This book has Kay working a crime scene in Cambridge. At some point, Kay gets some CCTV footage that appears to be from Lucy, but is of Lucy. Kay is alarmed by what she sees and the secrets Lucy has. Yawn. Lucy is always doing something she should not be doing. I cannot stand her, and that is a well established fact, but she is always doing something she should not be, with people she should not be. There is nothing new about it. Kay, of course, is self-absorbed and cannot imagine how many things she does not know about these people she is close to, and she just simply doesn't know who to trust. Does she ever know who to trust? I sincerely hoped that Lucy would vanish from this series by now, but I have resigned myself to the fact that we are never going to get rid of her. We also have to endure descriptions of her estate and her cars, as if one really cares. This was just a rehash of events, basically, and the reemergence of two people that should have been out of this series many books ago. I am disappointed thoroughly.
