Peri, a wealthy Turkish housewife, is on her way to a dinner party at a seaside mansion in Istanbul when a beggar snatches her handbag. As she wrestles to get it back, a photograph falls to the ground - an old Polaroid of three young women and their university professor. A relic from a past - and a love - Peri had tried desperately to forget.

The photograph takes Peri back to Oxford, where she was sent at eighteen, abroad for the first time: to her dazzling, rebellious professor and his life-changing course on God, to her home with her two best friends, Shirin and Mona, and their arguments about Islam and femininity and, finally, to the scandal that tore them all apart. Over one desperate night she tries to make sense of a past she has tried to forget - but can we ever escape who we once were?
