There's a gripping new mystery thriller that's just been dropped on Disney+ – and we think it could be your next TV obsession.

Dublin Murders, an eight-part crime drama hailed as a 'breathless whodunnit', is based on the first two novels in Tana French's Dublin Murder Squad series: In the Woods and The Likeness.

While the show initially aired on BBC One and Starz back in 2019, all eight episodes have now landed on Disney+ in the UK and Ireland, as well as remaining on BBC iPlayer.

What is Dublin Murders about?

The eight-part series, set in Ireland, follows two seemingly unrelated murder investigations – each led by a different detective from the Dublin Murder Squad, whose personal lives become entangled with their cases.

The first storyline, adapted from In the Woods, follows Detective Rob Reilly (Killian Scott) and his partner Detective Cassie Maddox (Sarah Greene) as they investigate the murder of a 13-year-old girl in the woods.

The case immediately reopens old wounds for Rob who, as a child, was the sole survivor of a traumatic incident in the same woods, where two other children vanished and were never found. 

Rob's repressed memories and the potential connection to his own past create intense psychological tension throughout the investigation.

The second storyline, adapted from The Likeness, sees Cassie Maddox uncover the murder of Lexie Madison – a woman who looks exactly like Cassie and who has been living under an alias Cassie once used.

Cassie is then pulled into a dangerous undercover operation, posing as the deceased woman to infiltrate a group of enigmatic university students,  in order to uncover the truth.

Meanwhile, RadioTimes commended the show’s refusal to tie up every loose end, noting: "While we're given motives and confessions and full run-downs of how the killings were carried out, some of the larger mysteries are left unexplained. And that's absolutely OK."

Dublin Murders is available to stream on Disney+ and BBC iPlayer now.
