The final two chapters of this part.
Laptop batteries generally aren't hazardous, I exaggerate for the purposes of my story. A few years ago, though, there were indeed some reports of batteries actually catching on fire, though not exploding. There was also the Boeing plane model that had major problems with the batteries of onboard computer systems. So the thing is, I didn't go so far afield with that aspect of A.I. Bear in mind that Spook's actively involved as an "inside" saboteur of Carlos' portable. The result isn't at all far-fetched. Batteries actually can blow up if subjected to electrical power surges; a chemical reaction-the same reaction that, controlled, allows them to store electrical current and dispense it on demand-can produce such a catastrophe. If you've ever made a mistake in jumping a car battery, reversing the poles, you may have seen the beginnings of such a thing: the jump wires, and the battery terminals, will quickly generate a lot of heat which, if allowed to go on, can lead to some kind of abrupt collapse of the batteries' interiors.
Well. Thanks again to the many who've loyally stayed with me. There's one more part to go, but it's only a few chapters. We're coming up on the end of the novel, which may come as something of a surprise to many of you who've e-mailed with thoughts of where this story might go.
