1950s, rural Ireland. A loner comes across a mysteriously empty car in a field. Knowing he shouldn't approach, but unable to hold back, he soon finds himself embroiled in a troubling missing person's case, as a husband claims his wife may have thrown herself into the sea. Called in from Dublin to investigate is Detective Inspector Strafford, who soon turns to his old ally - the flawed but brilliant pathologist Quirke - a man he is linked to in increasingly complicated ways.
