Margaret Wells has been deeply, hopelessly in love with the handsome, dashing Richard Adair, Earl of Brampton, since she met him at a masquerade ball six years ago. Passion had flared between them then, but she had fled before the time for unmasking. Now Richard merely needs a wife to give him an heir, and the quiet, demure Miss Wells seems as suitable as anyone else. Margaret, longing to ignite some sort of passion in her dull marriage, wonders what would happen if she were to become that masked enchantress once more and met her husband by chance in some secluded, romantic setting. Little does Margaret suspect that Richard has never forgotten the nameless charmer for whom he had searched in vain for weeks and months after the masquerade ball. And little does she suspect that he is falling in love with his wife.
