Sherlock Holmes is dead. Days after Holmes and his arch-enemy Moriarty fall to their doom at the Reichenbach Falls, Pinkerton agent Frederick Chase arrives in Europe from New York. The death of Moriarty has created a poisonous vacuum that has been swiftly filled by a fiendish new criminal mastermind who has risen to take Moriarty’s place. Ably assisted by Inspector Athelney Jones of Scotland Yard, a devoted student of Holmes’s methods of investigation and deduction, Frederick Chase must forge a path through the darkest corners of the capital to shine light on this shadowy figure, a man much feared but seldom seen, a man determined to engulf London in a tide of murder and menace. Author of the global bestseller The House of Silk, Anthony Horowitz once more breathes life into the world created by Sir Arthur Conan Doyle. With pitch-perfect characterization and breathtaking pace, Horowitz weaves a relentlessly thrilling tale that teases and delights by the turn of each page. The game is afoot . . .
