Why it matters
The programme marks case 100 by taking Barnaby abroad without abandoning a properly tangled Midsomer family business.
Calder's Biscuits chairman Eric Calder is murdered during a trip to Copenhagen after eating biscuits poisoned with strychnine. Because the package was sent from Badger's Drift, Barnaby and Nelson join Danish detectives Birgitte Poulsen and Anna Degn to trace a case that moves between the Calder factory and Copenhagen.
The investigation reaches into the company's ownership, a valuable family recipe and connections formed long before the present business trip. The two police teams compare evidence across countries while the Calder family and its associates offer carefully edited accounts of who profited from the brand's success.

Break a second seal: reveal the verified killer
Who was the killer in The Killings of Copenhagen? (spoiler)
Clara TroutClara poisoned Eric Calder, killed Julian Calder and stabbed Ernest and Atticus Bradley after learning how the Calder business had taken credit for her mother Agnes's recipe. Her attempted killing of Armand Stone in the factory ovens was stopped; Agnes's earlier death after a long illness remains separate.
Verified motive
Clara wanted public recognition and retribution for her mother Agnes, whose Golden Clusters recipe had been taken while others received the acclaim. She killed the Calders and targeted Armand as beneficiaries of that theft, then killed the Bradleys because they treated Agnes's legacy as something they could sell back to her for money.
Verified decisive clue
Archive case 100 · checked 25 September 2026The torn recipe pages in Eric Calder's keepsake bookThe missing pages point to Agnes Trout's original Golden Clusters recipe and the deal that transferred credit to the Calder business. That connection exposes Clara's grievance and links the Calder and Bradley killings to her campaign for her mother's recognition, while Agnes's death and Armand's interrupted oven attack remain distinct.
