Marina Katos’s body is found in a park and the police don’t seem to know or care who committed the crime. In a haze of tranquillisers, hallucinogens and Valium, her best friend Felix McAveety decides to solve the murder. To break through his drug-induced fog and get closer to the truth Felix enlists the help of a dying crime novelist, Jane Pickford, and his crisis-ridden friend Donnie. Their quest takes them into the dark heart of Scottish politics, the orbit of drug dealers, and the matrix of AI, encountering Independence activists, the intelligence services and stalkers, as they seek justice for Marina.
