Murder is a Nightmare. A Hannah Kline Mystery, #7

Meet Dr. Andrea Marcus. She's a psychiatrist, Dr. Hannah Kline's closest friend, and she has a problem. She's just accepted a new patient, and she's taken an instant dislike to him. Blake Harris is narcissistic, arrogant and controlling. He's in therapy under protest, because his recurrent nightmares are interfering with his sleep and his job as the CEO of a pharmaceutical start-up company. Blake is also sexually obsessed with his new therapist.
The more Andrea learns about her patient, the more convinced she is that his nightmares are hiding a horrific crime, and the deeper she probes his psychopathology, the more frightened she becomes. When Andrea disappears, it will be up to Hannah and her new husband, LAPD detective Daniel Ross, to find her before the unthinkable happens.
