A richly seductive world of passion, breathless intrigue, jeopardy, deception and revelations... Two years after the Reichenbach Falls, Sherlock Holmes has lost his hunger. Refusing to take on any new cases, he's listless, bankrupt and reduced to selling the stories of his past glories. But when his brother Mycroft is arrested for treason, Holmes is jolted back into action, and along with Watson and the mysterious Irene Adler, he must battle powerful, unknown forces in a race to save Mycroft's life. With demons of his own to fight, lost in a sea of madness, can Sherlock really save Mycroft from being hanged? Or will the deadly puzzles of the Best Kept Secret be the end of them all?
