Zone Policeman 88, A Close Range Study of the Panama Canal and its Workers, By Harry A. Franck, Zone Policeman 88: A Close Range Study of the Panama Canal and Its Workers is a non-fiction book written by Harry A. Franck and published in 1913. Franck, a travel writer who had produced a highly successful 1910 travelogue, Vagabond Journey Around the World, took a position as a police officer in the Panama Canal Zone, reporting his experiences and observations in a book that proved, like his debut, popular. The book was generally critically well received. Franck, who had supported himself as a teacher prior to the success of his first travelogue, took a three-month job on the Canal Zone Police force, helping to patrol the workers assigned to the Panama Canal Zone. There, he helped keep peace as plain-clothesman but also served administrative duties, including as a census enumerator.
