Praying for Sleep by Jeffery Deaver

Michael Hrubek, a young schizophrenic, has escaped from a hospital for the criminally insane. And he’s making his way towards Lis Atcheson, the teacher who testified at his trial.

Four people are racing to intercept him before he finds her. His psychiatrist; the hospital director; a professional tracker. And Lis’s husband, who plans to stop Hrubek before the madman reaches his wife.
