Dublin Murders: Meet the cast and characters of the BBC One thriller

Killian Scott and Sarah Greene star in the supernatural crime drama, which is going to have you hooked this autumn.

BBC One has been knocking it out of the park with dramas this autumn. Peaky Blinders, World on Fire and The Capture have been among the best series of 2019.

But Dublin Murders – which airs on Mondays and Tuesdays at 9pm – is probably the best of the lot. Written by Sarah Phelps and based on the Tana French Dublin Murder Squad novels, this is a detective show unlike any other you’ll see this year.

An unmissable psychological and emotional thriller, this eight-episode drama is not to be missed.

Meet the cast and characters of Dublin Murders on BBC One.

Killian Scott – Plays Detective Rob Reilly

Rob is the one English character – although he is played by Irish actor Killian – who has come to Dublin to be part of the murder team with Detective Cassie Maddox.

"In the process of investigating this murder over the course of eight episodes, we see Rob and Cassie’s lives begin to self-destruct," said Killian.

"By virtue of this particular case both he and his partner Cassie begin to unravel, in the sense that a lot of regular boundaries are crossed, both personally and professionally. We also see how far people go to get what they perceive to be the truth. I would say that’s where Rob’s real fixation lies: it’s in the truth, which he pursues ruthlessly."

Who is Killian Scott?

Killian starred in the award-winning crime drama Love/Hate, the BBC dramas Strike and Ripper Street and the films Calvary, 71 and The Commuter.

Sarah Greene – Plays Detective Cassie Maddox

Rob’s partner is "quite a young detective detective" who has risen up the ranks rapidly after a stint undercover.

"She’s a very determined and very headstrong and is also a very manipulative person," said Sarah Greene.

"There’s two sides of her personality and she is fighting with her darker side as the story evolves."

"[Rob and Cassie] have a shared guilt of surviving. They both survived traumas in their past and that binds them together."

Who is Sarah Greene?

Sarah is best known for her role as Hecate Poole in Penny Dreadful and has also starred in the TV series The Assets, Ransom and Psych Ward. She recently appeared on the big screen in the films Black 47 and Burnt.

If the shows goes on to get a second series, the format is expected to follow the style of the books with new lead characters taking over – which would mean Frank taking over the direction of the show.

In this series, Frank looks after the Undercover team.

"I would describe Frank as a renegade," said Vaughan-Lawlor. "And I suppose he is really an anarchic, he is irreverent and anti-establishment and his moral code is ambiguous."

He hand-picked Cassie for her undercover role and the pair have a “paternal and sexual” relationship.

"He’s not a villain, but not quite a goodie," he added.
