With a background in construction and heavy industry Socialist academic John Tully ( a lecturer in Politics and History at Victoria University) has, as the bibliography below indicates, a serious interest in South-east Asian history, and given the Cambodian content (with rubber as a significant Cambodian export) it probably comes as no surprise to learn he's curently (or was, according to the ubiquitous Wikipedia) working on a social history of the city that processes around half the world's rubber (Struggle City USA: A Social History of Akron, Ohio). Hopefully, on the basis of Dark Clouds on the Mountain, he'll have a chance to bring out some more fiction as well.
