Uh-oh. Look who looks like he’s playing a killer – again! Yes, it’s former Emmerdale star Dominic Power, who terrorised the village as killer Cameron Murray…

Dominic guest stars as a deeply disturbed potential murderer in Suspects, which returns for the second half of its first series.

Set in a London police station, Suspects tells very gritty, powerful stories, with actors improvising their dialogue.

It’s an impressive cast, which is led by Fay Ripley (Cold Feet, Monday, Monday, Reggie Perrin) as DI Martha Bellamy and includes Being Human’s Damien Molony as DS Jack Weston and Clare-Hope Ashitey as DC Charlotte “Charlie” Steele.

The video preview also reveals another familiar face: ex-EastEnders’ Charlie Brooks (killer Janine).

Filming of series two is already under way and promises to be just as powerful as the first series.

Rape, drug abuse, euthanasia, the show doesn’t avoid difficult stories.

“The second series is very similar in that regard,” Damien told the Express. “The stories are exciting, thought-provoking, and worrying, but these things happen all the time. It’s not science fiction. It’s reality.”
