It's not Christmas without an Agatha Christie whodunnit! Who's who in the fabulous Murder is Easy cast

Murder is Easy is a must-watch thriller this Christmas – it wouldn’t be the festive season without an Agatha Christie whodunnit – and the cast list is exquisite!

The story sees Luke Fitzwilliam heading to London when he happens across Miss Pinkerton, a woman who suspects a serial killer is operating in her home of Wychwood. She thinks she’s next on the list – and she’s not wrong!

When Miss Pinkerton is found dead, Fitzwilliam realises her suspicions were true. Now he must travel to the sleepy village of Wychwood to stop the murderer striking again.

Sounds intriguing, right? Here are all the faces to look out for in the Murder is Easy cast.

David Jonsson is Luke Fitzwilliam

British actor David Jonsson plays Luke Fitzwilliam, a Nigerian immigrant whose journey to London is interrupted by Miss Pinkerton. When she’s found dead, Fitzwilliam rushes to Wychwood to try to catch the killer.

To telly fans, David’s best known for his role as Gus Sackey in BBC Two drama Industry (2020 – present). Gus is a privileged young Oxford graduate starting work at London investment bank Pierpoint & Co. It’s a role that could not be more different to him – a shy young man who grew up in London’s docklands and was expelled from school. “I’m quite tame – a bit vanilla,” David told GQ. “I had to get advice from people on set about how to snort a line authentically.”

He also played MI6 agent Isaac Turner in season two of British spy thriller Deep State (2019).

Other roles include the lead in 2023 Hulu film Rye Lane, for which he received a British Independent Film Award nomination. He also had a small role in Endeavour in 2018.

David’s also had an impressive theatre career since he graduated from London’s Royal Academy of Dramatic Art in 2016. He made his West End debut in Mary Stuart in 2017, and later that year starred in Don Juan in Soho alongside David Tennant. In 2021, he won Best Actor at the Black British Theatre Awards for his role in and breathe… at the Almeida Theatre.

2022 saw David make Evening Standard list of Londoners to watch and receive an honorary mention from British GQ’s Men of the Year. Meanwhile in 2023, he was named a Tatler Bright Young Thing as well as a Screen International Star of Tomorrow. So many prominent publishers can’t be wrong – David is definitely one to watch!

Morfydd Clark is Bridget Conway

Welsh actress Morfydd Clark plays Bridget Conway, a social climber with a penchant for reading people. Her skill makes her the perfect fit to be Fitzwilliam’s crime-solving partner.

Fantasy fans will recognise Morfydd Clark for her starring role in Amazon Prime Video epic Lord of the Rings: The Rings of Power (2022). Sporting a long blonde wig and pointy elf ears, she played Galadriel – a role made famous by Cate Blanchett in the Peter Jackson trilogy films. Morfydd’s Galadriel was younger, more impulsive, and maybe the reason the plot of Lord of the Rings had to happen at all. She’s confirmed to return in the second series, which is slated for premiere in 2024.

The 33-year-old’s other TV roles include Mina in Mark Gatiss and Steven Moffat‘s 2020 recreation of Dracula. She also appeared as Sister Clara in season one of His Dark Materials in 2019.

Morfydd’s film work includes a BAFTA-nominated turn in psychological horror Saint Maud (2019). She also starred in The Personal History of David Copperfield (2019), The Man Who Invented Christmas (2017), Interlude in Prague (2017) and Love & Friendship (2016).

This year Morfydd appeared in rural horror Starve Acre, playing Juliette.

Penelope Wilton is Miss Pinkerton

Dame Penelope Wilton DBE portrays Miss Pinkerton, an elderly resident of Wychwood who does not believe recent local deaths were accidents. Rushing to Scotland Yard to report her suspicions, she comes across Luke Fitzwilliam.

Penelope, 77, is a huge name in acting across theatre, film, and TV. So much so that she was elevated to Dame for services to acting in Queen Elizabeth II‘s 2016 birthday honours. For her work in theatre, she’s won two Critics’ Circle awards, an Evening Standard award and – the big one – an Olivier. She’s had six Olivier Best Actress nods in total.

Most recently, she portrayed Anne, a wise old lady on a graveyard bench who offers advice to Ricky Gervais‘ Tony in the Netflix drama After Life. The show ran from 2019 to 2022, with Anne’s scenes being praised for some of the show’s most powerful.

Penelope also played Isobel Crawley in Downton Abbey (2010-2015), the mother of heir to the estate Matthew Crawley (Dan Stevens). Their arrival at Downton prompted the events of the drama. Penelope appeared in all six seasons of the drama, as well as two films.

A short but important TV role was that of Harriet Jones in Doctor Who. Penelope was introduced as the MP Harriet in 2005 during Russell T Davies‘ tenure, before progressing to uncompromising Prime Minister. Harriet later sacrificed herself for the good of humanity in 2008.

Other TV roles include Five Days (2007), Bob & Rose (2001), The Borrowers and The Return of the Borrowers (1992-1993), Jackanory (1984-1991), Ever Decreasing Circles (1984-1989) and The Norman Conquests (1977).

And he starred alongside James Nesbitt and Sarah Parish in medical drama Monroe (2011-2012).

Tom’s no stranger to Agatha Christie adaptations, either, appearing in Poirot (2008) and Marple (2007).

Elsewhere in 2023, he played Keith in the courtroom drama The Caine Mutiny Court-Martial.

Scottish actor Douglas Henshall plays Major Horton, a welcoming local who invites Fitzwilliam to a proper pub.

Douglas, 58, is another big name in TV. He’s recently best known as DI Jimmy Pérez, the face of BBC One’s BAFTA-winning crime drama Shetland (2013-2022). After 10 years in the role, Douglas handed the mantle over to Ashley Jensen in 2023.

Before he was Jimmy Pérez, he was Professor Nick Cutler in ITV sci-fi Primeval (2007-2009). The series received critical acclaim and became a cult hit.

Mathew Baynton is Dr Thomas

English actor Mathew Baynton plays Dr Thomas, a man of status in the Wychwood community. He does not enjoy Fitzwilliam shaking up the village status quo.

Mathew, 43, has a wonderfully quirky CV – excelling in writing, comedy and music as well as acting. He wrote and performed in five seasons of CBBC series Horrible Histories (2009-2013). Along with other members of the Horrible Histories cast, he formed the Them There comedy troupe. The troupe created and starred in Sky One sitcom Yonderland (2013-2016), plus the BBC’s Bill (2015).

Mark Bonnar is Reverend Humbleby

Scottish actor Mark Bonnar plays Reverend Humbleby, the local vicar. He’s concerned about the direction Lord Whitby is taking the village in.

Mark, 55, is yet another actor you’ll very much recognise from somewhere. First playing Bruno Jenkins in Casualty (2005-2006), he later landed a recurring role on The Bill in 2007. The BBC crime drama Paradox (2009) followed, alongside future Murder is Easy co-star Tamzin Outhwaite.

Another future Murder is Easy castmate, Douglas Henshall, was his co-star when he joined Shetland in 2013. He played Duncan Hunter until 2022, when both he and Douglas left the show.

He appeared in Line of Duty‘s second season (2014) as DCC Mike Dryden. Roles in Grantchester (2014), Midsomer Murders (2015), Vera (2015), Home Fires (2015), Jeckyll and Hyde (2015), Undercover (2016) and New Blood (2016) followed.

2017 saw Mark play major roles in BBC miniseries Apple Tree Yard and the second season of ITV’s Unforgotten. He began starring in Channel 4 comedy Catastrophe, a role he continued until 2019 when the show ended. He also starred in the revival of Porridge to mark the BBC’s Landmark Sitcom Season.

Next he starred in robot drama Humans (2018), then Summer of Rockets (2019) and Defending the Guilty (2019). He also played one of two brothers involved in a hit-and-run in Guilt (2019-2023).

She was also kidnapped by ex-lover Dan Sullivan (Craig Fairbrass). Her first run on the soap continued until 2006, before she returned again in early 2018. This time around, Mel was involved in a shoot-out and later died in a vehicle accident in 2019.

She also appeared in BBC One drama Red Cap (2003-2004), as well as in Hustle (2004).

Following her first stint on EastEnders, she starred in ITV’s The Fixer (2008). Next she appeared alongside future Murder is Easy co-star Mark Bonnar in Paradox (2009).

In 2013, she took over the lead role in New Tricks, portraying Detective Chief Inspector Sasha Miller. She played the role for two seasons before the show was ultimately cancelled.
