DARK DRAMA

Dark Angel, 9pm, STV

THE concluding second episode of this absorbing fact-based drama finds the avaricious Mary Ann (Joanne Froggatt, pictured) carrying out what must surely be her most dastardly deed yet — poisoning James’s children. But when her deadly plan goes awry, it seems that her terrible crimes cannot continue to go unnoticed. Will Mary Ann be brought to justice?
