Zoe, a pretty blond schoolteacher. Jenny, a former hand model turned model wife and mother. Nadia, an irrepressible free spirit who entertains at children's parties. Three women living in different parts of London, grappling with different problems, sheltering different dreams--their lives and narratives linked only by the singular madness of a sadistic stalker. As they move slowly through the sweltering heat of summer, someone is sending these women letters that let each know she is being watched, studied, and loved from afar--even unto death.
