The ending is a mess and has a fatal flaw either way you interpret it. If J. Shaw did not know that her husband was the kidnapper then what was her end game in hiding her daughter and getting everyone involved in a fake kidnapping.

On the other hand, if she did know and the scheme was designed to open up the cold case and assist the police and Lainey in solving the case while her daughter is safe in hiding with her family; then all she needed was a DNA test. A piece of Olivia’s hair would identify her husband Tom as the biological father and therefore Lainey’s kidnaper.

Either way the book fails
