The first in a stylish new series, in which the worlds of Sherlock and the uncanny collide.

Sherlock Holmes is dead. His body lies in a solitary grave on the Sussex Downs. But Dr. Watson survives, and is now given permission to release tales in Sherlock's 'black box', those cases that are, dear reader, unbelievable - for their subject matter is of the most outré and grotesque nature.

Beginning with 'The Adventure of the Lady's Finger', Holmes and Watson discover a dark, uncanny world beyond their imagining. It starts with a victim whose flesh reacts adversely to silver and sunlight, whose blood does not thicken when exposed to oxygen. And then a Transylvanian nobleman arrives at Baker Street demanding Holmes's assistance in the kidnapping of his beloved wife, Mina.

But Dracula is a client like no other and Sherlock and Watson must confront - despite the wild, unbelievable notion - the existence of vampires. Told in four long-hidden cases, Sherlock, Watson and their new vampire allies must soon work together to banish a powerful enemy growing in the shadows....
