The Widowing of Mrs. Holroyd (1974)

Mrs. Holroyd is married to a loutish miner, who drinks, patronizes prostitutes, and apparently brutalizes her. When a gentlemanly neighbor makes romantic advances to her, she wishes her husband dead. Sooner than she hoped, her wish comes true—when her husband dies in a mining accident. When Charles Holroyd's body is brought home from the mine, and his wife and mother must wash him and lay him out for his funeral, we see for the first time the other side of the relationship between Mr. and Mrs. Holroyd—now, when it's too late.
