This book appears to attempt capitalize on recent interest in SS-Gruppenfueher (General) Heinrich Mueller's career, particularly noted in the series of books by Gregory Douglas based on primary sources available since the early 1990s (to Douglas, at least). This book reads well, but is not referenced in a manner that will be useful to readers who prefer documentation (and yes, there are publishers who allow it!). For the general reader, who isn't interested in such distinctions, it may be a good read, but absent any analysis of Mueller, his career, or recent findings, the book fails to hit its intended mark.
