The game is once again afoot in this thrilling mystery from the bestselling author of The House of Silk, sanctioned by the Conan Doyle estate, which explores what really happened when Sherlock Holmes and his arch nemesis Professor Moriarty tumbled to their doom at the Reichenbach Falls.
Internationally bestselling author Anthony Horowitz’s nail-biting new novel plunges us back into the dark and complex world of detective Sherlock Holmes and Moriarty—dubbed the Napoleon of crime” by Holmes—in the aftermath of their fateful struggle at the Reichenbach Falls.
Days after the encounter at the Swiss waterfall, Pinkerton detective agent Frederick Chase arrives in Europe from New York. Moriarty’s death has left an immediate, poisonous vacuum in the criminal underworld, and there is no shortage of candidates to take his place—including one particularly fiendish criminal mastermind.
Chase and Scotland Yard Inspector Athelney Jones, a devoted student of Holmes’s methods of investigation and deduction originally introduced by Conan Doyle in “The Sign of Four”, must forge a path through the darkest corners of England’s capital—from the elegant squares of Mayfair to the shadowy wharfs and alleyways of the London Docks—in pursuit of this sinister figure, a man much feared but seldom seen, who is determined to stake his claim as Moriarty’s successor.
A riveting, deeply atmospheric tale of murder and menace from one of the only writers to earn the seal of approval from Conan Doyle’s estate, Moriarty breathes life into Holmes’s dark and fascinating world.

My rating: 4 stars out of a scale of 5

My review: This book will be counting towards my goal for the Pop Sugar Reading Challenge 2015 checklist under the “a book with a one-word title” check box since the book has one word for its title. I picked this book up because of the description on the inside cover. I love the Sherlock Holmes movies that have been produced in the last couple of years and every time I watch the second movie I am left with the same burning question, what happened to Sherlock Holmes and Professor Moriarty after they plummeted down into Reichenbach Falls!!??
And so begins our tale. We begin in the place where the last story ended, Reichenbach Falls. Our narrator, Frederick Chase, and his soon-to-be friend, Athelney Jones, first meet here and Chase enlists Jones’ help in bringing down a notorious American crime lord who has recently arrived in London to take over the crime world. Trying to save the streets from the viciousness of Clarence Devereuxx, Chase and Jones team up to put a stop to his madness.

I cant say much more about the book without giving away the ending but I just have to say I was completely floored by the twist of events at the end of the book, I never saw it coming! The ending really made the book for me, I liked it ok right up until the second to last chapter, and then I loved it!
