Two On A Tower" (1882) is a tale of star-crossed love in which Hardy sets the emotional lives of his two lovers against the background of the stellar universe. The unhappily married Lady Constantine breaks all the rules of social decorum when she falls in love with Swithin St. Cleeve an astronomer who is ten years her junior. Her husbands death leaves the lovers free to marry but the discovery of a legacy forces them apart. This is Hardys most complete treatment of the theme of love across the class & age divide & the fullest expression of his fascination with science & astronomy."
