Moriarty. Anthony Horowitz. 2014.

Days after Sherlock 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 which has been swiftly filled by a fiendish new criminal mastermind who has risen to take his place.

Ably assisted by Inspector Athelney Jones of Scotland Yard, Chase must forge a path through the darkest corners of the capital to shine a light on this shadowy figure, a man determined to engulf London in a tide of murder and menace.
