As she passed da Silva, he looked up at her groggily. In his expression there was still the ghost of desire.

"You jerk," she said to him and walked on and went down the stairs.

Phil felt his heart hammering ten, eleven, twelve times, like a clock striking, and then he was racing downstairs and someone was pounding along after him.

He caromed off the open front door and stumbled down the steps in time to see a dark car roar off. Greeley was beside him now, barking orders into a pocket radio. From the other end of the street, another car shot in. Red plumes shot forward from under its hood as it rocket-braked to a heaving stop. Greeley piled into the back seat. Phil scrambled in after him.

"You can still see them," Greeley yelled at the driver. "Take all chances. Rockets!" Then he turned to Phil. "Who are you?"

"Phil Gish of the U. S. Newsmoon," Phil replied recklessly, but the last word was lost in the rocket's roar.

The other car had been about five blocks away when they had taken off. As Phil untwisted himself with difficulty from the huddle into which acceleration had thrown him, he saw that its lead had been reduced to almost one block.

"Douse the jets," Greeley ordered. "We can curb them on our regulars; but watch out they don't shift. They may have rockets. Where do you stand in Project Kitty, Gish?"

"Sort of special observer," Phil improvised gaspingly, still hanging on with both hands. "My section has decided the green cat may not be dangerous."

"What?" Greeley demanded, peering ahead.
