Cré na Cille (Graveyard Clay)

This a story about an obsessive hatred that started as a case of jealous rivalry between two young sisters, resulting in a broken heart as Neil got the upper hand on her sister, Caitríona, stealing away from her the man with whom she was in love. Caitríona never forgave her sister, nor would she forgive her as long as she lived, or indeed after that.
