A contemporary psychological thriller in the style of Ruth Rendell, from one of today's most versatile and compelling storytellers.

It was easy for Elizabeth. She married the man she loved, bore him two children and made a home for him which was the envy of their friends.

It was harder for Ruth. She married Elizabeth's son and then found that, somehow, she could never quite measure up...

Isolation, deceit and betrayal fill the gaps between the two individual women and between their different worlds. In this complex thriller, Philippa Gregory deploys all her insight into what women want and what women fear, as Ruth confronts the shifting borders of her own sanity. Laying bare the comfortable conventions of rural England, this spine-tingling novel pulses with suspense until the whiplash double-twist of the denouement.
