The Fall season 3 trailer: Gillian Anderson and Jamie Dornan return for the BBC drama's final series

It's been almost two years since we left DCI Stella Gibson cradling wounded serial killer Paul Spector as The Fall series 2 drew to a close.

The BBC has now provided a first look at the upcoming series which is confirmed to be the BBC Two drama's last.

The cryptic trailer shows Gibson (Gillian Anderson) swimming as she recalls words spoken by the murderer in series 2's final episode.

"I live at a level of intensity unknown to you and others of your type. You will never know the almost God-like power that I feel when that last bit of breath leaves a body. That feeling of complete possession," we hear him say.

Despite the character's life hanging in the balance, Dornan is confirmed to return for the third and final outing.

The Fall, created and written by Allan Cubitt, first aired in 2013 with the follow-up arriving a year later. The psychological thriller follows Gibson's hunt for Spector, a married father who attacks young professional women in Belfast.

Merlin actor Colin Morgan will return as DS Tom Anderson, alongside previous series regulars John Lynch, Valene Kane, Emmett J Scanlan, Stuart Graham, Bronagh Waugh and Aisling Franciosi.

During the show's hiatus, Anderson starred in Fox's X-Files reboot while Dornan jumped to cinema screens for E.L. James adaptation Fifty Shades of Grey.

There is currently no release date set for the new series, but it'll arrive this autumn.
