Occasion Beneath The Skin
Nicci French

Zoé, Jennifer and Nadia are three women with nothing in common except the letters they receive each one full of intimate details about every aspect of their lives - from the clothes they wear to the way they act when they think they're alone. And if that isn't terrifying enough, the letters also contain a shocking promise: that soon each life will come to a sudden, violent end. Can Zoë, Jennifer and Nadia discover who their tormentor is? And if so, will any of them live long enough to do anything about it?
