A Distant Grave
From Tessa's list on atmospheric mysteries that transport you to a dark place.
This is an evocative mystery with not one but two atmospheric settings: Long Island’s Suffolk County, and Ireland’s County Clare. When an Irish national is found dead on a Long Island beach, Detective Maggie D’arcy’s planned vacation to Ireland becomes a tense investigation into the mysterious victim’s death, and a fight to keep her young daughter safe both abroad and back at home. I found A Distant Grave to be deeply chilling and impossible to put down.
