IN THE BALLROOMS AND DRAWING ROOMS OF REGENCY LONDON, RULES ABOUND. FROM THEIR EARLIEST DAYS, CHILDREN OF ARISTOCRATS LEARN HOW TO ADDRESS AN EARL AND CURTSEY BEFORE A PRINCE—WHILE OTHER DICTATES OF THE TON ARE UNSPOKEN YET UNIVERSALLY UNDERSTOOD. A PROPER DUKE SHOULD BE IMPERIOUS AND ALOOF. A YOUNG, MARRIAGEABLE LADY SHOULD BE AMIABLE… BUT NOT TOO AMIABLE.
