Sigh...
So this book was off to a tremendous start. It's not so much of a "whodunnit" so much as a "whydunnit" as the killer and victims are revealed on page 1.
I liked how the story unravelled, showing quite clearly how the nanny (Louise) seem to be losing her tenuous grasp on reality. Her complete disinterest in her own life and her obsession with that of her employers and their children. There were some weaknesses, especially in how blind or hopeless the parents appeared to be without any reason why. The scene with the chicken carcass would have surely ended in the nanny being fired in a normal household. The parents fear of the nanny never made sense.
However these small annoyances could have been forgiven if not for the book's biggest flaw: The end. It felt as though the author... gave up....
She started to suggest reasons for the murder, the nanny's obsession a new baby perhaps and wanting to remove any potential obstacles but then she STOPPED. Gave up. Why was the nanny in a coma? Why did she do it? Who knows - the author evidently didn't know or didn't care to disclose. Which is a shame. Had the novel ended properly it would have been a solid 5 from me. As it is, if you do choose to read this book, prepare to be left feeling very unsatisfied in the end.
