Camp 020: M15 and the Nazi Spies
The idea behind the book is very attractive.
There was a great potential to supply, from such sources, historians with rarely known facts on some of the less known (but essential) nazi criminals.
Unfortuntely the work is, for the uninformed, boring and, for the confirmed historian, shallow. Furthermore it is narcissic and opinionated instead of factual.
Having studied the full interrogation reports on some of the assassins handledd in this camp and their full defense files, it turns out that camp 020 did in fact a poor job and the authors don't really realize it.
The authors' only excuse is that each of the files is so complex that it would probably require a series of books. The synthetic book form may not be suited to a subject where everything is in the details, the subtlety of the lies, the distortion of information...
There was not much subtlety in the Camp 020 interrogations (most of their lies are mostly by omission), and there is no subtlety in this book.
Sadly, a wasted opportunity: this book remains to be written (maybe with less cases but with a proactive analysis on the shortcomings of the interrogations themselves).
