This book is unputdownable. Crime fiction is often predictably macho but this one combined an artfully constructed plot with a raw and plausible account of a young mother's psychological torment. It kept me guessing until the very end. The fact that it is narrated, at breakneck speed, by the lead character, Jess, draws you into her slightly paranoid mindset and makes you suspect, along with her,that anyone and everyone might have some involvement in the disappearance of cherubic baby Louis. It made a refreshing change to unravel the crime in the company of a vulnerable (and eminently fallible) young woman, instead of the usual gritty/flawed/recovering alcoholic detectives that crime fiction is littered with. I can't wait for her next book.
