Serial killer Paul Spector, played by “50 Shades of Grey” star Jamie Dornan, seems to be getting even more dangerous in the season two trailer for “The Fall,” released by BBC Two on Sunday.

In the season one finale, Spector dodged the investigation centered on him, led by Detective Superintendent Stella Gibson (Gillian Anderson). As Gibson comes across more clues, Spector goes further into disrupting her personal life.

Along with Dornan and Anderson, Bronagh Waugh, Archie Panjabi, Karen Hassan, Emmett Scanlan, Simon Delaney and John Lynch are also returning for season two. New faces include Colin Morgan, Claire Rafferty, Patrick Fitzsymons, Jonjo O’Neill, Tim Loane and Bronagh Taggart.

Exec producers of “The Fall” include creator Allan Cubitt, Anderson, Stephen Wright, Patrick Irwin and Justin Thomson-Glover. Artists Studios produces for BBC Two.

Season two of “The Fall” is expected to debut in mid-November.
