Remembrance of Things Past – volume 3 (1981).

Inspector Martin Aitken’s life is a mess. Divorced, his career’s in chaos, and the last thing he needs is a collapsed woman in the street on Christmas Eve. Ellen Donnelly is a woman on a mission, coming to Ireland to find her mother and escape her husband. Milton Amery is her husband, an unfaithful New York plastic surgeon.

All three of their roads leads to Inishowen.
