Daisy Schults, aged 11, has disappeared. Her professor mother is numb with grief; the two police officers (disappointingly, one a hardened pro with a collapsing home life, the other an eager young rookie) have few leads to work on and the increasingly hysterical words of an unreliable witness to wade through. The witness also knows the waitress who serves one of the police officers his daily excess consumption of alcohol. And there we have it: five helpless people, buffeted by London living.
