Mind Prey (A Prey Novel, Bk. 7)

Psychiatrist Andi Manette—estranged wife of a Minnesota developer—and her two young daughters have been kidnapped. It's a high-profile case that draws the attention of Lucas Davenport, who learns that the kidnapper is John Mail, an ex-patient of Manette's who was once confined to an institution for the criminally insane.

But Davenport suspects this could be more than a madman entertaining his violent fantasies, because several people stand to benefit from Manette's death. Now, in an isolated farmhouse, Mail's sick game begins, but it's Davenport's endgame that means life and death.
