Margaret Lennox is recently widowed and in need of a position. It must be far from the past that still haunts her. She finds what appears to be the perfect engagement: governess to a child in an isolated country house. Yet from the first, Hartwood Hall is unwelcoming. Why do the locals eye her employer, widowed Mrs Evesham, with suspicion? What is hidden in the abandoned East Wing? Who are the strangers coming and going under darkness? Hartwood Hall conceals mysteries, perhaps even danger. But Margaret bears her own secret. One she fears more than anything.
