What is Dublin Murders about?

Detectives Rob Reilly (Killian Scott) and Cassie Maddox (Sarah Greene) are at the centre of this new psychological crime thriller, which the BBC says will “deliver a dark psychological mystery with a tap root that drops deep down into Ireland’s past, foreshadows the future and brings insight to its present.”

The series is drawn from crime writer Tana French’s bestselling Dublin Murder Squad novels, and is written by Sarah Phelps – best-known for her Agatha Christie TV dramas and for her adaptation of JK Rowling’s The Casual Vacancy.

Each of the six novels is led by a different detective from the same team, but this eight-part TV adaptation will blend the first two novels – In the Woods and The Likeness – and will focus on detectives Reilly and Maddox.

Dublin Murders

Dublin Murders is set during the height of the Celtic Tiger financial boom of the millennium, and tells the story of two murder investigations led by “ambitious and charismatic” detectives Rob Reilly and Cassie Maddox.

According to the BBC’s synopsis, the victims are “a young talented ballerina who is found dead on an ancient stone altar; and a vivacious free-spirited woman, who is found stabbed in a roofless famine cottage.”

These deaths are seemingly unrelated, “but as we will discover, are actually knitted together by powerful shared themes – the macabre ‘red in tooth and claw’ elements of both stories, and their heart-thumping psychological thriller qualities.”

Writer and executive producer Sarah Phelps said: “Tana’s compelling novels are both nail-biting thrillers, enquiries into the nature of evil and heartbreaking stories of human frailty, love and loss. I couldn’t be more excited to be bringing The Dublin Murders to audiences.”

Saul Dibb, the drama’s lead director and executive producer, said in a statement: “Writers as good as Sarah Phelps are rare and I want people to be as excited to watch Dublin Murders as I was to first read her scripts – with each episode the powerful, gripping, atmospheric, brilliantly acted mini-movie they deserve.”
