In , the investigation into the Meredith twins reaches a turning point as DS Lisa Armstrong balances a crumbling case and her own escalating family drama. You can watch the full series on ITVX . Plot Summary
The Meredith family, already fractured by grief, faces new revelations that threaten to destroy what little remains of their unit. The episode excels at portraying the "ugly" side of grief—the anger, the blame-shifting, and the desperate attempts to protect one’s own skin even in the face of tragedy. Atmospheric Storytelling
Critically, Episode 4 refuses to make the Mooneys simple villains. While the audience suspects the twins, the episode lingers on their father, Andy Mooney (Joe Absolom). In a scene shot through a rain-streaked window (a recurring motif in the HDTVrip, emphasizing voyeurism), Andy admits he lost control of his sons long ago. This confession acts as a dark prophecy for Lisa. The episode argues that the true crime is not the stabbing on the promenade, but the years of neglected parenting that led to it. By the end of the episode, the viewer understands that Lisa Armstrong and Andy Mooney are two sides of the same coin.
