Summary justice

The last time Tess de Vere saw William Benson she was a law student on work experience. He was a 21-year-old, led from the dock of the Old Bailey to begin a life sentence for murder. He'd said he was innocent. She'd believed him. 16 years later Tess overhears a couple of hacks mocking a newcomer to the London Bar. That night she walks back into Benson's life. A desperate woman has turned to him for help: Sarah Collingstone, mother of a child with special needs, accused of slaying her wealthy lover. It's a hopeless case and the murder trial, Benson's first, starts in 4 days. The evidence is overwhelming but like Benson long ago, she swears she's innocent.
