Compromising photographs and a case of blackmail threaten the very heart of the British establishment, but for Sherlock and John the game is on in more ways than one as they find themselves battling international terrorism, rogue CIA agents, and a secret conspiracy involving the British government. This case will cast a darker shadow over their lives than they could ever imagine, as the great detective begins a long duel of wits with an antagonist as cold and ruthless and brilliant as himself: to Sherlock Holmes, Irene Adler will always be THE woman.
Something terrible has happened to Henry Knight; Sherlock and John investigate the truth about the monstrous creature which apparently killed their client's father. A hound from hell? What seems like fantasy in Baker Street is a very different prospect in the ultra-secret army base that looms over Dartmoor.
James Moriarty possesses the greatest criminal mind that the world has ever seen. Sherlock and John knew he wouldn't stay hidden for long, but even they never guessed the sheer scale and audacity of the crime that would propel Moriarty back into the headlines. Sherlock must fight for his reputation, his sanity and his life. But is he all he claims to be?
