George Webber sat in the little room, trembling, listening, his eyes wide in the thick, misty darkness. He knew it would be a matter of time now. He couldn't run much farther. He hadn't seen them, true. Oh, they had been very clever, but they thought they were dealing with a fool, and they weren't. He knew they'd been following him; he'd known it for a long time now.

It was just as he had been telling the man downstairs the night before: they were everywhere—your neighbor upstairs, the butcher on the corner, your own son or daughter, maybe even the man you were talking to—everywhere!

And of course he had to warn as many people as he possibly could before they caught him, throttled him off, as they had threatened to if he talked to anyone.

If only the people would listen to him when he told them how cleverly it was all planned, how it would only be a matter of months, maybe only weeks or days before the change would happen, and the world would be quietly, silently taken over by the other people, the different people who could walk through walls and think in impossibly complex channels. And no one would know the difference, because business would go on as usual.

He shivered, sinking down lower on the bed. If only people would listen to him—

It wouldn't be long now. He had heard the stealthy footsteps on the landing below his room some time ago. This was the night they had chosen to make good their threats, to choke off his dangerous voice once and for all. There were footsteps on the stairs now, growing louder.

Wildly he glanced around the room as the steps moved down the hall toward his door. He rushed to the window, threw up the sash and screamed hoarsely to the silent street below: "Look out! They're here, all around us! They're planning to take over! Look out! Look out!"

The door burst open and there were two men moving toward him, grim-faced, dressed in white; tall, strong men with sad faces and strong arms.

One was saying, "Better come quietly, mister. No need to wake up the whole town."
