Devastated by the shocking news that an old schoolfriend, Suzy Palmer, faces execution in Louisiana for the murder of her children, London rabbi, Deborah Hirsch, enlists the aid of her former classmates in an attempt to get her off. The Suzy they've known and loved all these years could never hurt a fly; she can't be anything but innocent.
As adults they all have high-powered careers - Lisa Maguire, the eminent QC; Helen Kruger, the Harvard anthropologist; and Olivia Fernshaw, actress and mimic, only allowed into their exclusive group when poor Miranda dropped out. Aided by Miss Holbrook, Suzy's feisty former art teacher, and Markus, the German jazz musician who is Lisa's latest flame, the friends unite the beat the clock as Death Row draws steadily closer.
Back and forth across thirty years they slowly piece together what has happened - and realise that even more shocking than Suzy's plight is the knowledge that one of their number has betrayed her.
