My friends did warn me this book tends to mess with your head. I tried to stay ahead trying to guess what the twist was, who the killer was.. It dint work. Not very surprised by the ending. I only feel I should have know better. But the way everything was presented by the author I didnt have a chance . 
 The book is a good read. You wont be able to keep it down once you start. It sort of carries you away with it. The way the trial was presented it reminds me of all those cases where the defendants go to jail for exactly the reasons shown in this book. But the ending... (view spoiler)[well looks like justice dint prevail. 
 But I dont think I would have been happy if Derrek had managed to convict Anna with the evidence available now that I know she killed Elsie. I would have wanted her to go down without there being any doubt. So it looks like psychopaths really know how to get away with murder. (hide spoiler)]
