Lullaby

by Leila Slimani
A psychological thriller where we learn from the first page that two children have been killed by their nanny. We spend the rest of the book examining how she got there and the effect she had on the family she worked for. It is well written and keeps a tension throughout but, and for me it was a big but, I don't think we will ever know. Maybe this was the point, as it is echoed by the detective on the case. The frustration of modern fiction. No escape from the real world! 7/10
