Sarah Thomas is a New Jersey housewife whose lying cheating husband leaves her for a younger woman with a trust fund. Instead of falling apart from grief, she converts everything she owns to cash and goes on an adventure. She has always wanted to go to Ireland and when she gets there she finds a new life, a better life than she ever dreamed of. She has friends, wealth, and a large new extended family to care for her. Why would she risk all of that to solve a thirty year old mystery? That is exactly what she does with the help of an elderly retired school teacher, and in the process she comes to realize how precious life is. Evelyn Carlton had had a hard life. She didn't deserve to die the way she did. When her spirit takes up residence outside the fences of Braunleaven estate, she disrupts Sarah's morning horse-back ride and starts Sarah on a dizzying ride of a different sort. By channeling her inner Jessica Fletcher, Sarah investigates the death of Evelyn Carlton, not realizing that she is putting her own life in danger.
