This is a real gem of a book. It was recommended to me by a friend and the very next day I found a 1938 Penguin Edition staring out at me in the second-hand book store. For the 50cents it cost me, it was one of the best reads in my life.
Von Rintelen was a German Naval Officer in WWI and was one of those cobbled together in desperate times to work on espionage eassignments all over the world. Speaking either North American or British English, he could disguise himself effortlessly as a businessman interested in buying armaments for the western allies in New York. While America was still neutral Von Rintelen planted bombs on transports and munitions ships, disseminated false imformation, and even organised his own labour union (inviting US congressmen to speak at some of its conventions) all usually with the help of disgruntled Irish Americans wanting to help cripple the English war effort. All the while he established a string of false companies to buy and trade in NY.
The vignettes are incredible and worthy of a hollywood thriller. He ends up at a hotel party in Massachussets and finds out that the British Naval Attache assigned to look for him is attending the same party that night. Von Rintelen, decides right away to join the party and introduces himself to the British Attache as .... of all people... a British Naval Commander sent from London on special assignment to apprehend this Von Rintelen chap! (Really himself). Of course without instantaneous email or transfer of pictures over the wire, the British Attache has no idea that he is indeed talking with Von Rintelen (hillarious!), while Von Rentilin, over drinks, proceeds to draw out all the information British Naval Intelligence know on hilself.
He was eventually arrested in the Channel while on a Dutch Liner heading back to the country disguised as a Swiss National.
This is WWI and the ruthlessness of later wars is not present. His opponents are mainly honourable "genetlman" where he enjoys the commraderie of other English Officers whilst in confinement in England. His first glimpse of "democracy" happens when he is shipped back to the US as common spy (despite the fact that this may have been technically illegal under international law --- even at the time) and incarcerated in Atlanta until 1921. That he only got 4 years for espionage and sabotage is a interesting indication how far the US has come: in 1917, during wartime,they gave German Spies guilty of espionage & sabotage 4 years in jail. In 2002 the US is executing teenagers and the mentally handicaped for capital crimes -- progress?
His descriptions of Southern Jails is also interesting and his empathy with the criminals is an interesting refrain for this German gentleman.
A highly interesting and fast paced book that should be made into a movie.
