When the eight-year-old daughter of an Oxford College Master vanishes in the middle of the night, police turn to the Scottish nanny, Dee, for answers. 

As Dee looks back over her time in the Master's Lodging - an eerie and ancient house - a picture of a high achieving but dysfunctional family emerges: Nick, the fiercely intelligent and powerful father; his beautiful Danish wife Mariah, pregnant with their child; and the lost little girl, Felicity, almost mute, seeing ghosts, grieving her dead mother. 

But is Dee telling the whole story? Is her growing friendship with the eccentric house historian, Linklater, any cause for concern? And most of all, why was Felicity silent? 

Roaming Oxford's secret passages and hidden graveyards, Magpie Lane explores the true meaning of family - and what it is to be denied one.
