"Get the de-energizer."

"We can't proceed until — "

The men came toward Ed, moving around him. One lugged a long hose with some sort of nozzle. A portable cart came wheeling up. Instructions were rapidly shouted.

Ed broke out of his paralysis. Fear swept over him. Panic. Something hideous was happening. He had to get out. Warn people. Get away.

He turned and ran, back down the stairs. The stairs collapsed under him. He fell half a flight, rolling in heaps of dry ash. He got to his feet and hurried on, down to the ground floor.

The lobby was lost in the clouds of gray ash. He pushed blindly through, toward the door. Behind him, the white-clad men were coming, dragging their equipment and shouting to each other, hurrying quickly after him.

He reached the sidewalk. Behind him the office building wavered and sagged, sinking to one side, torrents of ash raining down in heaps. He raced toward the corner, the men just behind him. Gray cloud swirled around him. He groped his way across the street, hands outstretched. He gained the opposite curb —

The sun winked on. Warm yellow sunlight streamed down on him. Cars honked. Traffic lights changed. On all sides men and women in bright spring clothes hurried and pushed: shoppers, a blue-clad cop, salesmen with briefcases. Stores, windows, signs. . noisy cars moving up and down the street. .

And oyerhead was the bright sun and familiar blue sky.

Ed halted, gasping for breath. He turned and looked back the way he had come. Across the street was the office building — as it had always been. Firm and distinct. Concrete and glass and steel.
