The rakish, horse-loving Marquis of Ardsley boasts that he tan always appraise a woman's social breeding at first sight--so two of his young club-mates, Lord Frodham and Sir James Overton, secretly decide to put the Marquis to the test. And, luckily enough, Frodham and Overton promptly meet beautiful Indira Rowlandson at a highway inn: just arrived from India, she's the orphaned daughter of a rich trader (non-blue-blood)--yet, after rescuing her from a forced marriage, Frodham and Overton feel sure that Indira's demure and classy enough to fool the Marquis. Thus, helpless waif Indira timidly agrees to join the party at the Ardsley estate, where she soon wins the Marquis over entirely (especially since she's his match at steeple-chase riding and aloofness). But when Indira finds herself falling in super-vibrating Love with the Marquis (her predestined ""Gum""), she feels guilty about the deception, runs away . . . and must be retrieved from London for the usual Cartland fadeout: ""he knew that the love pulsating through both of them and which made them already one person was also Divine."" With dib-dabs of steeple-chasing, Chinese poetry, Eastern mysticism, and unapologetic racism--a Regency fillip for Cartland regulars only.
