Complicity is a novel published in 1993. Its two main characters are Cameron Colley, a journalist on a Scottish newspaper called The Caledonian, which resembles The Scotsman, and a serial murderer whose identity is a mystery. The passages dealing with the journalist are written in the first person, and those dealing with the murderer in the second person, so the novel presents, in alternate chapters, an unusual example of an unreliable narrator. The events take place mostly in and around Edinburgh.
Colley is a "Gonzo journalist" with an amphetamine habit, living in Edinburgh. He also smokes cigarettes and cannabis, drinks copious amounts of alcohol, plays computer games, and has adventurous sex with a married woman, Yvonne. He regrets his addictions and misdemeanours and tries half-heartedly to give them up occasionally.
He reflects on his awful experience of witnessing the aftermath of the massacre at the 'Highway of Death' in the Gulf War, and covers the deployment of HMS Vanguard, Britain's first Trident nuclear missile submarine.
