The Hellfire Club — Peter Straub

They are dying, one by one: wealthy middle-aged women in an exclusive Connecticut suburb. Their murderer remains at large. Nora Chancel, wife of publishing scion Davey Chancel, fears she may be next. After all, her past has branded her a victim. . . .

Then Davey tells Nora a surreal story about the Hellfire Club, where, years before, he met an obsessed fan of Chancel House's most successful book, Night Journey -- a book that has a strange history of its own. . . .

Suddenly terror engulfs Nora: She must defend herself against fantastic accusations even as a madman lies in wait. And when he springs, Nora will embark on a night journey that will put her fears to rest forever, dead or alive. . . .
