In Dust and Shadow Sherlock Holmes hunts down Jack the Ripper with impeccably accurate historical detail, rooting the Whitechapel investigation in the fledgling days of tabloid journalism and clinical psychology. This astonishing debut explores the terrifying prospect of hunting down one of the world's first serial killers without the advantage of modern forensics or profiling. Sherlock's desire to stop the killer who is terrifying the East End of London is unwavering from the start, and in an effort to do so he hires an "unfortuate" known as Mary Ann Monk, the friend of a fellow streetwalker who was one of the Ripper's earliest victims.

As Holmes and Watson seek out the terrifying interlopers, the scene is set for the final battle that will bring them face to face with the Sussex Sea-Devils, and perhaps with Cthulhu himself...
