Henry supplies the catering at his friend Alistair's pheasant shoot, where Fisher is among the guests. Another member of the party is shot and killed and it looks as if Fisher accidentally shot him but Henry's investigation reveals a crime of passion involving a love triangle, a jealous husband - and a cover-up.

Henry has to solve a series of thefts from lorries and gets unexpected help from private security firm Troubleshooters. Their accuracy is such that he is suspicious of how they came to know of the crimes and believes that there is a possible informer within police ranks feeding them information for a reward. Troubleshooters are due to play the police eleven in an important football match. Both teams boast an ex-professional, in the police team's case Kirk Flowerbridge, who has a murky past and a liking for the drink. Fisher tasks Henry with minding Kirk and keeping him sober for the match. In the process of helping Kirk,Henry gets to identify the informer.

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.
