Full turned to his wife and began to mutter to her.

Villa said, "I don't like crooks, I run a respectable stand and I am an honest man," and scratching his hand where the healed burn was, he turned away likewise. Summersby was sitting on the tire, and only Adam looked sympathetic. The boy wasn't crooked, that was plain, but Watkins had the glamor that a big-time thief has for the young, the fake aura of Robin-Hoodism.

He shook his head. He'd had to spill it. For a while they'd trusted him and now he was a pariah.

The food panel opened and something plumped in. Watkins glanced at his chronograph. Ten o'clock Saturday. He went over to the food.

It was a big, glossy chocolate-brown vulture with a blue head.

"Well," said Adam. "Well, now, I don't know."

"They pulled a boner this time," said Watkins. "Unless it's part of the conditioning."

Villa picked it up. "It weighs many pounds. It's warm, just killed. I don't want any of it." He dropped it on the straw. "With my spices, perhaps; but not cooked on that grill, without sauce and spice. Aargh!"

Watkins thought, Amen to that. He rubbed the sandy bristles on his chin. No razor or soap here. It dawned on him that he was thirsty, and he went to the fountain. As it always did when he bent over to drink, the curious web of silver strands in the corner caught his eye. There were so many puzzles about this damned lab that he despaired of ever solving all of them.

After fifteen minutes, the wall opened. They went out, Villa carrying the vulture. He flung it at the feet of the chief scientist, who was there with two associates.
