What is Anthony Horowitz famous for?

The character of Sherlock Holmes was originally created by the Scottish writer Arthur Conan Doyle, who featured him in four novels and more than 50 short stories. After his death, his son Adrian wrote several stories featuring the famous Victorian detective, but critics say he was never that popular. But it’s the first time that the Arthur Conan Doyle estate has officially asked an author to write a new novel. He has been named as Anthony Horowitz and is best known for his Alex Rider children’s series.
