Deed presides over a murder trial. An old man suffering from cancer died from a morphine overdose, and his attractive young woman doctor has been charged with murder, on the accusation of the dead man's niece. The doctor is acquitted, following a patholigist's evidence that the cause of death was beta blockers in the medication building up in the old man's liver, so the increase in dose from 50mg to 200mg had not affected the outcome... But then the doctor comes to Deed and confesses that she intended to kill her patient. When the Lord Chancellor's Department gets wind of this development, they suggest Deed was sleeping with the doctor - but with Jo's help, he is able to neutralize this threst.

After a young woman is battered to death, the mentally retarded Gary Patterson confesses and the police consider the case solved. However, Gary later withdraws his confession, leaving Judge Deed's court struggling with limited evidence.Meanwhile, Deed is also busy looking into a case about a multi-million pound mortgage fraud and comes up against a masonic conspiracy. The fraud case is due to go before a brother judge who himself proves to be implicated, and who commits suicide. In Deed's own court, the jury finds Gary Patterson not guilty, Deed asks who the killer was, and Gary says he witnessed the killing and knows the answer.
