No Comfort for the Dead - R.P. O'Donnell

After witnessing a murder, a small-town librarian is forced to act when the local police arrest the wrong man, perfect for fans of Dervla McTiernan and Carlene O'Connor.

1988, West Cork, Ireland. Emma Daly has returned to her home in Castlefreke, a small and peaceful village where everybody knows everybody. She has taken over the local library and is trying not to think about the scandal she left behind in the city. But when the richest man in the village is murdered and the main suspect is the mysterious son of a local family, her charming small-town life is turned upside down.

Emma knows for a fact that there is more to the story, and when the family asks her to investigate, she decides to take matters into her own hands.

Teaming up with a stubborn widow, an elderly hypochondriac, and her high school sweetheart, it is up to Emma to solve the mystery before either the police or the murderer can stop her.
