They got nowhere. Solidly, the prisoner stuck by his guns. Why had he tried to shoot the Earthmen? He didn't know. What were his orders from Sator? Silence. What were Sator's plans? Silence. Did he know anything of the new weapon? A shrug of the shoulders.

Finally, Arcot spoke to the Chief Investigation Officer. "May I try my luck? I think I'm powerful enough to use a little combination of hypnosis and telepathy that will get the information out of him." The Investigator agreed to try it.

Arcot walked over as if to inspect the prisoner. For an instant, the man looked defiantly at Arcot. Arcot glared back. At the same time, his powerful mind reached out and began to work subtly within the prisoner's brain. Slowly, a helpless, blank expression came over the man's face as his eyes remained fixed on Arcot's own. The man was as helplessly bound mentally as the lux cable bound him physically.

For a full quarter of an hour, the two men, Earthmen and Satorian, stood locked in a frozen tableau, staring into each other's eyes. The onlookers waited in watchful silence.

Finally, Arcot turned and shook his head, as if to clear it. As he did so, the spy slumped forward in his chair, unconscious.

Arcot rubbed his own temples and spoke in English to Morey. "Some job! You'll have to tell them what I found out; my head is splitting! With a headache like this, I can't communicate.

"Torlos was right; they were trying to get rid of all four of us. We're the only ones who can operate the ship, and that ship is the only defense against them.

"He knows several other spies here in the city, and we can, I think, practically wipe out the Satorian spy system all over the planet with the information he gave me and what we can get from others we arrest.

"Unfortunately, he doesn't know anything about the new weapon; the higher-ups aren't telling anyone, not even their own men. I get the idea that only those on board the ships using it will know about it before the attack.

"An attack is planned, and very soon. He didn't know when. We can only lie in readiness and do everything we can to help these people with their work."
