This was an engrossing psychological crime thriller that was hard to put down. Unusual in that you know who the culprit is from the opening prologue which is a transcript of his trial but still utterly "edge of the seat stuff". I've often wondered how women get sucked into these abusive relationships and why they can't leave. Well this book shows you exactly how it can happen. The characters are very cleverly developed. I particularly enjoyed the interviews with the author at the end of the book. Just great for my crime fiction writers' group.
