Anthony Horowitz's Second Sherlock Holmes Novel, Moriarty, to be Published in October 2014

Anthony Horowitz is planning a second novel set in the world of Sherlock Holmes titled Moriarty. Orion is publishing the book in the UK, which has an October 24th, 2014 release date.

Set after the events of "The Final Problem", in which Sherlock Holmes and James Moriarty plunge to the presumed deaths, Moriarty will open with, "Does anyone believe what happened at the Reichenbach Falls?"

"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," says the synopsis on Amazon.co.uk. "Ably assisted by inspector Athelney Jones of Scotland Yard, a devoted student of Holmes' 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."

Horowitz himself revealed on Twitter that "Sherlock Holmes does not appear (until the very end)", that "a vicious murder is investigated by Inspector Athelney Jones (from The Sign of Four)" and that "nearly all the policemen Holmes ever worked with, including Lestrade, appear in my new book".

Horowitz's first Sherlock Holmes novel is The House of Silk, published by Mulholland Books in the US in November 2011.
