Glasgow, 2015. When Valium addict Felix McAveety's best friend Marina is found murdered in the local park, he goes looking for answers to questions that he quickly forgets. In a haze of uppers, hallucinogens, and diazepam, Felix enlists the help of a brilliant but mercurial GP; a bright young trade unionist; a failing screenwriter; semi-celebrity crime novelist Jane Pickford; and his crisis fuelled downstairs neighbour Donnie. Their investigation sends them on a bewildering expedition that takes in Scottish radical politics, Artificial Intelligence, cults, secret agents, smugglers and vegan record shops.
