What does it take to challenge a Rake?

Suppose you were one of Regency London's most notorious rakes; drinking, gambling, racing, having your pick of exquisite women and all to excess, when and where you wish. No matter how scandalous your latest excess is, everyone fawns on you. Bor-ing!! The pattern of your life has become too predictable....but then you chance upon an innocent girl being molested by a pair of drunken young bloods. She has no one else to help her, so you have to advise her - and dammit!! - rescue her - not once but time after time. The chit has her own outrageous ideas of living a life of adventure but she always ends up in trouble. Can't have that, by Thunder! Can it be that you have a spark of decency in you? That shocks you so much it takes a bottle or two of brandy to drown the idea. But you can't abandon your protegee...not when your mistress is out to ruin her and the Prince Regent has a lascivious eye on her.
