Just Take My Heart by Mary Higgins Clark

This is vintage Mary Higgins Clark. There's a murder and a suspect and I think I know who did it but you know there is always some kind of twist. There are actually two story lines. One is the murder of actress Natalie Raines. Her soon-to-be ex-husband (and agent) is arrested and is brought to trial. The prosecutor is Emily Wallace. She is a young widow with a dog given to her by her father. She happens to be living next to a serial killer (from Iowa, no less - where did Clark get that idea????). Oh yeah, there is also a heart involved! Easy, entertaining read by one of the most consistent authors.
