The M.S. of this amazing diary of a German U-Boat Commander has fallen into our hands under somewhat unusual and mysterious circumstances, the name of the writer being withheld for reasons which will be readily apparent to all who read his astounding experiences. It is, however, a story so thrilling and sensational that we have no hesitation in offering it as it stands to the public, kept so long in ignorance by the necessary evil of a rigid censorship. A particularly human and intriguing touch is given to the book by the Author's very frank account of his mad infatuation for a beautiful girl of his own country who was inextricably involved in his incredible exploits and adventures on the high seas.
