Sir Philip Rookwood is the disgrace of the county. He's a rake and an atheist, and the rumours about his hellfire club, the Murder, can only be spoken in whispers. Guy Frisby and his sister Amanda live in rural seclusion after a family scandal. But when Amanda breaks her leg in a riding accident, she's forced to recuperate at Rookwood Hall, where Sir Philip is hosting the Murder. Guy rushes to protect her, but the Murder aren't what he expects. They're educated, fascinating people, and the notorious Sir Philip turns out to be charming, kind — and dangerously attractive.
