Adrian Dawson (born 26 January 1971) is a British author of thriller and horror fiction, currently best known for his 2010 debut novel Codex. Codex was written in 1999, and Dawson was signed to the Christopher Little Literary Agency on the strength of the novel, but they failed to find a publisher. Codex deals with cryptology, religion and high-end technology, with one publisher stating that most readers would turn to non-fiction, rather than fiction for such subject matter. However, with the advent of the iPad, Dawson's novel was published in ebook format where it achieved a place on the UK iBookstore's Best Seller list and was printed in November 2010.
