The kids were still yelling at the top of their voices, but the thundering of heavy, flat feet galumphing up from the lower depths couldn't be ignored for long. All the boys noticed it at about the same time. They jerked their heads round to face the stairway. Malone and his campatriots crouched lower behind the boxes.
Mike Fueyo was the first to speak. "Don't vanish yet!" he snapped. "Let's see who it is."
The internal dissent among the Silent Spooks disappeared as if it had never been, as they faced a common foe. Once again, they fell naturally under Fueyo's leadership. "If it's cops," he said, "we'll give 'em the Grasshopper Play we worked out. We'll show 'em."
"They can't fool with us," another boy said. "Sure. The Grasshopper Play."
It was cops, all right. Lieutenant Lynch ran up the stairs waving his billy in a heroic fashion, followed by a horde of blue-clad officers.
"Where's Malone?" Lynch shouted as he came through the doorway.
"Where's your what?" Mike yelled back, and the fight was on.
Later, Malone thought that he should have been surprised, but he wasn't. There wasn't any time to be surprised. The kids didn't disappear. They spread out over the floor of the room easily and lightly, and the cops charged them in a great blundering mass.
Naturally, the kids winked out one by one—and reformed in the center of the cops' muddle. Malone saw one cop raise his billy and swing it at Mike. Mike watched it come down and vanish at the last instant. The cop's billy descended on the head of another cop, standing just behind where Mike had been.
The second cop, hit and blinded by the blow on his head, swung back and hit the first cop. Meanwhile, Mike was somewhere else.
