The book was originally German, and this English translation was also developed and printed in Germany. It has slightly bizarre typesetting, using guillemots in place of quotation marks (except in one place in the preface, where a mixture was used), inward-pointing opposite of the way the French use their guillemots. Also English hyphenation rules break words on syllables, but here the hyphenation was done at any letter, hurting readability a little bit. There were also basic proofreading mistakes throughout which caused the book to seem a bit silly at times. The publisher should have worked with a USA firm for the English release, or at least had more native English speakers assist in the production. But, I'm sure this can all be explained in trying to hold down costs. Okay fine, the damage is by no means fatal to the product. The type style and layout, however, were exceptional. It was a joy to handle this hardcover edition.
On the book's subject, technical details were a little sparse, but not totally absent. It reads more like a business & industry book, except the players are niche and generally secretive, but no less rapacious at times. *wink* Lots of fun anecdotes throughout. The chapter near the end discusses the US $100 supernotes, and provides a *very* compelling case that the CIA was and is their source, not North Korea, as promoted in American media. This part of the book was actually my favorite! This section presented a key detail that absolutely 100% of their visual features were perfectly copied, making manual, human-based counterfeit detection dang near impossible. However, automated banknote validation equipment for the US market could and did, at the same time, instantly reject 100% of the supernotes. So...While USA users were are are scared by media that North Korea could be attacking and contaminating the money supply, USA domestic users of the cash had basically -zero- to worry about. Just as soon as any (unwitting or not) supernote user made a deposit to their regular bank, they'd be getting a call and perhaps a brief interview from a secret service agent or other investigator. Since the vast majority of American consumers, and basically all American business, re-deposit received cash quickly, any supernote injection would be flagged and pulled about as fast as it would land ashore.
For the CIA, paying for covert ops (almost certainly of dubious moral/ethical/legal repute) this way seems rather a ingenious move. I'm sure there must have been other use-cases for supernotes thusly designed, too. You could get them into the hands of someone suspected of being part of some terrorist network, and then watch reports come in from banks about counterfeits being rejected to see where the network stretches, who their suppliers or partnering organizations are, etc.
The book didn't say, but I'm reasonably confident that inter-government agreements could have shared supernote detection measures such that coordinating governments could exercise some control over where supernotes pop back out of the system of hand-to-hand cash. Then the only way to stay under cover would be for introduced supernotes to /never/ return to the international banking system, but remain as hand-to-hand cash. The more modern/technically enriched/1st-world you go, the less practical it seems that you'd keep your liquid assets as physical cash and not utilize banking services.
The story reminded me of the time during Iraq War 2/Afganistan-perma-war that US news outlets were reporting stories about the Defense Department being basically un-auditable, and that the Pentagon had even lost track of some $2 bln. in palletized cash for transport that was "supposed" to be for ATMs at US bases overseas. What? Maybe the lost cash consisted of CIA supernotes, and by "lost" it was actually a cover story to help inspire foreign users of US cash that the new cash finding its way into their midst was genuine, the US was concerned over losing it, and they'd be silly not to regard it as good money for their own uses.
Why not?
The truth is probably stranger than fiction on this.
