He was still exultantly certain of this as he jerked open the doors of the first three rooms. Each one was empty. And the fourth and fifth, as well. Frantically, he pulled open door after door, going through the motions, although his mind told him that it was useless, that all of the boys, with a Saucer so close, would be out looking at it.

Wait until they returned? He couldn't remain in the dormitory and, even if he did, when they all came back, how could he find out which boys had gone up to the ship? They wouldn't be likely to tell, nor would the others, even if they knew. Aimlessly, he went on opening doors, flashing his Watcher's light.

Perhaps there would be a clue in one of the rooms. Excited again, he rapidly checked them, rummaging in closets, picking up their sports things and their toys. Nothing there. Until he found the book.

It was an odd-looking book, in a language he couldn't read. He looked at it doubtfully. Was the script simply Cyrillic? Or Hebrew? He stuffed it into his pocket and glanced around at the walls of the room. Pictures of athletes, mostly, and a couple of pin-ups. In a drawer, under some clothing, a French post card. He examined some of the objects on the dresser.

Then he was looking stupidly at his hand. He was holding a piece of string with a ring attached to it. And, just as certainly, there was something attached to the other end. Or it had been. But there was nothing he could see now. He pulled on the string and it tightened. Yes, there was a drag on the other end, but there was nothing he could see ... or feel.

He tried to reconstruct his actions. He had been pawing among the things. He had taken hold of the string and had pulled something attached to the end of it off the table. The thing had fallen and disappeared—but where? It was still tied to the string, but where was it?

Another dimension, he thought, feeling the hair stand up on his neck, the sudden riot of his blood as he knew he had found the evidence he wanted.

He snapped off the light and groped his way rapidly down the stairs. Once on the street, he began to run. It did not occur to him to feel ridiculous at dragging along behind him, on the end of a string, some object which he could not see.


"Okay," Ann said. "But what is it?" She sat on the divan looking at the book.
