Broken

When the body of a young woman is discovered at the bottom of Lake Grant, a note left under a rock suggests suicide. But within minutes it becomes clear this is cold-blooded murder. When Grant County chief medical examiner Sara Linton goes to visit the main suspect, she is met with a horrifying sight - the man is dead in his cell with the words `not me` scrawled across the walls. Special Agent Will Trent is called in to investigate. But who can he turn to when the only person who knows the truth is dead?
