Craven grimaced. "I can guess. Those boys didn't stop with just finding how to harness material energy. They probably have more things than you can even suspect. They were working with force fields, you remember, when they stumbled onto the energy. Force fields are something we don't know much about. A man monkeying around with them is apt to find almost anything."
"What are you getting at?"
"My guess would be that they have a new kind of television working in the fourth dimension, using time as a factor. It would penetrate anything. Nothing could stop it. It could go anywhere, at a speed many times the speed of light ... almost instantaneously."
Chambers sat upright in his chair. "Are you sure about this?"
Craven shook his head. "Just a guess. I tried to figure out what I would do if I were Page and Manning and had the things they had. That's all."
"And what would you do?"
Craven smiled dourly. "I'd be using that television right in this office," he said. "I'd keep you and me under observation all the time. If what I think is true, Manning is watching us now and has heard every word we said."
Chambers' face was a harsh mask of anger. "I don't believe it could be done!"
"Doctor Craven is right," said a quiet voice.
Chambers swung around in his chair and gasped. Greg Manning stood inside the room, just in front of the desk.
