Pursuit is the autobiography of a Mountie who rose from Royal Canadian Mounted Police's lowest echelon to become its Commissioner. Previous to his joining the Service, Rivett-Carnac's life was jammed with extraordinary adventures. Among others, he drove an ambulance under German fire in World War I, ran some elephant camps in India, and took charge of a lime manufactory at far-off Bisra. He dissuaded himself from joining the Foreign Legion because of his malaria. Finally, in his middle twenties he emigrated to Canada and immediately joined the Mounties. Then followed seven years in the North's utter desolation and incredible journeys over snowbound wastes, during which he pursued every manner of criminal. Beside enforcing the law, his job was to check on the most isolated trappers who lived fantastic distances apart--not unusually these men went mad or sometimes murdered a companion. He was eventually transferred to a departmental job and promoted to officer rank. His greatest case was an Assistant Commissioner, during which he set up the net which captured a Soviet spy ring. This was the famous Igor Gouzenko case which alerted North America to the fact that the Soviet Union had obtained some of the West's atomic secrets. Rivett-Carnac is quite modest but his story is unfailingly gripping.
