Dublin Murder Squad series number three by Tana French. Back in 1985, Frank Mackey and Rosie Daly are set to run away together: go to London, marry, get good jobs, leave inner city Dublin and their dysfunctional families behind. But on the night they were to leave, Rosie doesn't show. Frank, at nineteen, thought his family was too crazy even for her and she'd given him the brush-off. He never went home again. Neither did Rosie. Everyone assumed she went to England on her own. Until her suitcase shows up in a run down house 22 years later. Now Frank is back in Faithful Place with his family and old neighborhood trying to figure out what happened to Rosie. But he's a detective now; the neighborhood doesn't trust the police on principle. The police handling the case won't talk to him, in case family and neighborhood loyalty make him a liability. What will Frank sacrifice to discover the truth?
