Will I love Magpie Lane?

I love reading novels set in Oxford, where I spent some of the happiest years of my life, and this book includes some vivid descriptions of the city and its environs.

The narrator is an eccentric woman, a mathematician with a troubled past, who works for academic families as a nanny. She takes a post with an unlikeable couple in the hope of befriending their withdrawn 8-year-old daughter. But when the little girl goes missing, the nanny comes under suspicion. This is an unusual story with some quirky characters.
