Two missing girls. No suspects. And a killer who escaped justice.

In 2005, fifteen-year-old Callie Thomas disappeared after a night out in rural Wales. Six months later, another teenage girl vanished from a nearby village. Neither case was ever solved.

Twenty years later, the past refuses to stay buried.

When true-crime investigator Nell Aubury goes missing while looking into one of the disappearances, DI Winter Meadows is forced to reopen the cases a community has spent decades trying to forget.

Then a new body is found, buried beneath ancient burial stones.

Meadows is determined to chase down this fresh lead to get to the truth, but all he finds are dead ends. Witnesses change their stories. Old statements are full of holes.

Someone has already killed to keep their deadly secrets buried. How far are they prepared to go to stop Meadows from learning the truth?
