Watch: New trailer for BBC series Dublin Murders

When it was announced that Tana French's Dublin Murder Squad novels would be turned into a BBC series, it was clear that viewers would be in for a dark and twisted thriller. The new trailer for Dublin Murders now shows how dark and twisted it gets.

Set during the heights of Ireland's Celtic Tiger financial boom in the early 2000s, the series focuses on French's first two novels, In The Woods and The Likeness, with detectives Rob Reilly (Killian Scott) and Cassie Maddox (Sarah Greene) investigating the murder of a young girl on the outskirts of Dublin.

Watch the new, dark trailer below:

Dublin Murders reunites Scott with his Love/Hate co-star Tom Vaughan-Lawlor, who plays supporting character Frank Mackey in the upcoming BBC series. Moe Dunford, Sam Keeley and Antonio Aakeel also star in supporting roles.

A few weeks ago, RTÉ revealed that they will air Dublin Murders in their upcoming season. No official premiere date has been confirmed yet, although the newest trailer announces that it's set to debut in October.
