Faithful Place by Tana French. ***

I've seen this author's name before, but didn't take much notice of it. Then Imwas browsing through the mystery section at PCB Library, discovered she is an Irish writer, and sets her stories in Ireland, so I decided to read one of her books. This is a very Irish story, set in Dublin, and involving the family members of an undercover cop, Francis Mackey, an extremely dysfunctional family at that. Twenty years earlier, Francis was prepared to leave Ireland with his sweetheart, Rosie, but the night she is to meet him to leave together, she fails to show up. After twenty years, her suitcase is discovered and soon after that, her body, so Francis returns to Dublin  to solve the mystery of why she didn't leave and who murdered her.
