This probably ranks as the definitive book about Mosley. It is well researched and packed with relevant information about his progression through life and through the political wilderness in which he seemed to thrive. My only real criticisms are that the "Battle of Cable Street" is somewhat glossed over in a few pages and despite the authors denial, I cannot help but feel that Mosley is seen through slightly tinted glasses. The Mosley family - including Oswald - cooperated in the writing of this book and I think this has helped sanitise some of the more obnoxious aspects of his character. The Blackshirts were, in truth, a body of semi-disciplined thugs who latched on to Mosleys populist views and this was a great excuse for a fight. Mosley himself is portrayed as "not quite" anti semitic or racist, but it is not hard to see through this façade. Otherwise I think it is an excellent and generally well balanced book.
Overall, an exceptionally informative and interesting read.
