Magpie Lane / Lucy Atkins.

There's a stranger upstairs . . . you let her in. Felicity, the daughter of an Oxford College President, has gone missing. A silent and lonely eight-year-old, she lost her mother when she was just four. When her glamorous stepmother hires Dee, an experienced and clever nanny, everything changes. Dee is powerfully drawn to the neglected child, but nights in the 500 year-old President's Lodging soon become fraught as Felicity is haunted by nameless terrors. Nobody realises that Dee has demons of her own, but when Felicity vanishes, the police suspect that she knows more than she'll admit, and a complex battle of wits unfolds.
