"Are you trying to make a fool of me?" The fat man was getting angry.

His voice was rising.

"Shhh," Brett cautioned. "You"ll attract the Gels."

"Blast the Jilts, whatever that is!" the fat man snapped. "Now, get along with you. I"ll call the manager."

"Don"t you know?" Brett said, staring at the fat man. "They"re all dummies; golems, they"re called. They"re not real."

"Who"re not real?"

"All these imitation people at the tables and on the dance floor. Surely you realize--"

"I realize you"re in need of medical attention." The fat man pushed back his chair and got to his feet. "You keep the table," he said. "I"ll dine elsewhere."

"Wait!" Brett got up, seized the fat man"s arm.

"Take your hands off me--" The fat man went toward the door. Brett followed. At the cashier"s desk Brett turned suddenly, saw a fluid brown shape flicker--

"Look!" He pulled at the fat man"s arm--

"Look at what?" The Gel was gone.

"It was there: a Gel."

The fat man flung down a bill, hurried away. Brett fumbled out a ten, waited for change. "Wait!" he called. He heard the fat man"s feet receding down the stairs.

"Hurry," he said to the cashier. The woman sat gla.s.sy-eyed, staring at nothing. The music died. The lights flickered, went off. In the gloom Brett saw a fluid shape rise up--

He ran, pounding down the stairs. The fat man was just rounding the corner. Brett opened his mouth to call--and went rigid, as a translucent shape of mud shot from the door, rose up to tower before him. Brett stood, mouth half open, eyes staring, leaning forward with hands outflung. The Gel loomed, its surface flickering--waiting. Brett caught an acrid odor of geraniums.

A minute pa.s.sed. Brett"s cheek itched. He fought a desire to blink, to swallow--to turn and run. The high sun beat down on the silent street, the still window displays.

Then the Gel broke form, slumped, flashed away. Brett tottered back against the wall, let his breath out in a harsh sigh.

Across the street he saw a window with a display of camping equipment, portable stoves, boots, rifles. He crossed the street, tried the door.

It was locked. He looked up and down the street. There was no one in sight. He kicked in the gla.s.s beside the latch, reached through and turned the k.n.o.b. Inside he looked over the shelves, selected a heavy coil of nylon rope, a sheath knife, a canteen. He examined a Winchester repeating rifle with a telescopic sight, then put it back and strapped on a .22 revolver. He emptied two boxes of long rifle cartridges into his pocket, then loaded the pistol. He coiled the rope over his shoulder and went back out into the empty street.

The fat man was standing in front of a shop in the next block, picking at a blemish on his chin and eyeing the window display. He looked up with a frown, started away as Brett came up.

"Wait a minute," Brett called. "Didn"t you see the Gel? the one that cornered me back there?"

The fat man looked back suspiciously, kept going.

"Wait!" Brett caught his arm. "I know you"re real. I"ve seen you belch and sweat and scratch. You"re the only one I can call on--and I need help. My friend is trapped--"

The fat man pulled away, his face flushed an even deeper red. "I"m warning you, you maniac: get away from me...!"

Brett stepped close, rammed the fat man hard in the ribs. He sank to his knees, gasping. The panama hat rolled away. Brett grabbed his arm, steadied him.

"Sorry," he said. "I had to be sure. You"re real, all right. We"ve got to rescue my friend, Dhuva--"

The fat man leaned against the gla.s.s, rolling terrified eyes, rubbing his stomach. "I"ll call the police!" he gasped.

"What police?" Brett waved an arm. "Look. Not a car in sight. Did you ever see the street that empty before?"

"Wednesday afternoon," the fat man gasped.

"Come with me. I want to show you. It"s all hollow. There"s nothing behind these walls--"

"Why doesn"t somebody come along?" the fat man moaned.

"The masonry is only a quarter-inch thick," Brett said. "Come on; I"ll show you."

"I don"t like it," said the fat man. His face was pale and moist.

"You"re mad. What"s wrong? It"s so quiet ..."

"We"ve got to try to save him. The Gel took him down into this pit--"

"Let me go," the man whined. "I"m afraid. Can"t you just let me lead my life in peace?"

"Don"t you understand? The Gel took a man. They may be after you next."

"There"s no one after me! I"m a business man ... a respectable citizen.

I mind my own business, give to charity, go to church. All I want is to be left alone!"

Brett dropped his hands from the fat man"s arms, stood looking at him: the blotched face, pale now, the damp forehead, the quivering jowls. The fat man stooped for his hat, slapped it against his leg, clamped it on his head.

"I think I understand now," said Brett. "This is your place, this imitation city. Everything"s faked to fit your needs--like in the hotel.

Wherever you go, the scene unrolls in front of you. You never see the Gels, never discover the secret of the golems--because you conform. You never do the unexpected."

"That"s right. I"m law-abiding. I"m respectable. I don"t pry. I don"t nose into other people"s business. Why should I? Just let me alone ..."

"Sure," Brett said. "Even if I dragged you down there and showed you, you wouldn"t believe it. But you"re not in the scene now. I"ve taken you out of it--"

Suddenly the fat man turned and ran a few yards, then looked back to see whether Brett was pursuing him. He shook a round fist.

"I"ve seen your kind before," he shouted. "Troublemakers."

Brett took a step toward him. The fat man yelped and ran another fifty feet, his coat tails bobbing. He looked back, stopped, a fat figure alone in the empty sunny street.

"You haven"t seen the last of me!" he shouted. "We know how to deal with your kind." He tugged at his vest, went off along the sidewalk. Brett watched him go, then started back toward the hollow building.
