A new Agatha Christie programme filmed partly at Sorn Castle is set to air on the BBC tonight (December 27).

Murder Is Easy, set in 1954, is a two-part adaptation of the mystery thriller by the 'Queen of Crime', that was first published in 1939.

It follows the story of Luke Fitzwilliam as he arrives in the UK from Nigeria for a job in Whitehall.

The luxury wedding venue was selected as one of the ideal locations for filming a section of the thriller.

Mark Bonnar, who plays Reverend Humbleby in the episodes, said that Sorn Castle was an "amazing" place, as he found himself wandering around.

Speaking to the BBC for the release, he said: "One key location was Sorn Castle, which is a 19th century castle.

"It is an amazing place, and as all actors do - which is why you should never leave us alone - I loved wandering into rooms we were not supposed to wander into when we're on location.

"So please, if you ever think it's a good idea to let a film crew into your house, know that the actors will be snooping around in your drawers.

"It’s an incredible building – beautiful, with the architecture and the history that's there."

The first episode of Agatha Christie's Murder Is Easy will air on BBC One on Wednesday, December 27 at 9pm, with the second and final episode at the same time on Thursday, December 28.

Both episodes will be available on the iPlayer after broadcast.
