Kingdom: Season 3

Whilst Peter helps soldier Tony Gillespie, who lost a leg in Iraq, get decent compensation, Lyle acts for Tony's girlfriend Kate, who files a case of sexual discrimination when Tony's regiment turn down her application to enlist. Lyle suspects a revenge motive and is right but for the wrong reason. Gloria's senile father, ex-lock keeper Cyril, gets into an ongoing war with a mother and son on a barge holiday which ends in reconciliation when they save his life and he even teaches Peter a new piece of legislation.

Farmer Geraldine Merrick suspects vandalism when crop circles appear in her wheatfield. She plans to harvest immediately but widowed ufologist Terry is convinced it is the work of aliens and a site of scientific interest and requests Peter to stop her. Geraldine calms down when sci-fi fans pay to camp in her field but Peter suspects that Terry's neglected young son and Terry's rivals in the pub quiz know more than they claim. Lyle wins the day for an eccentric old couple whose sour-faced daughter feels they should be put in a home, thanks to an eccentric judge, but finds himself falling for rival solicitor Emily.

Widowed Nicky Laker, a doctor at a research lab which uses animal testing, asks Peter to defend her daughter Donna, who has vandalised the unit to expose it and lose her mother her job. In fact Donna's motive is not out of principle but fear of being cut out of her workaholic mother's life, whilst Nicky's work obsession is to find the cure to prevent Donna from dying of the hereditary illness that killed her father.The two are reconciled after Peter has acted as go-between. Lyle defeats a greedy developer out to evict a group of nuns - who are a hit in the local pub where they are temporarily housed - and Beatrice tells Alan the artist that he is not Petra's father, before getting a call from the man who probably is.

Grumpy but promiscuous judge Jeremy Harding is sent compromising photographs of himself with a young woman and blames Beatrice. She denies it before exposing him as the father of her daughter, Petra. Harding asks Peter to find the blackmailer, who turns out to be very close to home. Lyle is involved when Stan Geddick and his druids claim the local golf club is on the site of an ancient place of worship but he saves the day by proving that they are,geographically, way off course,so to speak. Stan rewards him by setting up an idyllic date with Emily,which is ruined when Lyle's mother turns up.

Lyle goes home to Stockport with his mother to prevent the council from selling off local allotments for a golf course. Lyle's younger twin brothers do not help the situation with their 'guerilla gardening' tactics but the discovery of a lady's slipper orchid growing in the allotments does. Peter acts for Andrew Risden who is refused permission by the headmistress to video his child prodigy cellist daughter Abigail's recital, on the basis it may attract paedophiles. Feeling under pressure, Abigail runs off but the head relents when she is eventually found. Beatrice helps Nigel pass his relationship counselling course via unusual methods and Sidney gets married, though not to Gloria. At the reception Peter suddenly collapses.

Peter is briefly admitted to hospital for tests and, on discharge, is engaged by David Morston, whose older brother Lord Robert, a mad ex-junkie, is selling off parts of the family estate and its titles when not cavorting nude in the fountain or shooting at people. Unusually, Beatrice, who was in rehab with Robert, helps resolve matters, showing that Robert's actions are, ultimately, for a good cause. Lyle suspects a local chemical firm of river pollution but he discovers that large corporations are not always in the wrong. Peter is diagnosed with diabetes, but blood tests show that he is not Beatrice's brother, in fact he is not Peter Kingdom at all, as Auntie Auriel confirms.
