after his previous album on Yersin ("the plague and cholera") that reached its height, I wondered how Patrick Deville was going to surprise me? and if there was going to happen? ... I admit I am very impressed with the book of Deville, scholarship summit, following Trotsky and Lowry (and many others) in their Mexican wanderings. the work accomplished by Deville is amazing (see his bibliography, just that already ...) and to hover at such altitudes, guaranteed 100% free book Mezcal or peyote ... however a remark as outlined in the previous comment If you do not have solid references in contemporary history (circa 1920 to 1950), go your way, the book will seem without interest as cultural occurrences are sharp ... otherwise enjoy! good reading ...
