内容简介：
A mysterious female patient is admitted to Westbury Hospitalas psychiatric unit. She is presumed delusional because of claims that she sees spiritual entities. However, the psychiatrist in charge of the unit soon begins seeing things, too. Dr. Reinhardt is in charge of the psychiatric program, and his atheism has never been so tested. He cannot rationalize the dreams of his patients, from which they are able to detail the physical characteristics of this unsettling patient without having ever seen her. Nor can he make sense of the sinister apparitions they describe in strikingly similar detail. When the gnarled creatures flash their eyes at him, even in waking hours, his struggle with disbelief intensifies. At the same time, Dr. Reinhardt must investigate an assault upon one of his patients and consider a lucrative, yet possibly unscrupulous, job offer that has been presented to him. A current of espionage begins to weave itself through both matters as the tale unfolds.
