Santini goes on trial at the Old Bailey accused of the murder of Jessica Orton, but tries to talk to CIB and implicate Quinnan and Rawton. A prison guard tells Santini that Sherman's drugs charges are being dropped in favour of conspiracy to murder Santini and Fox, who turns up dead in her hotel room after an apparent suicide. With Ferguson executed and Timpney taken on side by Sherman's heavies, Santini's trial starts falling apart. Hagen is discredited by her Sun Hill colleagues when she lies under oath and breaks down in the witness box after being caught out. With Santini found not guilty, he is warned by his recently released cellmate that he is in grave danger from Sherman's heavies.
