I just finished Honeymoon by James Patterson. It is a murder mystery set in New York. The main character, John O’Hara, is an FBI agent who begins investigating a billionaire’s fiancee after he turns up dead. As the book goes on O’Hara discovers more information that causes him to solely focus on the billionaire’s fiancee. I don’t want to tell you about the whole book so I’ll just suggest you read it.
