1981, Glasgow, Scotland: The McLachlan family have dominated the criminal underworld for more than a decade. Masters in extortion, murder and heroin trafficking, they hold the city in their iron fist. But a war is coming to Glasgow; a war unlike anything the McLachlans have known before. Over the course of one night, they will discover the wrath of one man - Gorilla Grant, former spy and now freelance assassin. And Gorilla Grant plays by his own set of violent, unforgiving rules. James Quinn's Gorilla Warfare is a hard-bitten crime novella about redemption, revenge and the evil that men do.
