Gone

When Sarah Polly vanishes, her husband Michael—respected headmaster of a prestigious private school—becomes the obvious suspect.

DI Annie Cassidy, instinctive and relentless, is assigned the case and quickly senses something off: Michael is calm, controlled, and unreadable, as if grief is a performance he refuses to rehearse. Against the backdrop of the school’s closed ranks, a foreboding nearby forest, and the quiet sprawl of Bristol, Annie’s investigation turns into a high-stakes psychological duel. Each interview peels back another layer of privilege, prejudice, and buried trauma, while the Pollys’ daughter Alana—herself a teacher at the school—finds her family pulled into the centre of the storm. The truth feels close. But certainty is the most dangerous illusion.
