He nodded wearily:

"That's what confounds us with this syndrome. The patients are 'normal' by any definition of this word that you care to adopt. They are only convinced that family members, friends, even neighbors are being substituted for - and, of course, they are not."

"Soon, she will begin to doubt you and then herself. Next time she catches her own reflection in a mirror or a window, she will start to question her own identity. She will insist that she has been replaced by an entity from outer space or something. She is bad news. The literature describes the case of a woman who flew into jealous rages at the sight of her own reflection because she thought it was another woman trying to seduce her husband."

Milton's pained expression deepened:

"Then you are faced with only one alternative: psychodrama. To save her, you must enter her world, as convincingly as you can. Play her game, as it were. Pretend that you believe in her lunatic delusions. Act the part."
