Roy would not have noticed the strange boy if it weren't for Dana Matherson, because Roy ordinarily didn't look out the window of the school bus. He preferred to read comics and mystery books on the morning ride to Trace Middle. But on this day, a Monday (Roy would never forget), Dana Matherson grabbed Roy's head from behind and pressed his thumbs into Roy's temple, as if he were squeezing a soccer ball. The older kids were supposed to stay in the back of the bus, but Dana had snuck up behind Roy's seat and ambushed him. When Roy tried to wriggle free, Dana mushed his face against the window. It was then, squinting through the smudged glass, that Roy spotted the strange boy running along the sidewalk. It appeared as if he was hurrying to catch the school bus, which had stopped at a corner to pick up more kids. The boy was straw-blond and wiry, and his skin was nutbrown from the sun. The expression on his face was intent and serious. He wore a faded Miami Heat basketball jersey and dirty khaki shorts, and here was the odd part: no shoes. The soles of his bare feet looked as black as barbecue coals. Trace Middle School didn't have the world's strictest dress code, but Roy was pretty sure that some sort of footwear was required. The boy might have been carrying sneakers in his backpack, if only he'd been wearing a backpack. No shoes, no backpack, no books—strange, indeed, on a school day. Roy was sure that the barefoot boy would catch all kinds of grief from Dana and the other big kids once he boarded the bus, but that didn't happen. ...Because the boy kept running—past the corner, past the line of students waiting to get on the bus; past the bus itself. Roy wanted to shout, "Hey, look at that guy!" but his mouth wasn't working so well. Dana Matherson still had him from behind, pushing his face against the window. As the bus pulled away from the intersection, Roy hoped to catch another glimpse of the boy farther up the street. However, he had turned off the sidewalk and was now cutting across a private yard—running very fast, much faster than Roy could run and maybe even faster than Richard, Roy's best friend back in Montana. Richard was so fast that he got to work out with the high school track squad when he was only in seventh grade. Dana Matherson was digging his fingernails into Roy's scalp, trying to make him squeal, but Roy barely felt a thing. He was gripped with curiosity as the running boy dashed through one neat green yard after another, getting smaller in Roy's vision as he put a wider distance between himself and the school bus. Roy saw a big pointy-eared dog, probably a German shepherd, bound off somebody's porch and go for the boy. Incredibly, the boy didn't change his course. He vaulted over the dog, crashed through a cherry hedge, and then disappeared from view. Roy gasped. "Whassamatter, cowgirl? Had enough?" This was Dana, hissing in Roy's right ear. Being the new kid on the bus, Roy didn't expect any help from the others. The "cowgirl" remark was so lame, it wasn't worth getting mad about. Dana was a well-known idiot, on top of which he outweighed Roy by at least fifty pounds. Fighting back would have been a complete waste of energy. "Had enough yet? We can't hear you, Tex." Dana's breath smelled like stale cigarettes. Smoking and beating up smaller kids were his two main hobbies. "Yeah, okay," Roy said impatiently. "I've had enough." As soon as he was freed, Roy lowered the window and stuck out his head. The strange boy was gone. Who was he? What was he running from? Roy wondered if any of the other kids on the bus had seen what he'd seen. For a moment he wondered if he'd really seen it himself.
