Oscar Blaketon gets a major shock when he sees a man passing in a car. Blaketon is absolutely sure the man is Harry Bradshaw, who was one of the biggest villains in North Riding when Blaketon became sergeant at Ashfordly police station. The only trouble is that Bradshaw is dead and his death has been confirmed by two trusted police officers one of which is PC Ventress. PC Bradley is investigating a break-in at a renting cottage, but the only thing missing is the tenant John Baker. His body is later found in a quarry. He was murdered and it turns out he was an old accomplice of Bradshaw's. At the Woodside estates Geoff Atkins and his neighbour Syd Carter accuse each other of digging in each other's gardens at night. After his latest venture has gone badly wrong Vernon Scripps tries something completely new to him. He gets a regular job at a department store in Ashfordly. When the department store is closed down the old entrepreneur in him wakes up again.

Ralph Harrison gives his wife Penelope his late mother's diamond necklace as a wedding anniversary present and persuades .her to wear it to the fund raising disco at the Ashfordly Grammar School. During their absence their house is broken into, but only a set of teaspoons is taken. Sergeant Merton suspects that the thief was looking for something specific. He may be right because the following day the house is broken into again and the diamond necklace is taken. Gina is afraid of spiders. Vernon Scripps thinks that hypnosis may cure her and offers his services because he is an (instant) expert on hypnosis. When he is learning how to he accidentally hypnotizes David without noticing. Sergeant Merton continues to have dizzy spells and Dr. Summerbee finds out that he is diabetic. This may be bad for the good sergeant, but it most certainly causes warm feelings to develop between him and Dr. Summerbee's secretary Jenny.

Tommy Rawson breeds sheep dogs and he the favourite to win this year's trials as it has done two years previously with his dog Jess. His nearest competitor is George Harding, who is a close friend of Lord Ashfordly and used to have things his own way. When he cannot win fair and square he will stop at nothing to discredit Rawson and have his dog disqualified. Harding's wife Maureen is hardly any better. She has got severe anxiety and expects Dr. Summerbee to prescribe her pills for it at will. Vernon Scripps is providing lavatory facilities for the trials and he soon discovers that it involves more than just putting up a tent or two. Good news for Sergeant Merton. His diabetes will have no bearing on his position as sergeant at the Ashfordly police station as long as he gets his medication.

The bank has refused Richard Harvey a respite on his loan and will auction off his farm, but Harvey does not give up without a fight. It turns out to be a very mucky affair, literally, and that is just the beginning. Gina is smitten by Mark Jenkins, who hopes to make a good deal at the auction, but Oscar Blaketon has his doubts about him. Given Gina's previous experiences with men he is probably right. David makes horse radish sauce for Gina using his Auntie Beth's recipe. It is a very good sauce and Vernon Scripps thinks marketing it will turn a very good profit. He even promises David that he will have his name and picture on the labels.

Sergeant Merton gets a visit from his cousin singing star Deborah Vine. She likes Aidensfield so much she may even decide to settle down there. She is joined by her daughter Didi, an upcoming singer who has left her show because she is pregnant and does not want her father and manager Larry Prince to know. PC Bellamy spots the wanted criminal Scudamore while he is on patrol with PC Ventress. Scudamore is arrested, but manages to escape during transfer to Manchester. David gets a shock when he is supposed to unload Mr. Clough from his taxi and discovers that the old man has quietly passed away during the trip. Clough's daughter April needs a man (around her shop) after her father's death and takes an interest in David. Too much interest if you ask David.

Guy Foxton publishes and sells guide books. Unfortunately one of his guided tours crosses the private lands of Les Parnaby. When the police cannot do anything Parnaby decides to take care of the matter himself. It is not the first time Foxton has had a dispute about the right-of-way and PC Bradley kindly suggests that he removes the route from his guide and does not use it anymore, but Foxton is not forthcoming at all. David's and Vernon Scripps' lorry breaks down and PC Ventress gives Vernon a lift back to Aidensfield. On the way Vernon Scripps hits his head when Ventress has to avoid a sheep on the road. That bump changes his personality and makes him a kind, loving person. He even pays all his debts and gives David a two week holiday on his birthday.

Dirty Len Fairchild has died if of what seems to be tetanus, but turns out to be strychnine poisoning. Celia Beresford is in charge of the Ashfordly Rotary Club's annual old folks' outing to Whitby. She does not like that Vernon Scripps is away and David has to drive the old people and hijacks Oscar Blaketon to assist them. Shortly after she visits her father Fred Caldwell to "persuade" him to go on the outing her dog dies with the same symptoms as Dirty Len. It had been strolling on the Kirkby farm, where Len was a hired help. Sergeant Merton searches the Kirkby farm for the poison, but PC Ventress recalls another incident involving Fred Caldwell some years earlier. Caldwell claims he got rid of the strychnine then though. Then Celia's daughter Amanda gets ill on Caldwell's farm.

There has been a series of brand new tractor thefts in the area. They were all insured at the same company and stolen within days of delivery. Sergeant Merton reckons, Steve Calthrop will be the next victim and he tells his constables to watch Calthrop's tractor overnight. Calthrop sneaks out during the night to visit his mistress and while PC Bradley and PC Bellamy follow him his tractor is stolen. Vernon Scripps has a brand new idea. His latest venture is landscaping gardens beautiful enough to be the best of the village. The Naysmith-Jones's take advantage of his services, and since Vernon is not into the getting-your-hands-dirty part of the business as usual it is David's job to purchase the trees and plants for their garden - including a Greek statue that they want. He cannot afford the statue, but the garden centre salesman knows where he can get a cheap one second hand.

Cupid's little arrows hit everybody. Even Lord Ashfordly, who surprises everybody by introducing his new wife. On the first night in Aidensfield the newlyweds are held up by two masked and armed robbers. They especially seem to be targeting Lady Ashfordly, who is assaulted again the next day, and PC Bradley is assigned as her chauffeur and body guard. Joyce Jowett's sister has died and she needs Bernie Scripps' services as an undertaker. She is very demanding and as might be expected he cannot do well - or cheap - enough.

Gordon Purvis acts tactless towards Gina and Phil Bellamy tells him to finish his drink and go. Purvis does, but on his way out he hits Bellamy with his car and drives erratically. Unfortunately the charges against him are not sufficiently substantiated and Sergeant Merton lets him go with a warning. But Merton has another and more serious reason to let him go. Scotland Yard has Purvis under surveillance and has requested their assistance in this operation. PC Bradley is the best suited for the job, but he cannot tell anybody about it. The surveillance also includes horse trainer Kieron Doyle. Tricia Summerbee is smitten by Doyle's charm and takes him up on his offer to ride one of his horses. Thus the beautiful doctor unwittingly ends up in the middle of it all. Vernon Scripps gets a visit from his brother George, who he has never met. So he is very surprised to discover that George is actually a woman. He will also soon discover that she has a very expensive lifestyle.

The whole village and especially Mike Bradley mourn over the death of Dr. Summerbee. She is temporarily replaced by Dr. James Alway. Gina refuses to serve Bobbie Gray, because he is underage, but when he refuses to leave he gets into a fight with PC Bradley and PC Bellamy. The case ends in court, but Gray is acquitted by the presiding judge Charles Robertson. When Gray is arrested for a robbery he has committed Robertson confirms his alibi, because Bobbie Gray is actually his son. But it would have been healthier for Gray to stay in jail. On his way from Robertson's estate to the village he is the victim of a hit-and-run accident. Maggie Byrne turns up in the Aidensfield Arms and asks for her old friend Vernon Scripps. She is short of cash and asks Vernon to sell her engagement ring for her.

PC Bellamy set off in pursuit of a pursuit of a man, who supposedly stole the purse of Alice Armstrong. He does not catch the guy, but manages to retrieve the purse - minus her money. He is sure he will catch the culprit, but it may take some time because a series of break-ins at fashionable estates keep the police in Ashfordly occupied. The burglar may be a member of a small circus, which Vernon Scripps puts up for the winter. Scripps persuades Lord Ashfordly to let the exotic animals graze on his estate and open a wildlife park. But they may get more than they bargained for when the whole circus turns up and the animals escape and scatter all over Aidensfield. Col. Barber is very fond of telling stories about his exploits during the war, but his memory may not be what it used to be. Maybe it never was?

The Randalls were married in Aidensfield and they want their daughter to be wed at the same church. But Rev. Truscott is in dire need of bell ringers and asks Dr. Alway to help him out. The doctor enlists David and the Scripps's as his helpers, but bell ringing takes time to learn and not everybody in the village are that keen on the ringing of bells in and out of season. Lord Ashfordly is not satisfied with the income from his quarry. Therefore he hires Oscar Blaketon to keep an eye on the manager Mr. Briggs. Following an anonymous call the police discover that explosives are missing from the quarry. They also have to deal with the security in connection with the defence minister's visit to Fylingdales radar station. Oscar Blaketon has problems of his own. He has returned from a holiday in Spain with an accusation of violence hanging over his head.

Vernon Scripps and David are on their way in a tanker when they are forced off the road by an oncoming car. None of them get seriously hurt when the tanker overturns, but Vernon Scripps has a temporary loss of memory. Dr. Alway gets him admitted to his own hospital The Royal in Elsinby. The contents of the tanker ooze out on the ground and into a river and several people show signs of poisoning. Vernon Scripps is the only one, who knows what is in the tanker, and the hospital staff will not let anybody talk to him. Getting the tanker contents analyzed will take days and meanwhile nobody is allowed to use the tap water.

The vicar Harold Greaves grows marihuana in his greenhouse because it brings relief to his disabled wife Joyce. He takes on Jenny's brother Steve, who pays his sister a visit. But unlike his sister Steve is a nasty piece of work and when he finds out about the drug he does not hesitate to sell some of it to a group of mods from Whitby, who has been stirring up trouble in the village. When the vicar finds out Steve threatens to expose him if Greaves says anything or refuses to supply him. One of the mods, Kelley, takes a fancy to David and moves in with him and persuades him to become a mod himself.

There is a new bobby in Aidensfield. Steve Crane will replace PC Bradley, who has been transferred to CID. Crane is not the only newcomer in the village. Dr. Liz Merrick moves in at the surgery as the new GP in Aidensfield. She is concerned about the loss of patients since her predecessor died, but Vernon Scripps offers to deliver a letter from her to every potential patient in the village. Two neighbouring farms have been broken into, but the owners Jack Farrow and Walter Rawlins say the break-ins are mere trifles and not worth any police attention. PC Crane does not agree and suspects they cover something up. Gerald Dunphy is wanted for armed robbery and Mike's first case as a detective constable is to keep an eye on his girlfriend in case he shows up.

DC Bradley is tipped off by his informant Harry that Vic Hawking and Len Dowd have bribed the driver of a bullion van to make an unscheduled stop so that they can rob it of its shipment of gold. The police lay in wait for the robbers, but something goes wrong when the van stops at a different place than it was supposed to. Gina is not the only pretty face at the Aidensfield Arms anymore. Her niece Susie got in with a bad crowd and her mother wants her to get away for a while and stay with her aunt at the pub. But Susie is not that keen on getting away from anything and especially not from her boyfriend Jamie, who follows her to Aidensfield. He has escaped from custody and PC Crane gets more than his hands full keeping an eye on Susie in order to catch him. Dr. Merrick's waiting room needs redecorating and Vernon Scripps and his colleagues are more than happy to do it for her. Since Bernie is too busy the task goes to David.

Lesley Ford's father went missing in action during World War. A few days before her wedding to Barry Lee she finds a piece of a shot down Mosquito fighter on the moors. Following the visit to a fortune teller at an amusement park on her hen night she postpones the wedding until the plane's pilot has been found and given a proper burial. To save his upcoming marriage Barry tries to find the spot where the Mosquito hit the ground. But the crash site is considered a war grave and the Ministry of Defence do not take it lightly when someone messes around with war graves without authorization. and to top it off two more shady characters are caught lurking around the supposed crash site. A new, very officious bobby turns up out of nowhere in Aidensfield and Ashfordly But not even Sergeant Merton has heard of any new bobby being transferred to the area and the police must face the fact that the have a bogus bobby on their patch.

Dean and Alec Farley play Batman and Robin. They chase The Joker and his gang all over the village and one day they see how Lefty Bates and his pal Chuck break into a building at a farm, which has been empty for years. The new owner James Bexley does not want the police to snoop about and hires the caped crusaders to locate the burglars. But the police have more important things to keep them occupied. A gang of counterfeiters has been operating all over the north and some of their notes turn up in Aidensfield. Dr. Merrick is harassed by anonymous phone calls. At first she thinks it is her former boyfriend again, but it turns out to much more sinister than that. Vernon's Aunt Aggie is dead and the family has been invited to divide the inheritance. When he and David arrive only the house is left. The house and a seemingly worthless table.

Liz Merrick's former lover James Robson comes to Aidensfield to get her back. Before it comes to that he is killed by a single shot from a high powered rifle outside the Aidensfield Arms. But both DC Bradley and PC Bellamy were only yards away from him at the time, and one of them may have been the intended target. As if to prove the latter Bellamy is shot and wounded in the arm at the same spot the next evening. A likely suspect is Frank Clegghorn. He is a master marksman, has recently been dishonourably discharged from the army and dislikes the police just as much as his father Nathaniel does. Tim Barnet has had a break down with his classic Bentley limousine and checks in at the Aidensfield Arms while Bernie Scripps gets it repaired. He makes quite an impression on Gina and he finds her very attractive also.

Vernon Scripps has become a more or less permanent chauffeur for the unpopular business man Jim Pinder. Pinder even hires Vernon to haul a boat on a trailer for him. The lorries from Pinder's quarry are a nuisance to a lot of villagers in Aidensfield, but many of them also depend on the quarry to make a living. Things heat up when one of the lorries has braking trouble and almost hits some school children and protesters block the access to the quarry. Somebody has vandalized Lily Barton's boundary wall and two dozen sheep are missing. She is also ill and PC Crane asks Dr. Merrick to have a look at her.

Sergeant Merton thinks that the burglar poses as a potential buyer and breaks in later. PC Crane has been absent minded for a couple of days. He is expecting a visit from a woman. She is somewhat older than him and soon the village is booming with gossip. No blame on the villagers though. She failed to mention that she is his mother. A new guest, Lennie Beech, at the Aidensfield Arms flirts with Gina, but Oscar Blaketon does not trust him.

Vernon Scripps has really made a killing on the paintings he bought from Steve Crane's mother. He kept one of them though. The one called "Tower Bridge". He organizes an auction for the benefit of Sir Nigel Fethersone's charity foundation and is "persuaded" by Oscar Blaketon to donate the "Tower Bridge" painting himself. But somebody steals the painting and he gets David to make a duplicate. Jenny surprises an intruder at Sergeant Merton's house.
