The Truth About the Wonder Weapon is a book about the weapons of the Third Reich that were intended to serve as a last resort, yet differ from all other weapons. The author, a former military journalist, presents the results of his research conducted in the archives of many countries across three continents, providing a wealth of facts about weapons and technologies that the public has never heard of before. This book is very well documented, with most sources having never been described in any previous publication. The analysis largely focuses on a research project aimed at developing a weapon that still eludes any classification: the wonder weapon or, according to German documents, a weapon decisive for warfare.
