An undercover cop reluctantly returns to the Irish neighborhood where he grew up when a discovery in an abandoned house forces him to reconsider the event that changed his life over 20 years ago. Though technically part of the Dublin Murder Squad series, this novel functions perfectly well as a standalone. Tana French takes a deep dive into a segment of Irish culture when Frank Mackey returns to the family he abandoned and ignored (with the exception of one sister) when he left to make a career for himself years ago. Faithful Place is a street of tenement houses in The Liberties, an old section of Dublin, where money and education are scarce but alcohol, abuse, and obligation are plentiful. Frank has no desire to return but he can’t turn his back on the chance to finally know what happened the night in 1985 when he and Rosie Daly were supposed to leave Faithful Place and start a new life together. I highly recommend the audiobook as the narrator captures Dublin Irish vernacular beautifully.
