This is my first book by Matthew Klein - a thriller set in the world of IT companies that have overstretched (so far anyway).
From the Blurb:
Jimmy Thane knows all about crossroads. Every time he's been faced with one he's taken the wrong path. At the peak of his career, he chose alcohol. When his job became shaky, he turned to drugs. And when his wife lost faith in him, Jimmy went looking for other women. Now Jimmy's clean and he's at a new crossroads. He has one last chance to save both his career and his marriage -he has seven weeks to turn round a failing company. In return, Jimmy lands the job of CEO and he and his wife get to start over. This time he knows which path to take.
Except, from the moment he enters the building, he senses there's something very wrong -the place is too quiet, too empty. When the police come calling about the disappearance of the former CEO, Jimmy begins to wonder what he's got himself into. Then he discovers surveillance equipment in his neighbour's house, looking straight into his front room. And he begins to notice that his wife isn't just tired, she's terrified and trying to hide it.
Nothing is as it seems. Jimmy no longer feels like he's living the dream -instead he's plunged into the worst kind of nightmare there is. And when he finally gets to the truth, it's more shocking and terrifying than you could ever imagine.
