The house sitter - Peter Lovesey

The identification of the woman found murdered on Whiteview Sands poses more questions than it answers. Emma Tysoe was a respected psychologist and an official criminal profiler with several successful cases to her credit. Why was she sun-bathing alone so far from home? How did she get there? Who is the mysterious 'Ken' in her private life? What was the murder weapon? Why did the man who noitce she was dead then completely disappear from the scene? When Peter Diamond is brought into the investigation he sheds some light on these matters - most importantly by discovering that she had been seconded under the greatest secrecy to work on the profile of the person who has assassinated one celebrity and is threatening to kill more. Are these killings connected to Emma's death? Diamond thinks so, but he cannot persuade his colleagues to agree with him, and even he cannot make all the pieces fit the jigsaw he's envisaged.
