Nazi refugee turned Gestapo spy

the long version

"Why would a journalist who was an ardent socialist and an anti-Nazi during the waning years of the Weimar Republic decide to go to work for the Gestapo abroad? Hans Wesemann, a veteran of World War I and a successful journalist, fled his native Germany in 1933 after writing a number of anti-Nazi articles. Once in Britain, he found life difficult and dull, and thus, for a number of reasons, agreed to furnish the German Embassy in London with information about other refugees. Inevitably, Wesemann became ensnared in his own treachery and suffered the consequences."--BOOK JACKET.
