Difficult to pigeonhole this one. Told in 3 parts, it is the two sides of the story, then the ending. It's the story of a marriage, and on that's gone off the rails - the course of true love hasn't quite run smooth. I'm sure most people can relate to that - marriage has it's lumps & bumps & needs to be worked at. However, few of us have to ddeal with a bump the size of being framed for your wife's murder. That's what happens to Nick. Amy has vanished, there are signs of stuggle at the house and she's gone. They've been having trouble recently and slowly the evidence mounts against him. An affair comes out and is yet more fuel to the fire. He's not helped by the publicity circus that surrounds the case, being a reserved character, who buckles down & copes - stoic springs to mind. One of the detectives has her doubts, but the case gradually builds and he's arrested and due to be brought to trial. Then the scene shifts and you discover that the image of Amy you've had in the first section is fabricated by Amy herself. Then the back story fills in and you find that she's not the innocent little wife, she's actually quite a nasty piece of work and comes to entirely believe her version of events. She has planned the entire thing, and it's only that she gets herself into trouble that causes the story to play out differently. This starts to exhonerate Nick from some of the more major charges against him - the affair and the lack of care are not excused though. The ending has the pair of them both playing at being the in love couple they once were, but it's a high stakes game.The book has so many twists and turns that you wonder what sort of mind came up with this. It kept me going, as you want to know what happens next, but are half afraid to find out. I felt that Nick was the more real of the two - Amy was just so far out of left field that she was almost a charactature. That's not to say he didn't have his faults, but they were faults of human falibility, rather than being deranged.
