Guy Adams trained and worked as an actor for twelve years before becoming a full-time writer. If nothing else this proves he has no concept of a sensible career. He mugged someone on Emmerdale, performed a dance routine as Hitler and spent eighteen months touring his own comedy material around clubs and theatres. He is the author of the best-selling Rules of Modern Policing: 1973 Edition, a spoof police manual 'written by' DCI Gene Hunt of Life On Mars. Published by Transworld, it has sold over 120, 000 copies. Guy has also written a two-volume series companion to the show published by Simon & Schuster; a Torchwood novel, The House That Jack Built (BBC Books); and The Case Notes of Sherlock Holmes, a fictional facsimile of a scrapbook kept by Doctor John Watson. Carlton Books published it in 2009 in association with the Estate of Sir Arthur Conan Doyle, to celebrate the 150th anniversary of the writer's birth.
