It didn't seem possible. What he saw descending from the black chasm weren't men. They were alien--from some other world, some other dimension. Sliding through this slit, this break in the sh.e.l.l of the universe. Entering through this gap, winged insects from another realm of being.

On the steps of the City Hall a group of men broke up. A few moved toward a waiting car. One of the remaining shapes started to re-enter the City Hall. It changed its mind and turned to follow the others.

Loyce closed his eyes in horror. His senses reeled. He hung on tight, clutching at the sagging fence. The shape, the man-shape, had abruptly fluttered up and flapped after the others. It flew to the sidewalk and came to rest among them.

Pseudo-men. Imitation men. Insects with ability to disguise themselves as men. Like other insects familiar to Earth. Protective coloration.

Mimicry.

Loyce pulled himself away. He got slowly to his feet. It was night. The alley was totally dark. But maybe they could see in the dark. Maybe darkness made no difference to them.

He left the alley cautiously and moved out onto the street. Men and women flowed past, but not so many, now. At the bus-stops stood waiting groups. A huge bus lumbered along the street, its lights flashing in the evening gloom.

Loyce moved forward. He pushed his way among those waiting and when the bus halted he boarded it and took a seat in the rear, by the door. A moment later the bus moved into life and rumbled down the street.

Loyce relaxed a little. He studied the people around him. Dulled, tired faces. People going home from work. Quite ordinary faces. None of them paid any attention to him. All sat quietly, sunk down in their seats, jiggling with the motion of the bus.

The man sitting next to him unfolded a newspaper. He began to read the sports section, his lips moving. An ordinary man. Blue suit. Tie. A businessman, or a salesman. On his way home to his wife and family.

Across the aisle a young woman, perhaps twenty. Dark eyes and hair, a package on her lap. Nylons and heels. Red coat and white angora sweater.

Gazing absently ahead of her.

A high school boy in jeans and black jacket.

A great triple-chinned woman with an immense shopping bag loaded with packages and parcels. Her thick face dim with weariness.

Ordinary people. The kind that rode the bus every evening. Going home to their families. To dinner.

Going home--with their minds dead. Controlled, filmed over with the mask of an alien being that had appeared and taken possession of them, their town, their lives. Himself, too. Except that he happened to be deep in his cellar instead of in the store. Somehow, he had been overlooked.

They had missed him. Their control wasn't perfect, foolproof.

Maybe there were others.

Hope flickered in Loyce. They weren't omnipotent. They had made a mistake, not got control of him. Their net, their field of control, had pa.s.sed over him. He had emerged from his cellar as he had gone down.

Apparently their power-zone was limited.

A few seats down the aisle a man was watching him. Loyce broke off his chain of thought. A slender man, with dark hair and a small mustache.

Well-dressed, brown suit and shiny shoes. A book between his small hands. He was watching Loyce, studying him intently. He turned quickly away.

Loyce tensed. One of _them_? Or--another they had missed?

The man was watching him again. Small dark eyes, alive and clever.

Shrewd. A man too shrewd for them--or one of the things itself, an alien insect from beyond.

The bus halted. An elderly man got on slowly and dropped his token into the box. He moved down the aisle and took a seat opposite Loyce.

The elderly man caught the sharp-eyed man's gaze. For a split second something pa.s.sed between them.

A look rich with meaning.

Loyce got to his feet. The bus was moving. He ran to the door. One step down into the well. He yanked the emergency door release. The rubber door swung open.

"Hey!" the driver shouted, jamming on the brakes. "What the h.e.l.l--"

Loyce squirmed through. The bus was slowing down. Houses on all sides. A residential district, lawns and tall apartment buildings. Behind him, the bright-eyed man had leaped up. The elderly man was also on his feet.

They were coming after him.

Loyce leaped. He hit the pavement with terrific force and rolled against the curb. Pain lapped over him. Pain and a vast tide of blackness.

Desperately, he fought it off. He struggled to his knees and then slid down again. The bus had stopped. People were getting off.

Loyce groped around. His fingers closed over something. A rock, lying in the gutter. He crawled to his feet, grunting with pain. A shape loomed before him. A man, the bright-eyed man with the book.

Loyce kicked. The man gasped and fell. Loyce brought the rock down. The man screamed and tried to roll away. "_Stop!_ For G.o.d's sake listen--"

He struck again. A hideous crunching sound. The man's voice cut off and dissolved in a bubbling wail. Loyce scrambled up and back. The others were there, now. All around him. He ran, awkwardly, down the sidewalk, up a driveway. None of them followed him. They had stopped and were bending over the inert body of the man with the book, the bright-eyed man who had come after him.

Had he made a mistake?

But it was too late to worry about that. He had to get out--away from them. Out of Pikeville, beyond the crack of darkness, the rent between their world and his.

"Ed!" Janet Loyce backed away nervously. "What is it? What--"

Ed Loyce slammed the door behind him and came into the living room.

"Pull down the shades. Quick."

Janet moved toward the window. "But--"

"Do as I say. Who else is here besides you?"

"n.o.body. Just the twins. They're upstairs in their room. What's happened? You look so strange. Why are you home?"

Ed locked the front door. He prowled around the house, into the kitchen.

From the drawer under the sink he slid out the big butcher knife and ran his finger along it. Sharp. Plenty sharp. He returned to the living room.

"Listen to me," he said. "I don't have much time. They know I escaped and they'll be looking for me."

"Escaped?" Janet's face twisted with bewilderment and fear. "Who?"

"The town has been taken over. They're in control. I've got it pretty well figured out. They started at the top, at the City Hall and police department. What they did with the _real_ humans they--"

"What are you talking about?"

"We've been invaded. From some other universe, some other dimension.

They're insects. Mimicry. And more. Power to control minds. Your mind."
