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 that 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?
