I’m a bit late with this followup but the gist of it is that the villain of the story, a female psychopath, was behind the attempt to not only off the inventor of the technology but was planning to give the technology to the Chinese so that their power-hungry leader could subjugate his people… and take over the world.
It turns out that she was able to beat the perfect lie detector despite being a psychopath: She reprogrammed the software to ignore the fact that she was lying and had been all along. But the hero of the story figured it out and exposed her plot and made a deal with her: Help him rescue his father, who’d been snatched by Chinese operatives, and he’d let her go free and with a promise not to hunt her down like the mad dog she apparently was.
The rescue was messy but successful and as the hero was taking the villain to a vehicle to complete his end of the bargain, his wife – who, let’s say, via a lie of omission – double-tapped the hussy and, as she told her husband and psychopathic bad girl, everyone else agreed to let her go… but she didn’t and couldn’t.
Throughout the rest of the story, it was debated heavily about whether the world was ready for this technology – should it be released or suppressed? They decided to release it to the whole world at once so that no one country could have an advantage, make it affordable to everyone, all that good stuff… and life goes on.
The author had a lot of interesting stuff at the end of the book; he likes to explain what’s fiction and what’s reality and that, all by itself, makes for some interesting reading given how much of what he wrote is based on factual data.
