The team re-investigates the death of a teenage boy who was found on a building site some years ago, drowned in concrete. Part of a human ear is found in his stomach, linking him to the dumping of another seriously injured teenager in a hospital at around the same time. The ground on which the dead teenager was found belongs to a Catholic abbey which is soon to be dissolved, and the abbey owns a shrine which might contain evidence and has to be dismantled - a task which falls to the unwilling Stella Goodman.Meanwhile, new forensic scientist Dr Eve Lockhart makes her mark on the case.
