Frampton, Megan, 1964- School for scoundrels (Series) #3

"Simeon Jones has a secret--he is soft-hearted. Despite his scandalous exterior, he will quietly give money to orphans (after all, he was one himself), animals, and damsels in distress. One such damsel is Lady Myrtle Allen--but it's not her funds that are lacking, but rather she needs to get to London--fast. And so begins a wild adventure. First, the pair tells all the ton that they are engaged to be wed--how else to prevent scandal once they are found together--alone! They plan to carry out this deception, fully knowing that once the season is over, they will quietly part ways. But then, they discover that they have fallen in love, which was definitely not part of their plan! Can this scandalous man and adventurous woman turn this pretense into reality?"--
