A popular account by a New Zealand writer, assisted by a Paris reporter for the International Herald Tribune. French agents conspired to sink the Rainbow Warrior in order to prevent the Greenpeace boat from observing and reporting on scheduled nuclear tests in the Pacific. A dramatic tale, told without identifying sources, of what came to be called France's Underwatergate. A sympathetic picture of Greenpeace with its continuous efforts to stop nuclear testing and protect the threatened environment. A good mystery story, with the villains the inept agents of the French secret service.
