'Then they proceeded to scan the sky, roving from planet to star, from single stars to double stars, from double to coloured stars...'
Two on a Tower 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 ten years her junior. Her husband's death leaves the lovers free to marry, but the discovery of a legacy forces them apart. This is Hardy's most complete treatment of the theme of love across class and age divides, and the fullest expression of his fascination with science and astronomy.
