A gentle romance begins innocently enough in the stalls of a London theatre where Catherine is enjoying her ninth and Christopher his thirty-sixth visit to the same play. He is a magnificent young man with flame-coloured hair. She is the sweetest little thing in a hat. There is just one complication: Christopher is twenty-five, while Catherine is just a little bit older. Flattered by the passionate attentions of youth, Catherine, with marriage and motherhood behind her, is at first circumspect, but finally succumbs to her lover's charms.
