The eyes themselves looked dangerous. The man with the gun turned to say to the man at the door, "Keep your shirt on." like the ships in pirate movies. There was so much confusion that it looked as though the bank robbers were going to get away after all. The police cars were aiming the wrong way and, as they'd come down with sirens wailing, there was a clear path behind them. "Come along home," said his mother, grabbing his hand. "We don't want to be involved." "It was the nuttiest thing," said Detective-Sergeant Stevenson. "An operation planned that well, you'd think they'd pay attention to their getaway car, you know what I mean?" Detective-Sergeant Pauling shrugged. "They always slip up," he said. "Sooner or later, on some minor detail, they always slip up." "Yes, but their tires block away." "Maybe they didn't notice it when they stole the car," said Pauling. "For a well-planned operation like this one," said Stevenson, "they made a couple of really idiotic boners. It doesn't make any sense." my insurance company." "Good. The car's in the police garage, around the corner. If you'd come "Well, why not?" demanded Hastings belligerently. "If I'm making just a quick stop—I never spend more than five minutes with any one customer—I always leave the keys in the car. Why not?" "The car was stolen," Stevenson reminded him. Hastings grumbled and glared. "It's always been perfectly safe up till "What in the name of God is that? You didn't tell me a bunch of kids had stolen the car." about anything.

Murder!" At this point, neighbors called the police. One In the meantime, Mister Higgins had barricaded himself in his house, firing at anything that moved. undershirt, stalking from window to window on the second floor of the house. The show lasted for nearly an hour. There were policemen everywhere, corner, where the police had roped the block off, and occasionally Mr. Higgins would stick his rifle out a window and shoot at somebody. The police used loudspeakers to tell Higgins he might as well give up, they had the place surrounded and could eventually starve him out anyway. neighbors went home and telephoned their friends. On-duty policemen had been called in from practically all of the patience. "What are you trying to prove?" "I don't know. All I know is it's the nuttiest thing I ever saw. And what about the getaway car? What about those tires melting?" trunk?" "How do I know?" demanded the captain. "Kids put it on before the car was stolen, maybe. Or maybe the hoods did it themselves, who knows? What do they say?" "They say they didn't do it," said Stevenson. "And they say they never saw it before the robbery and they would have noticed it if it'd been there." desperately. "How should I know? And why not, anyway? You know as well as I do these things happen. A bunch of teen-agers burgle a liquor store and they write 'The Golden Avengers' on the plate glass in lipstick. It happens all the time. Why not 'The Scorpion'? It couldn't occur to two people?" III Hallowe'en is a good time for a rumble. There's too many kids around for the cops to keep track of all of them, and if you're picked up carrying a knife or a length of tire chain or something, why, you're on your way to a Hallowe'en party and you're in costume. You're going as a 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. 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 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." "Because I said so," Judy told him. "Now, you kids get away from here. Take off." "Hey!" cried the kid in the black-and-yellow costume. "Hey, they're Judy wasn't sure what to do next. If she abandoned her post to chase the one kid who'd gotten through, then maybe all the rest of them would come running along after her. She didn't know what to do. A sudden siren and a distant flashing red light solved her problems. "Cheez," said one of the kids. "The cops!" "Fuzz!" screamed Judy. She turned and raced down the block toward the off their gang jackets and throwing them away, whooping and hollering. They were making such a racket themselves that they never heard Judy's warning.

"Did you see that thing about the gang fight up in Manhattan?" the problem with this one? These kid gangs have names, so what?" him. "One of them was the Scarlet Raiders and the other gang was the "Both gangs? Simultaneously? To the same name?" something," said Hanks severely. "They heard the police sirens, and they threw all their weapons away. Then they threw their jackets away, to try to make believe they hadn't been part of the gang that had been fighting. But they were caught before they could get out of the schoolyard. If the squad cars had showed up a minute later, the schoolyard wouldn't have had anything in it but weapons and jackets, and the kids would have been all over the neighborhood, nice as you please, minding their own business and not bothering anybody. freezing cold and branding names into jackets is just some smart-alec punk's idea of a way to razz the police.
