Dr. Jennifer White had a stellar career as a hand surgeon until early onset dementia forced her into retirement. Her best friend, who lives only a few doors down, is murdered and Dr. White is a prime suspect. There is no evidence of forced entry or struggle and the victim is missing fingers from one hand. There were expertly removed, even Dr. White commends the work when she is shown the pictures. However, she keeps forgetting that Amanda was killed, as she keeps forgetting everything. Dr. White's son and daughter are alternately a support and an annoyance to her as they struggle with losing their mother and their own neuroses. The entire book is told from the point of view of Dr. White and it is painful and frightening to get inside the head of someone in the situation of slipping away. It is especially hard for Dr. White because she has always been such a powerful woman. If one has gone through the despair of witnessing a loved-one with dementia, this book will be difficult to read, but cathartic as well. LaPlante has achieved something very special in that she has written a work of literary fiction that is also an exciting thriller as the murder investigation unfolds.
