He left as a Nazi spy. He returned to become Hitler’s most trusted scientist. But the man who left was not the man who returned. If you are interested in the OSS, MI-6 and the untold story of a single man who changed the course of WW II in Europe, this is a book you won’t want to miss. THE RETURN OF CHRISTOPH ZELL is not a predictable “series quickie” but a standalone novel of substance, a work which cannot be written in weeks or months. Be patient! You’ll find the wait worthwhile.
