Anthony Horowitz, OBE is an English novelist and screenwriter specialising in mystery and suspense. His work for young adult readers includes The Diamond Brothers series, the Alex Rider series, and The Power of Five series.
Traditionally, the canon of Sherlock Holmes consists of the 56 short stories and four novels written by Sir Arthur Conan Doyle. In this context, the term "canon" is an attempt to distinguish between Doyle's original works and subsequent works by other authors using the same characters.
