STATE PATHOLOGIST TERRY O'BRIEN IS ABOUT TO TAKE ON HER TOUGHEST ROLE YET.

Tasked with leading the Open Case Review Unit, her usual post-mortem work has been extended to cold-case investigation into unsolved suspicious deaths. And the past is catching up fast. When the body of a garda detective is found mutilated and dumped on gangland ground, a large-scale hunt for those responsible begins.

But when Terry's autopsy exposes evidence the investigation would rather ignore, she finds herself pushing against powerful forces. Then a breakthrough in one of her cold cases hits closer to home. Can the identity of her sister Jenny's killer finally be uncovered? Digging deeper though means unearthing secrets someone is desperate to keep buried.
