THE GAME'S AFOOT...November 1890. London is gripped by a merciless winter. Sherlock Holmes and Dr Watson are enjoying tea by the fire when an agitated gentleman arrives unannounced at 221b Baker Street. He begs Holmes for help, telling the unnerving story of a scar-faced man with piercing eyes who has stalked him in recent weeks. Intrigued, Holmes and Watson find themselves drawn into a series of puzzling and sinister events, stretching from the gas-lit streets of London to the teeming criminal underworld of Boston. As they delve deeper into the case, they stumble across a whispered phrase the House of Silk: a mysterious entity and foe more deadly than any Holmes has encountered, and a conspiracy that threatens to tear apart the very fabric of society...

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.

Retired publisher Susan Ryeland is living the good life. She is running a small hotel on a Greek island with her long-term boyfriend Andreas. It should be everything she's always wanted - but is it? She's exhausted with the responsibilities of making everything work on an island where nothing ever does, and truth be told she's beginning to miss her old life in London.
And then a couple - the Trehearnes - come to stay, and the story they tell about an unfortunate murder that took place on the same day and in the same hotel in which their daughter was married, is such a strange and mysterious one that Susan finds herself increasingly fascinated by it. And when the Trehearnes tell her that their daughter is now missing, Susan knows that she must return to London and find out what really happened...

Murder links past and present once again in this mind-boggling metafictional mystery from Anthony Horowitz—another tribute to the golden age of Agatha Christie featuring detective Atticus Pund and editor Susan Ryland, stars of the New York Times bestsellers Magpie Murders and Moonflower Murders.

Editor Susan Ryeland has left her Greek island, her hotel, and her Greek boyfriend Andreas in search of a new life back in England.
Freelancing for Causton Books, she’s working on the manuscript of a novel, Pund’s Last Case, by a young author named Eliot Crace, a continuation of the popular Alan Conway series. Susan is surprised to learn that Eliot is the grandson of legendary children’s author Marian Crace, who died some fifteen years ago—murdered, Elliot insists, by poison.

As Susan begins to read the manuscript’s opening chapters, the skeptical editor is relieved to find that Pund’s Last Case is actually very good. Set in the South of France, it revolves around the mysterious death of Lady Margaret Chalfont, who, though mortally ill, is poisoned—perhaps by a member of her own family. But who did it? And why?

The deeper Susan reads, the more it becomes clear that the clues leading to the truth of Marian Crace’s death are hidden within this Atticus Pund mystery.

While Eliot’s accusation becomes more plausible, his behavior grows increasingly erratic... Then he is suddenly killed in a hit-and-run accident, and Susan finds herself under police scrutiny as a suspect in his killing.

Three mysterious deaths. Multiple motives and possible murderers. If Susan doesn’t solve the mystery of Pund’s Last Case, she may well be the next victim.

They told him his uncle died in an accident. He wasn't wearing his seatbelt, they said. But when fourteen-year-old Alex finds his uncle's windshield riddled with bullet holes, he knows it was no accident. What he doesn't know yet is that his uncle was killed while on a top-secret mission. But he is about to, and once he does, there is no turning back. Finding himself in the middle of terrorists, Alex must outsmart the people who want him dead. The government has given him the technology, but only he can provide the courage. Should he fail, every child in England will be murdered in cold blood.

They’re making a major feature film of the first Hawthorne/Horowitz mystery novel. Except—they’re behind schedule, they’ve run out of money and . . . oh! The star has just been murdered.
