An upper-class woman, recovering from a suicide attempt, visits the women's ward of Millbank prison as part of her rehabilitation. There she meets Selina, an enigmatic spiritualist-and becomes drawn into a twilight world of ghosts and shadows, unruly spirits and unseemly passions, until she is at last driven to concoct a desperate plot to secure Selina's freedom, and her own. "Unfolds sinuously and ominously...a powerful plot-twister. The book is multidimensional: a naturalistic look at Victorian society; a truly suspenseful tale of terror; and a piece of elegant, thinly veiled erotica." ("USA Today") "Gothic tale, psychological study, puzzle narrative-Sarah Waters' second novel is all of these wrapped into one, served up to superbly suspenseful and hypnotic effect." ("The Seattle Times")
