John Williams was born in Cardiff in 1961. He wrote a punk fanzine and played in bands before moving to London and becoming a journalist, writing for everyone from The Face to the Financial Times. Following Into the Badlands, his book Bloody Valentine, about the Lynette White murder case in the Cardiff docks, provoked a libel action from the police. His novels include the London-set Faithless, and The Cardiff Trilogy. He now lives in Cardiff with his family.
