James Herriot, MRCVS, a newly qualified vet, arrives at Skeldale House for a job interview. It is the mid-1930s, and work is hard to come by. While James waits for Siegfried Farnon, his potential employer, he meets Mr Biggins for the first time. James has to earn his money even before securing employment. Siegfried takes James to see Mr White's lame horse and lets him both evaluate and treat it, before they venture on to Barrow Hills to see Bert Sharpe's cow, Violet, which makes its mark on James. After meeting a few locals in the pub, James is hired. James treats Phineas Calvert's cow, which has developed sunstroke, and decides - under the watch of the difficult Mr Soames - to euthanise Lord Hulton's valuable horse after he diagnoses that it is too far gone with an agonising torsion.

Characters: Mrs Hall, Bert Sharpe, Diana Brompton, Mr Biggins, Mr White, Ted (barman), Soames, Phineas Calvert, Mrs Calvert.

Tristan Farnon does not appear

Siegfried settles James' nerves by confirming that he acted correctly with Lord Hulton's horse. James picks up Siegfried's brother Tristan from the station upon his return from veterinary college in Edinburgh, having failed pathology and parasitology. At first Siegfried sacks Tristan, but then decides to put him to work by collecting payments on market day. He misplaces the receipt book, however. James has his first encounter with Mrs Pumphrey and her pampered Pekingese pet dog, Tricki-Woo, who has developed "flop-bot". He calls again a few days later when another ailment is reported — this time "crackerdog". James visits Mr Dean and his 13-year-old dog, Bob, which has developed a cancerous growth in his abdomen. James decides it is best to put the animal down. Dean later gets a puppy and names it after his recent departure. Tristan plays a phone prank on James, pretending to be farmer Sims, of Beal Close. James exacts revenge by calling Tristan, pretending to be the farmer whose calf bed the duo put back in earlier in the day, saying the same thing has happened again.

Characters: Arthur Handshaw, Tommy, Reynolds, Smedley, Hodgekin, Mrs Pumphrey, Mrs Hall, Mr Dean, Soames, Diana Brompton.

Helen Alderson does not appear

With paperwork becoming out of hand, Siegfried decides to employ a secretary, a Miss Winifred Harbottle. The result is not quite what he intended. On a call to her father's Heston Grange farm in Ellsdale to treat a calf with a fractured leg, James meets Helen Alderson for the first time since they were on the bus together. Miss Harbottle arrives. She is immediately put out by the slipshod administrative set-up at Skeldale House. She puts in place a change in their working methods, starting at 9.00 AM sharp the following morning. Miss Harbottle gets Mrs Hall's back up early on in their relationship by asking her not to touch any of her paperwork while she undertakes her duties. James coaxes Mrs Pumphrey into letting the vets look after Tricki-Woo at the surgery for a week so that they can give him the care he needs. Mrs Pumphrey finds it difficult to cope with the thought, while Hodgekin is beside himself with joy. Miss Harbottle starts to inflict her professionalism on the vets. Siegfried retaliates by regularly emptying out the petty cash box. Mrs Pumphrey sends James an expensive and elaborate gift basket. She also holds a "welcome home" party for Tricki-Woo. James attends an early-morning call and on his way back, and still in his pyjamas, he stops in to check on the Aldersons' calf. Siegfried takes Miss Harbottle to task about the fact that the cash box was empty when Siegfried needed to give change to two clients. Also, it is the tenth of the month and still the accounts have not gone out. The secretary storms out.

Characters: Mrs Hall, Miss Harbottle, Mrs Pumphrey, Hodgekin, Francois (Mrs Pumphrey's butler), Dixon.

Tristan uncovers James' interest in Helen when mentioning he saw her in Richard Edmundson's Bentley. James is called out late to Dan Cooper's cow, which is stuck in a bog. Tristan, meanwhile, stays out all night drinking with the bell ringers. In an attempt to sneak in, he is caught by Siegfried, who comes to the conclusion that his little brother has too much time to spare; as such, since Siegfried thinks he is "fast becoming a drunken, idle shirker," he puts Tristan in charge of his new piglets. James checks up on Tricki-Woo, who has a clean bill of health for once. Mrs Pumphrey reveals her new arrival: Nugent, a piglet. Siegfried reaches breaking point with Miss Harbottle. She presents him with paperwork to look over, which, much to her distress, he decides to tear up and throw the pieces over her head. At breakfast, Tristan reads out a piece of mail he has received: a letter of resignation from Miss Harbottle. Siegfried cannot contain his excitement. Albert Crump calls the surgery about his mare, which has Monday morning disease. Tristan dispatches James, but not before he lets on that he's been putting out delicate inquiries about Helen. She is, he reveals, a member of the Darrowby Music Society and every Tuesday attends their evenings in the village hall. He suggests James signs up too. At Mr Crump's, James samples some of his homemade wine. He gets sloshed, but then has to drop in on the teetotal Bamfords, who live at nearby Holly Bush Farm. James attends his first Music Society meeting and makes a point of assisting Helen with the washing up. He asks Helen out on a date on Saturday, and she accepts.

Characters: Charlie Dent, Felicity (uncredited), Dan Cooper, Mrs Hall, Miss Harbottle, Mrs Seaton, Mrs Pumphrey, Richard Edmundson, Albert Crump, Mrs Crump.

Driving along the moor tops, James comes across a black Labrador stuck in the mud. He rescues it and decides to take it to Sister Louisa Rose to see if she can find it a home. James does not seem to be getting anywhere in his pursuit of Helen. Tristan convinces him take her to the ritzy Reniston hotel for dinner, but the date does not go well. To compound matters, Tristan suggests that he try seeing a different girl. He arranges a double date at a dance, with local girls Connie and Brenda, but things take a turn for the worse when Helen shows up with Richard Edmundson. James and Siegfried treat a pony of gypsy family the Myatts.

Characters: Mrs Hall, Sister Louisa Rose, Mr Plenderleith, Mrs Plenderleith, Connie, Brenda, Jess Myatt, Mr Worley (barman), Richard Edmundson.

The two pieces of gypsy music that are heard during James' visit to the Myatts are "Ditchling Beacon" and "English Pasture", by John Leach, part of a KPM series.

Siegfried is under the cloud of a cold, leaving James to carry the burden of the visits. Helen brings her Border Collie, Dan, to the surgery. James is embarrassed by his performance when he saw her at the dance, but he finally manages to make a date with her. They go to the Darrowby Plaza with the intention of seeing a film about the Hebrides but it is changed without notice to a Western, Arizona Guns. James visits Isaac Cranford, who tries to coax James into fraudulently reporting that the farmer's cow died from a lightning strike instead of acute heart failure. Tristan decides to bring the legend of the Raynes Abbey ghost to life. It is Siegfried's turn to visit Cranford, this time to treat his boar. Before he leaves, Siegfried reminds Cranford about the state of his account. James gets a lift back to Darrowby from P.C. Blenkiron. En route, they see the "ghost" and promptly give chase. Back at Skeldale House, Tristan is forced to reveal himself. Tristan is asked to post a faeces sample to the laboratory and a bottle of ointment to Cranford. He mixes them up, which results in Cranford smearing an undesirable product into his boar's skin. To Siegfried's obvious glee, the mistake results in Cranford terminating their services.

Characters: Isaac Cranford, Mrs Hall, Jeff Mallock, Mrs Dalby, Billy Dalby, William Dalby, Joe Kendall, Horace Dawson, P.C. Blenkiron, Gobber Newhouse, Arthur Handshaw, Charlie.

James drives by the funeral of Billy Dalby. After informing Siegfried of the news, he visits Mrs Dalby to pay his respect. The hard-of-hearing Joe Mulligan brings his "womiting" dog, Clancy, into the surgery. James is finally beginning to make real progress with Helen, who invites him to Sunday tea at the Aldersons', but ends up treating one of their cows that falls ill. The cow dies before James' treatment has a chance to work. After Siegfried buys a new Rover, James inherits his old one. When Tristan was up on a fell drinking Theakston's Nutty Brown Ale with James, he accidentally releases the handbrake. The pair watch as the car careens into the new shelter on the golf course. It is an incident that Siegfried just happens to read about in the morning paper. The duo's silence speaks volumes. Tristan blames the broken headlamp on an accident with a farm gate. With his car in being fixed, and James' brakes not up to standard, Tristan asks Siegfried if he can borrow his Rover to get to a call in Sorton. Tristan, of course, crashes it into a wall after swerving to avoid a flock of sheep in the road and has to break the news to his brother.

Characters: Mr Alderson, Mrs Dalby, Gobber Newhouse, Mr Worley, Richard Edmundson, Joe Mulligan, P.C. Smith, Charlie, Aunt Lucy, Daphne, Lenny Butterfield, William Dalby.

Tristan and Siegfried have to treat Mr Mulligan's giant dog, Clancy. However, they are all somewhat concerned over the sheer size of the animal. Siegfried, Tristan and Mrs Hall all give James some advice regarding Helen. James takes her to Bolton Castle, where he proposes to her. She accepts, and then James has to face the task of asking Mr Alderson for his permission to marry his daughter. Egged on by Tristan, Mr Biggins entertains the regulars at the Drovers. Mrs Dalby is worried about her cattle, and James struggles to find a diagnosis until he realises that the cows have rings around their eyes, as if they are wearing spectacles.

Characters: Mrs Hall, Joe Mulligan, Mr Alderson, Mrs Dalby, Mr Biggins, Charlie, Bert, Aunt Lucy, Richard Edmundson.

Siegfried is invited to the Brawton races. He knows the circuit is looking for a new vet, but his chances fade after meeting up with fellow vet Stewie Brannan whom he has not seen for several years. The Ministry of Agriculture requires the practice to undertake tuberculin testing the same week that James and Helen are on their honeymoon. James proposes a solution. James and Helen are married.

Characters: Mrs Hall, Pickersgill, Olive Pickersgill, Sidlow, Stewie Brannan, Major General Ransom, Mrs Ransom, Colonel Tremayne, Mrs Tremayne, Head Lad.

James and Helen are on a working honeymoon, carrying out tuberculin testing. They are staying at Carperby's Wheatsheaf, an inn with an overly-doting landlady. Siegfried decides that it is time Tristan did some serious work for his examinations. James meets local vet Angus Grier and his student, Clinton. He invites James along on a call and provides him with a peculiar change of clothes. Siegfried hires student Richard Carmody while Tristan is away for exams.

Characters: Mrs Hall, Angus Grier, Mrs Burns, Mrs Allen, Mr Allen, Clinton, Mrs Grier, Adderley, Tolly, Richard Carmody, Earnshaw, Smith.

A local smallholder, Frank Metcalfe, has spent all of his savings on new livestock. When the animals become seriously ill with brucellosis, the vets have their work cut out trying to save the day. Tristan returns from veterinary school in Edinburgh and confides in James that his exams may not have gone all that well. Tristan takes a dislike to Carmody and convinces James to let him see what real work feels like. The vets and the village doctor, who has set up practice next door to Skeldale, see an opportunity to teach Gobber Newhouse, a locally bully and wife-beater, a lesson when he steps on a rusty nail.

Characters: Richard Carmody, Mrs Hall, Frank Metcalfe, Mary Metcalfe, Harry (Dr.) Allinson, Gobber Newhouse, Mrs Tilson, Mr Dent, Eli Bagley.

Tristan receives confirmation that he has failed his exams again. To butter Siegfried up, he begins a strict tee-total, smoke-free, healthy lifestyle, but confides the truth in James. James has to deal with Mrs Donovan, a self-educated animal healer whose dog is killed in an accident, and with Angus Grier, who has a broken arm. When Siegfried brings everyone together in the Skeldale living room to toast Tristan and his new way of life, Tristan has to come clean. It leaves Siegfried in a fit of rage.

Characters: Mrs Hall, Angus Grier, Mrs Donovan, Mrs Mallard, Mr Bantock, Inspector Halliday, Nathaniel Adamson, Mrs Grier, Arthur Handshaw, Sam Broadbent, Connie, Betty.

Foot-and-mouth disease strikes in the Dales. As a precaution, Siegfried confines himself to Skeldale House. Dealing with a very sick animal, James administers a large dose of anaesthetic. He expects the animal to quietly pass away, but is amazed to find that it makes a complete recovery. He repeats the treatment with Mrs Flaxton's pet poodle.

Characters: Mrs Hall, Dowson, Bob Rigby, Kitson, Mrs Flaxton, Skipton, Betty.

The practice is going through a very busy time. It is raining cats and dogs - literally! - when James comes face to face with Mrs Bond's cat, Boris, which James describes as a miniature puma. After initially scoffing at their colleague's story, the Farnons experience it for themselves. James agrees to care for Mr Dean's dog after he passes away. He also treats a farmer's newly acquired bull calf, but struggles to come up with a diagnosis and appropriate treatment. Siegfried wants James and Helen to move out of their cramped living quarters and into the suite at the top of the house. He is also growing tired of his brother's aptitude of pretending to look busy.

Characters: Mrs Hall, Mr Bond, Mrs Bond, Harry Sumner, Mr Dean, Joe Mulligan.

"In 'Cats and Dogs', Sonia Graham, who played Mrs Bond, had a wild cat up a tree; that was good stuff, I remember that vividly," recalled Robert Hardy in 2016. "I decided to sing an old song which I knew as I approached this cat, of whom Siegfried was terrified. I was singing this old country song under my breath: 'Oh what have you got for dinner Mrs Bond? There are geese in the orchard and ducks on the pond...' I remember it worked wonderfully well. Sonia was thrilled with that. It was just a lucky chance that her character was called Mrs Bond! And I remember that lovely location we were at. It was an old abbey. We went there again for another do with Mrs Bond — two or three times, I think."^[1]

It is lambing time again in the Yorkshire Dales. Siegfried and Tristan treat Mr Benson's flock of sheep, several of which are suffering from a severe calcium deficiency. Others have become victims of a dog. Siegfried has to make a late-night call to Harold Ingledew, who is less than helpful after an evening of drinking at home. Much to Siegfried's chagrin, he repetitively sings "(You're My Heart's Desire, I Love You) Nellie Dean" and "Lily of Laguna". James is still confined to the surgery because of a sore ankle. He meets loner Roderick Perowne, a hatter who can't abide much. His dog, Sligo, has been injured, and Peter Marston, whose dog, Jack, appears to have been caught up in some wrongdoings.

Characters: Mr Benson, Mrs Hall, Roderick Perowne, Peter Marston, Mrs Marston, Harold Ingledew.

The musical piece "Over the Hedgerows", by Johnny Pearson, is featured during the lambing sequence.

Tristan is faced with a lawsuit after treating Albert Skerry's bloated cow at the same time as Mr Skerry lights a match. Ewan Ross, a vet in nearby Scarburn, asks Siegfried for some help. Siegfried suggests James gives him a hand. Ross turns out to be a formidable character whose expertise in horses is tempered by his fondness of alcohol. Siegfried buys a flock of guinea fowl and charges Tristan with keeping them. After feeding them, however, someone forgets to close the gate.

Characters: Mrs Hall, Ewan Ross, Virginia Ross, Marmaduke Skelton, Cornelius Skelton, Albert Skerry, Jess Hopgood, Tommy Thwaite, Colonel D'Arcy, Sammy Stubbs, Mr Sykes.

Helen, James, Tristan and Siegfried have lunch at a swank French restaurant, where Tristan meets Julia Taverner. Taken by her, he gets a chance to woo her when James is called out to treat her father's dog. Mrs Pumphrey visits the surgery and passes on some advice to Tristan in his pursuit of the object of his affection. James has to contend with the Bellerby family, of Haldon. He offers to give them a lift back to Darrowby to attend a performance of Handel's Messiah at the church, but the family's lunch appears interminable. James also has to treat Tim Alton's prize pig who has gone off her feed, the Taverners' dog, Dilly, and he faces a dilemma when Mrs Tompkins' budgerigar dies in his care.

Characters: Mrs Hall, Dick Taverner, Beatrice Taverner, Julia Taverner, Mrs Pumphrey, Miss Stubbs, Mr Bellerby, Mrs Bellerby, Ruth Bellerby, Bob Bellerby, Tim Alton, Jennie Alton, Mrs Tompkins, Jacques, Mrs Broadwith, Jack Almond, Arthur Handshaw, George, Tom.

He brings it to his next client, Mrs Butler, who names the kitten Moses and says she'll look after him. James and Tristan visit Mr Wilkinson's White Cross Farm to look at his "colt" Dancer, which turns out to be a six-year-old stallion. James meets Granville Bennett and ends up feeling the worse for wear. Siegfried has to follow up with Dancer, and is on the receiving end of the stallion's anger. Siegfried sets about collecting some outstanding debts, with his crosshair set firmly on Dennis Pratt.

Characters: Mrs Hall, Granville Bennett, Dennis Pratt, Mrs Barker, Zoe Bennett, Mrs Butler, Mr Wilkinson, Mr Wellerby, Mr Dawson, Charlie Ormonroyd, Boy, First Nurse, Second Nurse, Fred.

Helen Herriot does not appear

James uses a hormone treatment on Roland Partridge's dog, Percy, with interesting results.

The annual cricket match between Rainby and Hedwick is a fixture that Siegfried and Tristan have learned to avoid. This year, it is James who gets conned into playing.

Characters: Mrs Hall, Mrs Pumphrey, Mr Gilling, Jess Myatt, Mr Hewison, Mrs Hewison, Mr Mallock. Uncredited: Margie Myatt.

During the closing credits, footage is shown of the empty Skeldale kitchen; Christmas presents under the tree in the dining room; and Mrs Pumphrey hanging a stocking of toys on Tricki-Woo's bed.

James deals with tuberculin testing. He is summoned to the Min of Ag by Charles Harcourt when the test results cause confusion. Siegfried has to deal with Murray, a dog owner who only believes in the strictest of discipline for his charge. He also has to deal with dying sheep on the grouse moors, a result of louping ill. Helen gets a job as a secretary, but James is not sure he approves. Siegfried, meanwhile, thinks it is a wonderful idea; Tristan less so, when he realises he will have to pick up the administrative slack in the partnership. Mrs Hall tells Siegfried she has to leave to help her brother, who is now working his farm alone.

Tristan and Siegfried meet a tramp named Roddy Travers and his dog who are passing through the area. Mrs Hall has gone to Brawton to visit her sister, Dorothy, whose husband is sick and has been told he cannot return to work. Tristan reluctantly agrees to take over the household chores and duties in her absence. Siegfried is less than sympathetic when his brother starts to complain.

Characters: Mrs Hall, Mr Mount, Mr Scargill, Deborah Mount, Wesley Binks, Mrs Binks, Mr Jenkins, Mr Weeting, Brian Weeting, Dennis Weeting.

"Robert Hardy did such lovely things with his performance," remembered Paul Clayton, who played Brian Weeting. "I can remember him giving us that look after we tell him that we are off to war. He had a line, but he chose not to say anything. He just paused. What I learned from him was he always used this pause, which gave his scenes breathing space, which in turn gave the editors choice on which character is telling the story at that moment."^[1]

"In 'If Wishes Were Horses' I had to make it look like that car was driving itself, which was quite a difficult thing to do, driving down the hill, looking at the rooftops of the houses," recalled Peter Davison. "That was a good gag — as was the Health and Efficiency gag. I used to love that one. From my childhood it was like, 'Wow... nudists!' So when one turned up on the set in an earlier episode, I thought, 'I've got to have Tristan reading this.' I liked putting in the gags; I just loved the idea that he was smoking fags in the surgery next to a 'No Smoking' sign. I put in one great gag where I put the cigarette in the desk and I shut the drawer and then smoke started coming out! I just had fun with that aspect of him, and this character gave me licence to do all those things. We all had great confidence by this point and we just loved doing it."^[1]

It is James and Helen's anniversary and he's planning a special celebration. The evening, at the highbrow Harlequin restaurant in Bickershaw, is nearly ruined when a goat eats his cheque book. Siegfried starts dating Margery Egerton. Tristan, meanwhile, thwarted in his attempts to see Deborah Mount, turns his attention to previous conquests. James has to pay several visits to Mr Bailes, whose dog has an affinity for scaring the wits out of visitors. Mrs Hall over-imbibes at the Women's Union sherry party.

Characters: Mrs Hall, Mrs Egerton, Mr Bailes, Mrs Ainsworth, Mr Biggins.

War is becoming a distinct possibility, so Helen stocks up on food, while Tristan, at the request of his brother, puts tape on the windows in an attempt to minimise the chance of them shattering if the bombs arrive. Siegfried decides that Skeldale House should conserve its food supply by having its occupants eat together. Mrs Hall takes his instructions to economise a bit too seriously. James treats Miss Westerman's dog, Hamish. During the dog's recovery, however, Tristan manages to lose it. Siegfried tries to pair his brother up with the dour Deirdre Headingley, but he manages to wriggle his way out of it. The vets forego a soiree with the Headingleys in order to treat a stray dog that has been in an accident.

Characters: Mrs Hall, P.C. Blenkiron, Miss Westerman, Mr Stokill, Major Headingley, Deirdre Headingley, Lydia.

James and Siegfried get to see a modern milking parlour when they attend a calving. There are problems when the milkman's horse has to be taken off the road for treatment. Miss Westerman returns with Hamish. Tristan tries to avoid her, given that he misplaced the dog last time he was put in his care. She is concerned about the rumours that dogs will need to be euthanised in the event of war, but Tristan puts her mind at ease. The vets agree to spay a cat for a minimum fee, thanks to Tristan, but find they may have been taken advantage of. Siegfried treats Herbie Hinchcliffe's aging horse, Dolly, and becomes emotionally involved in the case when it comes to putting her down.

Characters: Mrs Hall, Herbie Hinchcliffe, Mr Blackburn, Mrs Beck, Miss Westerman, Mrs Bravington.

"In 'A Dying Breed' we corpsed a lot," remembered Carol Drinkwater. "We laughed out loud when Peter had to come into the breakfast room and tell us all that a horse had to be put down. Every time Peter came in from the telephone to say, 'He's had Dolly put down' we all burst out laughing. I don't know why. It must have been something to do with the way Peter delivered the line the first time and we all laughed, and Peter went, 'What?' The director asked why we were laughing and we couldn't say because we didn't know. Any time we tried to do this scene, we burst out laughing every time Peter came into the room, even before he talked about this sick animal."^[1]

After his recent experience with Dolly, Siegfried has become somewhat shy around horses. James has to deal with the unfriendly Ralph Beamish, an arrogant horse owner who continually ignores his advice. The vets have to deal with an outbreak of Foot and Mouth Disease on Duggleby's farm. War is declared.

Characters: Mrs Hall, Ralph Beamish, Duggleby, Mrs Beck, Mrs Bailey, Mr Bailey.

"When you think we made ninety episodes, I have very few actual recollections of scenes that I played," recalled Robert Hardy. "Though one of my favourite ones — because it was so true, I think — was my scene with Peter when war is declared, and we were sat at the top of a ridge, looking around at this wonderful Yorkshire countryside."^[1]

Assistant floor manager David Tilley remembered: "The racing stables featured in "Brink of Disaster" were at Middleham, where Jumbo Wilkinson was the trainer. I remember them being pleased with their young apprenticed rider who had won his first race the day before we filmed. Because there was so much filming for this episode and "Matters of Life and Death", the studio recordings for both episodes was combined into the same two-day slot at Pebble Mill."^[1]

With Mrs Hall away visiting a cousin, Tristan tries his hand at doing the cooking again. Siegfried, however, wishes he had not bothered. James fills in for Stewie Brannan while he's on holiday. He and Helen visit the dog track when he has to act as Duty Vet. The vets have to deal with a dog that has been hit by a car.

Characters: Mrs Hall, Mrs Holroyd, Peter Gillard, Marjorie Gillard, Mr Pymm, Mr Coker, Horace.

There is an outbreak of unexplained dog poisonings in the Darrowby area. Siegfried decides to investigate. Tristan has a farewell evening out with the local bell ringers. James and Tristan go to the bell tower. As can be expected, things do not go smoothly. Siegfried treats Joan Clifford's dog, Saxon, but the case has specific implications for her. James, meanwhile, treats the inexplicably-loud Len Hamson's pigs.

Characters: Mrs Hall, Joan Clifford, Rob Benson, Len Hamson, Elijah Hamson, Nathaniel Adamson, Bert Bartle, George.

Helen Herriot does not appear

James visits Lord Hulton's stately home. Hulton has taken a liking to a horse that has wandered onto his property from the nearby military barracks. At the Billings' farm, James finds young calves who are emaciated. He thinks they have ingested an irritant of some kind, but the vets cannot isolate the source. Mrs Hall selects one of Siegfried's finest wines — a 1928 Oublion — for the Herriots to enjoy on their evening alone. Siegfried begrudgingly agrees to the pairing, even though it means he's missing out on one of Mrs Hall's steak and kidney puddings. James fails to save a dog belonging to Paul Cotterell.

Sandy Byrne, wife of writer Johnny: "I'll tell you a funny story about Mr Sowden's farm in "Will to Live". The location was picked because it was filthy and the real farmer was delighted they were going to film on his farm, but when the unit arrived, he had scrubbed it spotless, so the crew had to pump all this shit back into make it filthy again. I remember Christopher Timothy stood on the side of a hill with a plastic rain hat on, because they needed to keep his hair dry for continuity."^[1]

"The last episode of the third series, while maybe less amusing than others, contained some of my favourite scenes," recalled Peter Davison. "The final shot was James driving away from Darrowby, and the first two people he waves to are Olive and Charles Turner, the owners of Cringley (Skeldale) House, which they had recently sold to be turned into an old people's home."

The only known outtake released from the series occurred when Siegfried gets up from the living room desk to answer the phone call from Simon Tanner. Peter Davison bursts through the door in a superhero outfit and exclaims, "Bill Sellars on the phone, Siegfried. Wondering if we'll do a fourth series?" Christopher Timothy drops down onto the armchair behind the door and adds, "Holy television producer, Siegfried! What should we do?" "Well, look here, superchaps, I'll tell you what. Fourth series, eh? I'll talk to him on the phone and while I'm doing that, you attack from behind," concludes Robert Hardy.^[2]

The war finally over, James returns to Darrowby to rejoin his partners in veterinary practice. He is having trouble readjusting to civilian life, however. His first call, of course, is to Mr Biggins, who has not changed and does nothing but complain. Relations are also strained with Helen: James is short-tempered and cannot open up to her. A new housekeeper, Mrs Hubbard, is hired to replace the late Mrs Hall. Her culinary skills prove to be severely lacking compared to her predecessor's.
