Jacob Hunt is a teenage boy with Asperger's syndrome. He's hopeless at reading social cues or expressing himself well to others, and like many kids with AS, Jacob has a special focus on one subject - in his case, forensic analysis. He's always showing up at crime scenes, thanks to the police scanner he keeps in his room, and telling the cops what they need to do... and he's usually right. But then his town is rocked by a terrible murder and, for a change, the police come to Jacob with questions.
