Marcella
itv, Monday 19 March, 9pm
Marcella and Rav’s hunt for their serial child killer ramps up this week, when they are able to deduce the area that Adam was picked up from, which leads them to an abandoned house with a gruesome history and reveals the true extent of the crimes that their killer has committed. Bonkers, but gripping. Meanwhile Marcella’s son, Edward, continues to show signs of being a little “kooky” as he spends the episode prodding dead animals.
