"...none have come close to capturing the atmosphere of Conan Doyle’s original works as these books."
London, 1890. A freezing November.
As anarchists terrorize the city, a series of gruesome murders strikes deeper into its heart. Leading philanthropists are being slaughtered in alphabetical order, all members of a secret club, the Luminarians. And with each victim, a loved one mysteriously dies as well.
Sherlock Holmes and John Watson embark on a race to stop this self-styled 'Lucifer' whose motives are mysterious but whose methods are increasingly diabolical. Hampered by a new head of Scotland Yard and a vengeful journalist and distracted by a beautiful socialite with her own agenda, they attempt to close in on the killer.
As the murders continue, the letter 'H' climbs closer to the top of the list – and then Mycroft Holmes disappears. Must Sherlock Holmes himself cross to the dark side to take down this devil? Even John Watson, the man who knows him best, can only watch and wonder.
