After a long circuit of the stars, we had returned, under the very eyes of Admiral Gugon Kul, to the system of the Sun. A bitter civil war was raging on the four great moons of Jupiter, the unemployed miners there having attacked the robots when relief was cut off. We were unable to penetrate the quarantine. And Mercury was now uninhabited by men, every human being having been slaughtered when the rebellion there was crushed. We landed upon each of the remaining planets, however. We crossed the trails of a dozen fugitives from Earth--and found that each trail had already ended in death. Hope came, at last, when it had been abandoned. The base of the Twelfth Sector Fleet in the solar system had been established on Oberon, outermost moon of Uranus. "Naralek" got permission to land and pitch his ragged little tent beside the vast space port that was covered with the mile-long gray masses of interstellar cruisers as far as the eye could follow its convexity. * * * * * Kel gave passes to some officer in return for permission to show. The genuine feats of Setsi in perceiving secret thoughts drew attention. Other officers came. And at last, escorted by a hundred trim guardsmen in yellow-and-crimson, Gugon Kul himself. The gigantic swart space-commander stopped the show with a bellowed oath, and demanded an instant demonstration of the sandbat's telepathic powers. That was forthcoming. Kel let the Admiral into his little booth, and the soft voice of Setsi began to comment on fantastic gambling at the court on Ledros, on misappropriated funds of the fleet, on bribes accepted from Malgarth for a promise to turn the entire fleet over to the Corporation. The Admiral turned very purple, and stalked out of the booth. He returned hastily to his flagship; and his guardsmen came back to seize the _Chimerian Bird_ and arrest us all, on suspicion of espionage. They were one minute too late. Their disruptor guns flamed in vain against the departing hull of our craft. For Setsi, the instant of Gugon Kul's departure, had warbled out a warning, and then the clue we had sought so long. "Danger, Kel! Oh, there's danger, and a dancer. Tedron Du has a dancer. Kel, we're all in danger!" That liquid, throbbing chuckle. "For Setsi told too many secrets of the Admiral. But the Emperor on Ledros has a new dancing girl. And she's in danger, too. For her name is Verel Erin!" VIII ROBOT SIMULACRUM Alarm rocked the space port behind us. Great cruisers lifted ponderously from their cradles. And a thousand little gray patrol boats, fleet as our own tiny ship, rocketed into pursuit. "We're lost!" I gasped. And tall dark Jeron, standing gravely at the controls, shook his head.
