The Black Swan
 Rosalie, a 50 year old widow, finds her youthful manner diminished by the "organic phenomena of her time of life," or menopause. She lives with her adult, but unmarried, daughter and an adolescent son all of who juxtapose youth and her "superannuated" purpose in life. The family hires a young, American-born man to tutor for her son. Rosalie is strongly attracted to him and is soon infatuated. Her abnegating daughter disapproves more strongly now of her still socializing mother. Then, seemingly miraculously, Rosalie's menopause reverses. Where her vitality, and sexual awareness would be in decline, she is in a heightened state of sexual awareness including the return of menstrual bleeding. Rosalie plans a family trip and declares her intentions and availability to the young man. They plan a liaison in the Rhine castle Schloss Benrath, but it never takes place, however. She is found dead of a hemorrhage caused by a metastatic tumor in her uterus. The surgeons' commentary include a discussion on the possible causes of Rosalie's newfound youth. Cancer was an obvious cause of her tumor, but one doctor supposes that it could have been the yearning for love and her altered or re-awakened erotic personality that stimulated her ovaries thereby causing the cancerous growth.
