No Cure for Love by Peter Robinson (Author)

You think you do not know who I am, but you do. They took you away and Seduced you and stole you from me, just as the others did before. They have tried to blot out your Memory of me...  But everything is clear now... At first, British TV star and recent Los Angeles transplant Sarah Broughton thinks the letters she has been receiving are from a typical fan — someone a little strange, perhaps, but harmless. But when her admirer — who identifies himself only as “M” — starts threatening Sarah and her loved ones, she turns to detectives Arvo Hughes and Maria Hernandez of the LAPD Threat Management Unit and experts in pursuing the most dangerous of stalkers. Pitted against a frighteningly twisted mind, the detectives test their expertise and experience to the limit in the desperate race to save Sarah’s life.
