When hero policeman Grant Cliveden dies from a poisoning in the Old Bailey, it threatens to shake the country to its core. The evidence points to one man.

But it will quickly become clear that Jimmy Knight is not the only person in Cliveden's past with an axe to grind. The only thing that's certain is that this is a trial which will push Adam - and the justice system itself - to the limit.
