Karen White

Karen White arrives in Broadchurch as a national journalist, sharper and more press-savvy than the local reporters already circling the case. She's writing a book on the murder, professionally curious and quietly relentless, probing witnesses and investigators alike with a directness that unsettles a town still raw with grief.

McClure plays her with a coiled, watchful intelligence that never tips into caricature — you sense a real reporter's instincts under the ambition. The show uses her as an outside eye on a closed community, and McClure makes her scepticism feel earned rather than cynical, someone worth trusting even when no one around her does.
