Llewellyn was the first to break the silence. He darted to the nearest sales-robot, made some practiced manipulations, and then there was a clinking and he was waving a green and silver handful and his teeth and the whites of his eyes shone gleefully in his black face.

"They're still carrying the day's cash!" he called softly.

Buck looked from the money army to the glamor army with greedy indecision. When Carstairs snorted contemptuously, he trotted over to help Llewellyn, who was methodically working his way down the first row of sales-robots.

Despite his show of greater self control, it was obvious that Carstairs' hands were itching too. He looked at Phil uncertainly. Then, "Wake up, Mitz," he commanded sharply. She obediently turned toward him an oddly incurious face. "Mitz," he went on, "I want you to guard the clown. If he tries to get away or goes for any buttons, use your shiv on him." She nodded.

"Hey," Buck called in an excited stage whisper, "I think we're coming to some that are gambling robots."

But Carstairs didn't go at once, although he was noiselessly snapping his fingers in an excess of impatience. He studied Mitzie fiercely. "You get it, Mitz? I don't want any slip-ups. You made one already today. Not that I believe for a minute you're soft on the clown, but you've acted a bit silly around him. There mustn't be any more of that. Understand?"

This time her nod, though mute as the first, seemed to satisfy him and he rushed off to join Llewellyn and Buck.

At the same instant Phil quietly turned around and walked through an archway just beside the one through which they had entered the big room. He hadn't taken ten steps down the curving corridor before Mitzie had whirled past him and poised herself squarely in his path.

"Get back," she whispered. The hand directing the ten-inch knife at Phil's chest didn't waver enough to make the frosty highlights on it flicker.

Phil smiled at her. "Mitzie," he said gently, "your friends have found what they came for, but I haven't. You're going to let me go past."
