Patrick Conroy, a young American student of medicine in Dublin, decides to take a break from the hustle and bustle of the big city and spend a month in the quietude of the wild and beautiful Glencree valley, County Wicklow. However, surrounded by local legends and myths, he is soon dragged into an ancient mystery that has haunted the village of Ballymoor for centuries. Set on the background of the tumultuous years preceding the War of Independence, and colored by Irish folklore, the Haunter of the Moor is a ghost story written in the style of Victorian Gothic novels.
