The two thugs had held back, but now they began edging in. Gordon slipped back behind another truck, listening for the sound of their feet. He'd half-expected another encounter with the Mother's granddaughter.

They tried to outmaneuver him; he stepped back to his former spot, catching his breath and digging frantically for his knife. It came out, just as they realized he'd tricked them.

Sheila was still on her knees, fumbling with something, and apparently paying no attention to him. But now she jerked to her feet, her hand going back and forward.

It was a six-inch section of pipe, with a thin wisp of smoke, and the throw was toward Gordon's feet. The hoodlums yelled, and ducked, while Sheila broke into a run away from him. The little homemade bomb landed, bounced, and lay still, with its fuse almost burned down.

Gordon's heart froze in his throat, but he was already in action. He spat savagely into his hand, and jumped for the bomb. If the fuse was powder-soaked, he had no chance. He brought his palm down against it, and heard a faint hissing. Then he held his breath, waiting.

No explosion came. It had been a crude job, with only a wick for a fuse.

Sheila Corey had stopped at a safe distance; now she grabbed at her helpers, and swung them with her. The three came back, Sheila in the lead with her knife flashing.

Gordon side-stepped her rush, and met the other two head-on, his knife swinging back. His foot hit some of the rubble on the ground at the last second, and he skidded. The leading mobster saw the chance and jumped for him. Gordon bent his head sharply, and dropped, falling onto his shoulders and somersaulting over. He twisted at the last second, jerking his arms down to come up facing the other.

Then a new voice cut into the fracas, and there was the sound of something landing against a skull with a hollow thud. Gordon got his head up just in time to see a man in police uniform kick aside the first hoodlum and lunge for the other. There was a confused flurry; then the second went up into the air and came down in the newcomer's hands, to land with a sickening jar and lie still. Behind, Sheila Corey lay crumpled in a heap, clutching one wrist in the other hand and crying silently.

Bruce Gordon came to his feet and started for her. She saw him coming, cast a single glance at the knife that had been knocked from her hands, then sprang aside and darted back through the parked trucks. In the street, she could lose herself in the swarm of Nick's Croopsters; Gordon turned back.
