The Brimstone Wedding — Barbara Vine

Superstitious Jenny Warner, who works as a caregiver in a rural nursing home, is dying to confide in someone about her affair with a. married man. The person she talks with is gracious, proud Stella Newland, a new patient, who in her last weeks of dying remembers a passion of her own. As a kinship grows between the two women, Stella gives Jenny a key. It fits a cottage only Stella knows about, where Jenny can tryst in privacy. But for emotionally fragile Jenny it also unlocks a door into Stella's past and a look at the unexpected--a chilling transformation of erotic love into something terrible.
