"The Hell-Fire Club was an aristocratic temple of debauchery broken up in 1770. Lord Stoneham revives it in the twentieth century to further his business plans. But is the old Club really dead?"
I liked this. It was actually very well written which you wouldn't expect considering the subject. The main story is about a man who inherts a family manison which needs paying off with money he doesn't have. He starts up the hellfire club and gets in over his head with satanic practices. The ending was a bit to rushed but either way the book was so well written it makes me wish he wrote more books like this
