"We may be watched,” warned Stutsman.
The mobster started from his chair, his eyes darting about the room.
Stutsman grunted disgustedly. “If we're watched, there isn't anything we can do about it."
"We can't, huh?” snarled the gangster. “Why not?"
"Because the watcher is on the West Coast. We can't reach him. If he's watching, he can see every move we make, hear every word we say."
"Who is it?"
"GREG Manning or Russ Page,” said Stutsman. “You've heard of them?"
"Sure. I heard of them."
"They have a new kind of television,” said Stutsman. “They can see and hear everything that's happening on Earth, perhaps in all the Solar System. But I don't think they're watching us now. Craven has a machine that can detect their televisor. It registers certain field effects they use. They weren't watching when I left Craven's laboratory just a few minutes ago. They may have picked me up since, but I don't think so."
"So Craven has made a detector,” said Greg calmly. “He can tell when we're watching now."
