С 1, с 1: In the summer of 2006, Rob Reilly, a smart-suited homicide detective, and his partner Cassie are dispatched to investigate a child's murder, and they find a community caught between old and new Ireland. On an altar lies the body of a local teenage girl, the precociously talented Katy Devlin. Her body is found in the middle of an archeological site, threatened by local developers aiming to build a shiny new motorway. The neighboring estate, Knocknaree, has never quite gotten its share of the “Celtic Tiger” and has been blighted by poverty and unemployment for generations. Moreover, this is the not the first time a child of Knocknaree has been lost — 21 years earlier, in a very different Ireland, three children went missing, and only one ever came back alive. Memory runs deep in this part of the world, and locals, press and the Dublin Police worry that the cases are linked.
