DI Luke Bascombe is the detective leading the investigation, a seasoned officer who carries the case with a weary, methodical steadiness. He is the one who must look Jamie's parents in the eye and lay out the evidence, balancing professional duty against the human horror of arresting a child.
His work takes him into Jamie's school, where the gulf between the adults and the coded online world of the kids becomes painfully clear. It is partly through his own teenage son that Bascombe begins to grasp the hidden language of emojis and incel forums that the case turns on.
Walters plays Bascombe with restraint, a man trying to do right inside a system that feels increasingly out of step with the lives it polices. He becomes the audience's guide through the unfamiliar landscape of teenage radicalisation, as unsettled by what he learns as we are.
