complex criminal network in London. He runs not only a gang of thieves but also a blackmail operation, a film company, and a newspaper, all in aid of shady dealings. Normand's cunning has helped him evade the law so far, but after his theft of the Littleborough jewels, he finds he may have pushed his luck too far.
