Matt McAvoy is an English horror writer and criminologist. It was this work within the Criminal Justice System that inspired him to become a writer. His first book, The Black Line, gained him a cult following online and earned him a legion of online fans. Granjy's Eyes is truly dark and disturbing, and shows the authors insight from working with dangerous adult offenders and captures the inner psychological conflict of a psychopath, something not properly narrated since The Wasp Factory. Matt lives with his wife Katherine in London.
