Detective Inspector Stefan Gillespie is called to an isolated mountain town in Wicklow, Ireland, in December 1939, after a postman disappears and is believed dead. The local guards in Laragh, close to where Stefan’s wife Maeve drowned in a lake years earlier, are hiding something. When his investigation reveals a link between the missing man and his wife’s death, he travels to Spain in the aftermath of its bloody civil war to find information that will allow him to return to Dublin to find the truth he craves.
