As the tense psychological thriller returns, you’d be forgiven for thinking that you had accidentally tuned into an episode of Casualty!

The last series ended with sick serial killer Paul Spector (Jamie Dornan) being shot and lying bleeding in the arms of his arch-enemy Detective Superintendent Stella Gibson (Gillian Anderson).

The new run picks up moments later as Spector is rushed to hospital, but will the medics (including one played by Aisling Bea) save his life so that dogged Gibson can finally bring him to justice or will death snatch him from her?

Some of the intense hospital scenes are really not for the squeamish!
