"Three generations ago, a man couldn't have held a finger over that flame for more than a tenth part of that count. Doesn't all this prove something to you?"

The 'copter was hovering above Alcala's house. Camba lowered it to the ground and opened the door before answering. "It proves only that a good and worthy man will cut and burn his hand for an unworthy friendship. Good night."

Disconcerted, Alcala watched the 'copter lift away into the night, then, turning, saw that the lights were still on in the laboratory. Camba might have deduced something from that, if he knew that Nita and the girl were not supposed to be home.

Alcala hurried in.

Johnny hadn't left yet. He was sitting at Alcala's desk with his feet on the wastebasket, the way Alcala often liked to sit, reading a technical journal. He looked up, smiling. For a moment Alcala saw him with the new clarity of a stranger. The lean, weathered face; brown eyes with smile deltas at the corners; wide shoulders; steady, big hands holding the magazine—solid, able, and ruthless enough to see what had to be done, and do it.

"I was waiting for you, Ric."

"The Feds are after you." Ricardo Alcala had been running. He found he was panting and his heart was pounding.

Delgados' smile did not change. "It's all right, Ric. Everything's done. I can leave any time now." He indicated a square metal box standing in a corner. "There's the stuff."

What stuff? The product Johnny had been working on? "You haven't time for that now, Johnny. You can't sell it. They'd watch for anyone of your description selling chemicals. Let me loan you some money."

"Thanks." Johnny was smiling oddly. "Everything's set. I won't need it. How close are they to finding me?"
