A spy for all seasons: the early career of Baron August Schluga von Rastenfeld, 1866-1890

Baron August Schluga von Rastenfeld is considered by most historians to be the most successful spy of the late nineteenth century. Yet very little is known about the man or his work as a German secret agent. Until recently it was believed that the destruction of all documentary evidence of his exploits meant that this void could never be filled. However, this study has uncovered new material that provides important insights into the achievements and methods of this master spy. It also serves as a representative case study of the general conduct of espionage in the decades preceding the First World War.
