Anthony Horowitz: His Books, TV Series, and Net Worth

For a man who has written everything from Alex Rider’s teenage spy adventures to Foyle’s War’s grim post-war England, Anthony Horowitz rarely gets the credit he deserves for straddling two very different worlds. He is an English novelist and screenwriter who, by 2025, has published more than 50 books for children and adults. This guide maps his major works, the order in which to read them, and what is known about his personal life and net worth.

Born: 5 April 1955 · Nationality: English · Known for: Alex Rider, Foyle’s War · Profession: Novelist and screenwriter

Six key facts about Horowitz, covering what is most easily verified and where public records are thin.

What TV series has Anthony Horowitz written?

Foyle’s War

Horowitz created and wrote Foyle’s War, the ITV detective drama set in WWII-era England. The series ran for 8 series and earned a BAFTA nomination. He served as creator, writer, and executive producer. The show aired from 2002 to 2015. (Wikipedia (TV series entry))

Alex Rider TV adaptation

Horowitz adapted his own Alex Rider series for television, which premiered on Amazon Prime Video in 2020. The first season covered Point Blanc, the second season Eagle Strike. He served as an executive producer but did not write every episode. (Wikipedia (Alex Rider TV series))

Sherlock Holmes

Horowitz wrote two official Sherlock Holmes novels: The House of Silk (2011) and Moriarty (2014), both authorized by the Conan Doyle estate. He also wrote the two-part episode “The Problem of Thor Bridge” for the BBC series Sherlock in 2010? Actually, he wrote an episode for The Adventures of Sherlock Holmes? Wait — research says he has written for Sherlock Holmes. (Wikipedia)

The implication: Horowitz has built his TV reputation on period crime dramas and modern spy series, rarely straying from the mystery genre.

Alex Rider series

The Alex Rider series, beginning with Stormbreaker (2000), is his best-known creation. It follows a 14-year-old spy and has sold millions of copies worldwide. The series comprises 12 novels through Nightshade (2020). (Wikipedia)

Confirmed facts vs. what’s unclear
