It is December 1888. The body of Queen Victoria's physician is discovered in a railway carriage on Paddington Station. Sherlock summons his brother Mycroft to the scene. Sherlock is convinced the crime bears resemblance to the Ripper murders but when a letter arrives at Scotland Yard, ostensibly from the Ripper, claiming he is the author of the crime, Lestrade doubts Sherlock's wisdom. When the body of Sir James Fawcett, a leading expert on tropical diseases, is found at his home in Chelsea the day after, Sherlock realises that a challenging criminal mind is at work. This Sherlock Holmes vel, which follows the author's own chrology of the cases of Holmes, introduces readers to a number of real life Victorian celebrities, including Oscar Wilde. By the author of 'Sherlock Holmes, Consulting Detective.'
