"It should take about fifteen minutes for the fire to burn through the rope," Brett said. "Then the wagon will fall and dump the hot coals in the gasoline. By then it will have spread all over the surface and flowed down side tunnels into other parts of the cavern system."

"But it may not get them all."

"It will get some of them. It"s the best we can do right now. You get the fire going in the wagon; I"ll start this one up."

Dhuva sniffed the air. "That fluid," he said. "We know it in Wavly as phlogistoneum. The wealthy use it for cooking."

"We"ll use it to cook Gels." Brett struck a match. The fire leaped up, smoking. Dhuva watched, struck his match awkwardly, started his blaze.

They stood for a moment watching. The nylon curled and blackened, melting in the heat.

"We"d better get moving," Brett said. "It doesn"t look as though it will last fifteen minutes."

They stepped out into the street. Behind them wisps of smoke curled from the door. Dhuva seized Brett"s arm. "Look!"

Half a block away the fat man in the panama hat strode toward them at the head of a group of men in grey flannel. "That"s him!" the fat man shouted, "the one I told you about. I knew the scoundrel would be back!"

He slowed, eyeing Brett and Dhuva warily.

"You"d better get away from here, fast!" Brett called. "There"ll be an explosion in a few minutes--"

"Smoke!" the fat man yelped. "Fire! They"ve set fire to the city! There it is! pouring out of the window ... and the door!" He started forward.

Brett yanked the pistol from the holster, thumbed back the hammer.

"Stop right there!" he barked. "For your own good I"m telling you to run. I don"t care about that crowd of golems you"ve collected, but I"d hate to see a real human get hurt--even a cowardly one like you."

"These are honest citizens," the fat man gasped, standing, staring at the gun. "You won"t get away with this. We all know you. You"ll be dealt with ..."

"We"re going now. And you"re going too."

"You can"t kill us all," the fat man said. He licked his lips. "We won"t let you destroy our city."

As the fat man turned to exhort his followers Brett fired, once twice, three times. Three golems fell on their faces. The fat man whirled.

"Devil!" he shrieked. "A killer is abroad!" He charged, mouth open.

Brett ducked aside, tripped the fat man. He fell heavily, slamming his face against the pavement. The golems surged forward. Brett and Dhuva slammed punches to the sternum, took clumsy blows on the shoulder, back, chest. Golems fell. Brett ducked a wild swing, toppled his attacker, turned to see Dhuva deal with the last of the dummies. The fat man sat in the street, dabbing at his bleeding nose, the panama still in place.

"Get up," Brett commanded. "There"s no time left."

"You"ve killed them. Killed them all ..." The fat man got to his feet, then turned suddenly and plunged for the door from which a cloud of smoke poured. Brett hauled him back. He and Dhuva started off, dragging the struggling man between them. They had gone a block when their prisoner, with a sudden frantic jerk, freed himself, set off at a run for the fire.

"Let him go!" Dhuva cried. "It"s too late to go back!"

The fat man leaped fallen golems, wrestled with the door, disappeared into the smoke. Brett and Dhuva sprinted for the corner. As they rounded it a tremendous blast shook the street. The pavement before them quivered, opened in a wide crack. A ten-foot section dropped from view.

They skirted the gaping hole, dashed for safety as the facades along the street cracked, fell in clouds of dust. The street trembled under a second explosion. Cracks opened, dust rising in puffs from the long wavering lines. Masonry collapsed around them. They put their heads down and ran.

Winded, Brett and Dhuva walked through the empty streets of the city.

Behind them, smoke blackened the sky. Embers floated down around them.

The odor of burning Gel was carried on the wind. The late sun shone on the blank pavement. A lone golem in a ta.s.seled fez, left over from the morning"s parade, leaned stiffly against a lamp post, eyes blank. Empty cars sat in driveways. TV antennae stood forlornly against the sunset.

"That place looks lived-in," said Brett, indicating an open apartment window with a curtain billowing above a potted geranium. "I"ll take a look."

He came back shaking his head. "They were all in the TV room. They looked so natural at first; I mean, they didn"t look up or anything when I walked in. I turned the set off. The electricity is still working anyway. Wonder how long it will last?"

They turned down a residential street. Underfoot the pavement trembled at a distant blast. They skirted a crack, kept going. Occasional golems stood in awkward poses or lay across sidewalks. One, clad in black, tilted awkwardly in a gothic entry of fretted stone work. "I guess there won"t be any church this Sunday," said Brett.

He halted before a brown brick apartment house. An untended hose welled on a patch of sickly lawn. Brett went to the door, stood listening, then went in. Across the room the still figure of a woman sat in a rocker. A curl stirred on her smooth forehead. A flicker of expression seemed to cross the lined face. Brett started forward. "Don"t be afraid. You can come with us--"

He stopped. A flapping window-shade cast restless shadows on the still golem features on which dust was already settling. Brett turned away, shaking his head.

"All of them," he said. "It"s as though they were snipped out of paper.

When the Gels died their dummies died with them."

"Why?" said Dhuva. "What does it all mean?"

"Mean?" said Brett. He shook his head, started off again along the street. "It doesn"t mean anything. It"s just the way things are."

Brett sat in a deserted Cadillac, tuning the radio.

"... anybody hear me?" said a plaintive voice from the speaker. "This is Ab Gullorian, at the Twin Spires. Looks like I"m the only one left alive. Can anybody hear me?"

Brett tuned. "... been asking the wrong questions ... looking for the Final Fact. Now these are strange matters, brothers. But if a flower blooms, what man shall ask why? What lore do we seek in a symphony...?"

He twisted the k.n.o.b again. "... Kansas City. Not more than half a dozen of us. And the dead! Piled all over the place. But it"s a funny thing: Doc Potter started to do an autopsy--"

Brett turned the k.n.o.b. "... CQ, CQ, CQ. This is Hollip Quate, calling CQ, CQ. There"s been a disaster here at Port Wanderl.u.s.t. We need--"

"Take Jesus into your hearts," another station urged.

"... to base," the radio said faintly, with much crackling. "Lunar Observatory to base. Come in, Lunar Control. This is Commander McVee of the Lunar Detachment, sole survivor--"

"... h.e.l.lo, Hollip Quate? Hollip Quate? This is Kansas City calling.

Say, where did you say you were calling from...?"

"It looks as though both of us had a lot of mistaken ideas about the world outside," said Brett. "Most of these stations sound as though they might as well be coming from Mars."

"I don"t understand where the voices come from," Dhuva said. "But all the places they name are strange to me ... except the Twin Spires."

"I"ve heard of Kansas City," Brett said, "but none of the other ones."

The ground trembled. A low rumble rolled. "Another one," Brett said. He switched off the radio, tried the starter. It groaned, turned over. The engine caught, sputtered, then ran smoothly.

"Get in, Dhuva. We might as well ride. Which way do we go to get out of this place?"
