A gruesome discovery at an aircraft hanger leads Albert Campion into a turbulent mystery set in Cambridge in the middle of the Cold War. "Ripley again marries a crafty plotline with a persuasive evocation of Allingham’s style and characterizations. Fans of the originals will be delighted"- Publishers Weekly Starred Review “I have often said that my wife is a constant surprise to me.” Cambridge, 1965. The honorary doctorate ceremony for Albert Campion’s wife takes a dramatic turn when Lady Amanda is arrested by Special Branch for breaking the Official Secrets Act. Never before having taken much interest in his wife’s work in cutting-edge aircraft design, Mr Campion sets out to discover more about the top-secret Goshawk Project in which Amanda is involved. He quickly realizes he is not the only one keen to learn the secrets of the project. When a badly mutilated body is discovered at the Goshawk Project’s hangar – the result, it would appear, of a bizarre accident – Campion is drawn into a turbulent mix of industrial espionage and matters of national security. And as he attempts to get to the bottom of the deadly goings-on, it seems that the bicycles and punts are almost as dangerous as the aircraft . . .
