When Holmes and Watson are visited at Baker Street by a frightened figure in a stovepipe hat, their interest is immediately piqued. The bizarre man turns out to be the reclusive Prince Alexander, the only son of the King of the Netherlands. In despair, he relays his suspicions to them about a plot to steal the throne, a jilted marriage proposal, and an attempted poisoning.
The detective and his assistant agree to help solve the case and quickly enter a dazzling world of power, inheritance and ambition. Passing between the grandeur of The Langham and Claremont House, Holmes and Watson meet an array of enchanting and mysterious characters, each with their part to play in the struggle for the throne. With stakes this high, the game is bound to get dirty.
With chapter headings derived from the titles of Conan Doyle’s short stories, Kingston cleverly weaves together the explosions in London, the extinction of the male line of the Dutch royal house of Orange, and the death of Queen Victoria’s favourite and haemophiliac son, the Duke of Albany.
