Perfect Nightmare - John Saul

If you open your house to strangers, who knows who might come in. And what they might
be after. Or whom. Now, ponder the unthinkable and surrender to your darkest dread,
as sinister storyteller extraordinaire John Saul weaves a heart-stopping tale of
lurking terror and twisted intent.

Every parent's nightmare becomes reality for
Kara Marshall when her daughter, Lindsay, vanishes from her bedroom during the night.
The police suspect that the girl is just another moody teenage runaway, angry over
leaving behind her school and friends because her family is moving. But Lindsay's
recent eerie claim-that someone invaded her room when the house was opened to prospective
buyers-drives Kara to fear the worst: a nameless, faceless stalker has walked the
halls of her home in search of more than a place to live.

Patrick Shields recognizes
Kara's pain-and carries plenty of his own since he lost his wife and two children
in a devastating house fire. But more than grief draws Patrick and Kara together.
He, too, senses the hand of a malevolent stranger in this tragedy. And as more people
go missing from houses up for sale, Patrick's suspicion, like Kara's, blooms into
horrified certainty.

Someone is trolling this peaceful community-undetected and
undeterred-harvesting victims for a purpose no sane mind can fathom. Someone Kara
and Patrick, alone and desperate, are determined to unmask. Someone who is even now
watching, plotting, keeping a demented diary of unspeakable deeds . . . and waiting
until the time is ripe for another fateful visit.
