Anthony Horowitz OBE (born 5 April 1955) is an English novelist and television writer.
He created the mediveal adventure series Crossbow in the 1980s, popular television series Foyle's War and the rather less popular Crime Traveller, which functioned as a Genre-Killer for UK Science Fiction television in the 1990s and early 2000s. Other series he has worked on include Robin of Sherwood, Poirot, Murder Most Horrid and Midsomer Murders.
He has also written several novels in existing franchises. He wrote the first Sherlock Holmes novel to be endorsed by the Conan Doyle Estate; titled The House of Silk, it focuses on two different cases that are oddly linked. He followed up with a separate story based in the Holmes universe; Moriarty. He also wrote the James Bond novel Trigger Mortis and its followup Forever And A Day, making him the first author to write more than one Bond novel since Raymond Benson.
His 2016 novel Magpie Murders and its sequel are Christie pastiches with a meta twist. Daniel Hawthorne Novels are another series of metafiction murder mysteries, which also feature Horowitz himself as The Watson.
