Query: Disappointed after A Simple Plan

Ordinarily, I might give this book about 3 stars. But I probably have to downgrade this because my expectations were so high after A Simple Plan, which I adored. Perhaps that's not fair. Certainly, this book is a page-turner - I had to keep reading it and reading it until I got to the end. But, unlike A Simple Plan, this went from a potential real-life situation to surreal horror - you really have to be able to suspend disbelief. To the point that it's just not credible. To me, that marred Smith's fantastic sense of story-telling. He really is a good writer, and he certainly did well with the subject matter he'd chosen. But I just couldn't buy the premise, and that somewhat ruined it for me. Sorry!
