Beau should have known by the way she carried herself that Capri was a force to be reckoned with. The way she put him in his place one day while on the plane should have been all the evidence he needed to leave her alone. However, after he got over his initial shock, it was brought to his attention by his friend, Caspian, that he needed Capri to seal some very important business deals.
When Beau spied what she was wearing under her clothes, he knew then that she wasn't the normal woman. She had a way about her that was strong and dominating, which he could put up with, if the outcome was to his liking.
But if she thought Beau was willing to be her boy toy, then Capri has another thing coming. And he was going to enjoy proving it her, one erotic experience at a time, that he was not like all the others. Of course, he'd also have to deal with Monica, his conniving ex-wife, showing up in an attempt to putting a stop to his fun, but for some reason...he thought Capri could hold her own.
