The production team, film crews and a cast with entourage camped up outside Thame museum on Friday to film part of the third episode. Now in its twelfth series, DCI Barnaby - played by actor John Nettles and his trusty sidekick DS Jones, played by Jason Hughes, continue to solve the mysteries surrounding weekly murders in Midsomer Mallow.

Filming for the show has entered its second decade and more than 132 suspicious deaths later, the production team have remained firm fans of Thame and the surrounding Oxfordshire and Buckinghamshire countryside.

Last Friday, the crew were working towards the completion of the third episode, which will result in a two-hour television slot and take 22 days to film.

Although crimebuster John Nettles was not on site, his colleagues Rosamaund Drury and Tom Rooke made an appearance.

They needed a museum for the current episode and Thame museum appeared to be the perfect location.

Bentley Productions is the team behind the series and head of productions, Ian Stracham, said: "Bentley productions chose Thame today as it has a museum that fits the Midsomer Murders look.

We are very grateful that the museum curator was able to accommodate us."

The crew stayed filming inside the museum all morning before moving to a location in a house in Thame in the afternoon.

The series is out next year.
