In Mick Herron’s sharp, darkly funny espionage novel, a group of disgraced British intelligence agents at Slough House is drawn into a web of old secrets, political games, and dangerous loyalties when a long-buried Cold War mystery resurfaces. Gritty, sardonic, and tightly wound, Dead Lions blends suspense and black humor in a world where incompetence can be deadly and no one in the intelligence service is quite what they seem.
