It is the autumn of 1880, and Dr. John Watson has just returned from Afghanistan. Badly injured and desperate to forget a nightmarish expedition that left him doubting his sanity, Watson is close to destitution when he meets the extraordinary Sherlock Holmes, who is investigating a series of deaths in the Shadwell district of London. Several bodies have been found, the victims appearing to have starved to death over the course of several weeks, and yet they were reported alive and well mere days before.

It’s the autumn of 1890, and a spate of bombings has hit London. The newspapers are full of fevered speculation about anarchists, antimonarchists and Fenians. But one man suspects an even more sinister hand behind the violence. Sherlock Holmes believes Professor Moriarty is orchestrating a nationwide campaign of terror, but to what end? At the same time, a bizarrely garbed figure has been spotted on the rooftops and in the grimy back alleys of the capital.  

The iconic duo find themselves swiftly drawn into a series of puzzling and sinister events: an otherworldly stone whose touch inflicts fatal bleeding; a hellish potion to unlock a person’s devilish psyche; a fiendishly clever, almost undetectable method of revenge and many more—including a brand-new Cthulhu Casebooks story.

Beginning with A Study in Scarlet and concluding with The Hound of the Baskervilles, this epic project took over 8 years to complete - and this landmark collection contains the extraordinary result. Here is the world's first ever fully dramatised Sherlock Holmes canon: 56 short stories and 4 novels, all made by the same team of directors, producers, dramatists and leading actors, and packed with the high production qualities of a film or TV drama that set it apart.
