The problem was this schoolyard. It was a block wide, with entrances on two streets. The street on the north was Challenger territory, and the street on the south was Scarlet Raider territory, and both sides claimed the schoolyard. There had been a few skirmishes, a few guys from both gangs had been jumped and knocked around a little, but that had been all. Finally, the War Lords from the two gangs had met, and determined that the matter could only be settled in a war. The time was chosen: Hallowe'en. The place was chosen: the schoolyard. The weapons were chosen: pocket knives and tire chains okay, but no pistols or zip-guns. The time was fixed: eleven P.M. And the winner would have undisputed territorial rights to the schoolyard, both entrances. The night of the rumble, the gangs assembled in their separate clubrooms for last-minute instructions. Debs were sent out to play chicken at the intersections nearest the schoolyard, both to warn of the approach of cops and to keep out any non-combatant kids who might come wandering through. Judy Canzanetti was a Deb with the Scarlet Raiders. She was fifteen years old, short and black-haired and pretty in a movie-magazine, gum-chewing sort of way. She was proud of being in the Auxiliary of the Scarlet Raiders, and proud also of the job that had been assigned to her. She was to stand chicken on the southwest corner of the street. Judy took up her position at five minutes to eleven. The streets were dark and quiet. Few people cared to walk this neighborhood after dark, particularly on Hallowe'en. Judy leaned her back against the telephone pole on the corner, stuck her hands in the pockets of her Scarlet Raider jacket and waited. At eleven o'clock, she heard indistinct noises begin behind her. The rumble had started. At five after eleven, a bunch of little kids came wandering down the street. They were all about ten or eleven years old, and most of them carried trick-or-treat shopping bags. Some of them had Hallowe'en masks on. They started to make the turn toward the schoolyard. Judy said, "Hey, you kids. Take off." One of them, wearing a red mask, turned to look at her. "Who, us?" "Yes, you! Stay out of that street. Go on down that way." "The subway's this way," objected the kid in the red mask. "Who cares? You go around the other way." * * * * * "Listen, lady," said the kid in the red mask, aggrieved, "we got a long way to go to get home." "Yeah," said another kid, in a black mask, "and we're late as it is." "I couldn't care less," Judy told them callously. "You can't go down that street." "Why not?" demanded yet another kid. This one was in the most complete and elaborate costume of them all, black leotards and a yellow shirt and a flowing: black cape. He wore a black and gold mask and had a black knit cap jammed down tight onto his head. "Why can't we go down there?" this apparition demanded.
