My Secret Service, By the Man Who Dined with the Kaiser 

What would happen if a man went undercover into enemy territory during World War One? One man ventured to find out. The book’s unnamed narrator, a Daily Mail journalist, begins his journey posing as a steel worker in Essen, before being 'dismissed with ignominy’ and moving on to Constantinople. The journalist, who at the beginning of the book, proclaims 'I am not a spy’, undertakes a covert journey through the Balkans, Turkey and Asia Minor, detailing the state and effect of the German presence. In Turkey, he gains an audience with the leader of the Ottoman Empire, Enver Pasha. He is also fortunate enough to dine with the Emperor of Germany in Nish, lending this claim on fame to the front cover of his book. (Amazon)
