Colin Fischer doesn't like to be touched. Or the colour blue. He avoids eye contact unless absolutely necessary. Sherlock Holmes has a place of honour on his wall. His room is a shrine to clear-headed logic. When a phone rings loudly in class, Colin can't cope. So he barks like a dog. But when a gun goes off in the school cafeteria he isn't scared. He's curious . . . Colin Fischer is determined to discover who fired that gun.
