A friend good reader like me advised me this book by saying it changait usual pollars ... and actually it changes. Finally a real thriller with a real serial killer where every noise at night at home worry you and makes you go around the house to check that everything is closed! ^^ And yes, I know, I found myself very stupid. The author knows how we get into the story from the first page. And doubt sets throughout the narrative. I now look forward to reading the second installment of the trilogy that promises pationnante !!
