Those of you who got sucked into the tension-filled hugely successful BBC drama Doctor Foster have no doubt been chomping at the bit for this second season. Starring Suranne Jones in the titular role, it picks up two years after the events of season one, which saw Gemma Foster discover that her husband Simon (Bertie Carvel) was having an affair with a friend's daughter Kate (Jodie Comer). Gemma has started a new life now in Parminster and may even have a romance on the horizon but she is soon brought back to the past with the arrival of Simon, who from what we can see, is still with Kate, and as you might expect, it's not long before trouble is brewing.
