Overview: When a judge is murdered in Griffith Park, Brenda's investigation takes an unexpected twist. Her best witness, or perhaps her prime suspect, is his teenaged son with autism. Challenged by the boy's behaviors, but convinced he has the clue to unraveling the case, Brenda must try to understand his disability, and thereby learn what he knows. Meanwhile, she must keep his mother, and the child protective system from taking custody of the boy, limiting her access to him, and the killer.
