Summer. A dark, brooding season of oppressive heat and thunderstorms, and Flotsam yearns for fresh air and a sea breeze. But business is brisk in Baker Street and becomes even brisker when a lady who purports to be a spiritualist brings Sherlock Holmes a mysterious message from the dead.

It is spring in Baker Street, and London is preparing itself for the wedding of the year. It will be an international spectacle in which the young and popular Count Rudolph Absberg, a political exile from his native land, will take the hand of the beautiful and accomplished Princess Sophia Kubinova.

When a priceless ruby known as the Malabar Rose vanishes while being guarded by Sherlock Holmes and his assistant, Dr. Watson, the formidable Mrs. Hudson sets out to give a lesson in criminal deduction for her most famous and logical of tenants, the master sleuth himself.

An evil stalks London, blown in from the tropics. Stories of cursed giant rats and malign spirits haunt the garrets of the East London neighbourhood of Limehouse. A group of merchants are dying one by one.
