Detective Zhong Fong has regained his position as head of Special Investigations in the Shanghai district. He is back in the city that he loves with his new wife and baby girl.

All seems to be going smoothly - until one of Shanghai's state-run abortion clinics explodes in a ball of flame. A note is left in English. Then a second clinic is attacked, and a second note found. It reads, 'This blasphemy will stop - the light will come.'

Fong's investigation of the bombings will lead him deep into a place he knows all too well: the darkest recesses of the human heart.
