In addition to sorting out a feud between John and Steve, Henry answers a distress call from his culinary idol, the cantankerous Hilary Smallwood, who, in a moment of weakness, gave power of attorney to her nephew Colin. Not only has he sold her cottage and put her in a home but he is after the rewards to be had if he can publish her saucy memoirs, which she has entrusted to old flame, pig farmer Seymour Flint - who makes divine black pudding. Hilary is not long for this world but even from beyond the grave she can get one over on her greedy nephew.

As Henry mysteriously loses his sense of smell he is intrigued when Fisher seems obsessed with arresting tyre exporter Peter Watson and suspects that Fisher, about to divorce his wife, is having an affair with Mrs. Watson. In fact she has discovered that her husband is defrauding her charity and is using Fisher to trap him. Having seen the case through Henry, feeling used by Fisher to catch Watson, resigns from the police and immediately regains his sense of smell. With Gary turning down the offer of work at another kitchen, Henry and his staff and colleagues have every reason to drink to the continuing success of Pie in the Sky.

After a rave review by a hard to please food critic Pie in the Sky does a roaring trade. Henry, however, is at a boring police seminar where Fisher admits he is disillusioned by the job and considering quitting. Henry swaps their assessment papers, hoping it will aid his retirement chances but the trick backfires. A visit by another food critic ends in disaster and things go back to normal - to Henry's relief.

Fisher's 'research' project sends Henry and Sophia Cambridge to the nearby village of Wychwold, allegedly to assess public opinion of the police. However, Henry guesses - rightly - that this is Fisher's way of getting him to investigate the suspicious death of Dilip Patel, a philanthropist about to turn the ailing country club into a public leisure centre. Henry arrests the culprit and visits a culinary heroine whilst Steve solves a burglary from the restaurant.

Henry and the newly-promoted Detective Sergeant Cambridge investigate a Peeping Tom who steals ladies' undies and makes detailed obscene phone calls - all to women involved with restaurants, including Margaret. Henry suspects Hugh Downing, his handsome cheese supplier, but he turns out to have quite a different secret and ultimately it's Margaret who catches the culprit.

A customer is found dead in Pie in the Sky's toilet but when the emergency services arrive his corpse has gone. Henry traces his car and finds the boot full of paper money, after which the man's son comes to the restaurant, pursued by two detectives who claim that the family are notorious forgers and tell Henry that he is out of his league in dealing with them. Inevitably they must be taught a lesson in detection.

Armed robbers in crash helmets target the restaurant and customer Cherry Burdett's jewellery is stolen. Obnoxious D.S. Stringer investigates, alienating everyone with his insistence that it was an inside job and a staff member alerted the robbers to Cherry's booking. He accuses Gary because of his past, then Nicola - at whom he makes a pass - and her boyfriend Paul. When news of the robbery reaches the press Henry closes the restaurant to do his own investigation, solving the crime in time to mark two years of Gary giving up alcohol with a celebratory cake.

The man who wounded constable Ian Lefebvre and put him in a wheel-chair is being paroled, so Fisher, to keep Ian otherwise occupied, teams him with Henry in pursuit of the elderly Coverly sisters, mistresses of multiple cheque fraud and queens of cuisine who always leave their victims a delicious bread and butter pudding. Henry's task is three-fold, to give the embittered Ian his self-respect back, catch the ladies and, most important, obtain their wonderful recipe.

When Fisher allocates Henry to guard Sasha Wilkes, due to testify against her gangster husband, in the police 'safe house', D.C.I. Harding, who had expected the job, is resentful. Sasha is initially hostile but, won over by Henry's cooking, comes to confide in him. Harding uses a drug pusher called Vicky, who once knew Henderson, to discredit Henry and also discloses the safe house's location to Wilkes. Henry averts disaster and parts as friends with Sasha but wonders if they were used as bait by Fisher because he already suspected Harding.

Trout farmer Bill Pritchard's fiancee Jean goes missing after he has accepted a lucrative take-over by a chain fishery and pushy Inspector Browning accuses him of her murder, even before any body can be found. Bill's friends Henry and Margaret are not convinced despite Bill's confession that he may have killed her whilst drunk and set their own little trap to haul in the one that might otherwise have got away.
