Meet Detective Anna McArthur. Back at work after being stabbed in the line of duty. And solving serious crimes in West Norfolk.

When the body of reclusive pensioner Barney King is found floating in a winter pond, Detective Constable Anna McArthur expects another lonely death. But in King’s cluttered Norfolk cottage, she finds a handwritten note: a confession to murder.

Forty years ago, a young mother named Clara Burns disappeared without a trace. Her children were asleep in bed. Her husband was down the pub. And her neighbour — Barney King — was the prime suspect.

Now Anna and her team are forced to reopen the case. But when it emerges that King was once suspected in the disappearance of DCI Aaron Burns’ own mother, the pressure intensifies — and so does the scrutiny on Anna’s relationship with her boss.

As an outsider is drafted in to lead the case, secrets swirl around the remote farmhouse, a tight-lipped family, and a carer who knows more than she’s saying. But someone is watching Anna, and they’re ready to protect the past — at any cost.

A chilling, character-driven mystery set in the stark beauty of rural Norfolk.
