London, 1814:

A young woman inherits an interesting London house, Number 14 Beaulieu Crescent. Nothing unusual in that, you might say. And ordinarily you'd be right. But this time the "house" is actually a high-class brothel, and the young woman has a secret identity of her own that she must never reveal. Especially not to the man who brings her body to life, stirs her senses like no other, and who has begun his own campaign to unlock the mystery that is "Madam Charlie".
