You Belong to Me by Mary Higgins Clark has been made into a Movie for Television. I am using it as Y for A-Z challenge.
Dr. Susan Chandler has a radio show and she is having a week about why women should be safety conscious in social situations. She invites a psychiatrist, Donald Richards, who wrote a book called Vanishing Women which is about cases he was involved in. Susan decides to bring up the Regina Clausen disappearance as she used to watch her on CNBC. Ms. Clausen disappeared after disembarking from a world cruise. What Susan does not know is that Regina's killer had the radio on and he heard the promo for Susan's show.
Susan receives a call from a Karen who met someone on a cruise who gave her a ring and she was going to fly to Tangiers with him but her husband called and she decided to give their marriage another chance. The ring was engraved "You belong to me". From the sound of the caller's voice, Susan was sure that was not her real name and asked her to come to her office the next day. Unfortunately, the caller is hit by a car - the police do not know if it was an accident or not. But, one woman says she saw someone push her. Dr. Susan is not aware of this. The witness is killed and it is not the last murder.
Susan does all she can to find out what happened to Regina. She gathers clues and even winds up ordering pictures from two ships looking for the man that was next to Regina. While she is doing this she uncovers the fact that Mrs. Jane Clausen, Regina's mother is being scammed by her lawyer, Douglas Layton. Susan finds out that she may know the killer and that she may also be a target.
This book is very easy to read. We do not know who the killer is until Susan finds out. There are many possibilities along the way. It is very easy to make the connection to the song "You Belong to Me" before Susan does as we get to follow the killer's search for the feathers that have scattered in order to cover his tracks. It is one of the most interesting books I have read.
