The same day as suicide bombers shock London, dentist Anthony Price is involved in an accident at a swimming pool that shatters the routine of his existence. Pushed off the top dividing board by an unruly adolescent, he falls on a beautiful Thai girl in the water below, cracking one of her front teeth. In the aftermath, Price gets to know the girl, first as his patient called Sisira, then intimately as an escort called Sonia. Blinded by desire for her, he fails to see the trap he is walking into and falls headlong into a nightmarish world of blackmail and murder from which he may never truly escape. Totally compelling and terrifyingly convincing, Sisi & Sonia is the story of how an ordinary man can go to extraordinary lengths to win the heart of a woman who has lost all faith in men.
