Georgette Heyer is immoral? I defy you to find anything in her work, which is set in the Regency period of England, that would tittilate my Great Aunt Mary.
I agree with you on other points though.
OK OK. But some people titillate faily easily. For instance ... oh heck, I don't have to reveal everything about my chaotic, fast-access emotional life, do I?
I'll spare you. Hmph. You have no idea what anarchic passions are hidden my placid and matronly exterior. I'm going to go make some soup, and think some edifying thoughts. :o)
