For Midsomer’s 100th episode, first shown in 2014, the makers joined forces with the producers of Scandi hit The Killing to take the show abroad for the first time.

When the boss of a local biscuit company is found dead in Copenhagen, DCI John Barnaby and DS Charlie Nelson head to Denmark and team up with local cops played by The Killing’s Ann Eleonora Jørgensen and Borgen’s Birgitte Hjort Sørensen.

Sanjeev Bhaskar and No Offence’s Joanna Scanlan are among familiar Brit faces.
