In New York Times bestselling author Anthony Horowitz's ingenious fourth literary whodunit following The Word is Murder, The Sentence is Death, and A Line to Kill, Horowitz becomes the prime suspect in a murder investigation--and only one man can prove his innocence: his newly estranged partner in solving crime, Detective Hawthorne. "I'm sorry but the answer's no." Reluctant author, Anthony Horowitz, has had enough. He tells ex-detective Daniel Hawthorne that after three books he's splitting and their deal is over. The truth is that Anthony has other things on his mind. His new play, a thriller called Mindgame, is about to open at the Vaudeville Theater in London's West End. Not surprisingly, Hawthorne declines a ticket to the opening night. The play is panned by the critics. In particular, Sunday Times critic Margaret Throsby gives it a savage review, focusing particularly on the writing. The next day, Throsby is stabbed in the heart with an ornamental dagger which turns out to belong to Anthony, and has his fingerprints all over it. Anthony is arrested by an old enemy . . . Detective Inspector Cara Grunshaw. She still carries a grudge from her failure to solve the case described in the second Hawthorne adventure, The Sentence is Death, and blames Anthony. Now she's out for revenge. Thrown into prison and fearing for both his personal future and his writing career, Anthony is the prime suspect in Throsby's murder and when a second theatre critic is found to have died in mysterious circumstances, the net closes in. Ever more desperate, he realizes that only one man can help him. But will Hawthorne take the call?

Hurtling from present day New York to Victorian London, The Sherlockian weaves the history of Sherlock Holmes and Sir Arthur Conan Doyle into an inspired and entertaining double mystery that proves to be anything but "elementary." In December 1893, Sherlock Holmes-adoring Londoners eagerly opened their Strand magazines, anticipating the detective's next adventure, only to find the unthinkable: his creator, Arthur Conan Doyle, had killed their hero off. London spiraled into mourning-crowds sported black armbands in grief-and railed against Conan Doyle as his assassin. Then in 1901, just as abruptly as Conan Doyle had "murdered" Holmes in "The Final Problem," he resurrected him. Though the writer kept detailed diaries of his days and work, Conan Doyle never explained this sudden change of heart. After his death, one of his journals from the interim period was discovered to be missing, and in the decades since, has never been found.... Or has it? When literary researcher Harold White is inducted into the preeminent Sherlock Holmes enthusiast society, The Baker Street Irregulars, he never imagines he's about to be thrust onto the hunt for the holy grail of Holmes-ophiles: the missing diary. But when the world's leading Doylean scholar is found murdered in his hotel room, it is Harold-using wisdom and methods gleaned from countless detective stories-who takes up the search, both for the diary and for the killer.

Based on the Sherlock Holmes film: Ellery Queen matches wits with the Baker Street sleuth to unmask Jack the Ripper. Ellery Queen is struggling over his latest book when a friend brings him a mystery. It is a journal, written by a Victorian doctor, of reports on the remarkable adventures of his close friend, a brilliant detective named Sherlock Holmes. Queen's surprise turns to amazement as he turns its pages and discovers the lost story of Sherlock Holmes's greatest case: the pursuit of Jack the Ripper. From the brothels and back alleys of fog-choked Whitechapel to the manor of one of England's greatest families, Holmes and Dr. Watson chase history's most fearsome killer. But it will take the brilliance of Ellery Queen to solve the case once and for all. Based on the Sherlock Holmes film A Study in Terror , this collaboration between two of the world's greatest detectives is one of the most original mystery novels of all time.
