The village of Kilbane in County Cork, Ireland, has a new garda-and her first case is a grave matter indeed... It's official! Siobhán is now Garda O’Sullivan, and her five siblings couldn’t be prouder. While brother James runs Naomi’s Bistro, Siobhán is doing her part to keep the village safe. Of course, Kilbane is pretty quiet compared to a place like Dublin, where Macdara Flannery has gone to be a detective sergeant. Then one night the local priest summons Siobhán to the church cemetery. There’s a dead man in the graveyard-aboveground. He lies shot on a blanket of freshly fallen snow, hand stretched out toward a nearby headstone. He’s a stranger, but the priest has heard talk of an American tourist in town, searching for his Irish ancestor. A detective sergeant is dispatched from Dublin to assist with the case, and as fate would have it, it’s Macdara. After his parting, things are awkward between them, but they have to work together. They learn the victim was from Dublin-Dublin, Ohio, that is. And when his family members are located and told of his murder, the plot thickens. Siobhán begins to dig for a motive among the gnarled roots of the family tree. But as long-buried secrets are unearthed, she and Macdara will need to stay two steps ahead of the killer or end up with more than one foot in the grave.
