Query: A very good book ruined

I was reading this book and enjoying it. In the middle of the book, there are a few pages of photographs of different stages of the suspect/defendant's life. The captions next to the photos give away the story. How stupid was that. The captions ruined this book for me. Why finish it, I already know the outcome. Very disappointing.
