Tony Quirke is the sort of person you see travelling to work on the London Underground and don’t pay much attention to – thirty-something, middling sort of job in the City, interested in beer and rugby. One day he’s called for jury service on a murder trial.

His fellow jurors are convinced that the young man in the dock is a heartless killer.

Tony disagrees. He doesn’t think the prosecution case stacks up, so after the defendant is convicted on a majority verdict, he goes looking for evidence the police missed.

One by one he peels away the layers of corruption that conceal the truth.

But his quest takes an unexpected turn, raising demons from his past and forcing him to confront the question of which side of the law he’s really on.
