Astounding Stories of Super-Science, August 1930

If, therefore, Dalis could mask his own thoughts from the brains of men, he could also mask the thoughts of the people of his Gens, merely by willing it! So Sarka and his father and Jaska could not know whether the Gens of Dalis had gone over in a body with him, in a truce with the people of the Moon, or whether they were dual prisoners--of Dalis and of the Moon-men! More than ever was it necessary for someone to somehow reach the Moon and make a thorough investigation, discover just what Dalis was doing, what mischief he was hatching. The secret exit dome seemed to be the answer. "You can manage without me, father?" asked Sarka. The elder Sarka nodded. "Of the other Spokesmen of Earth," went on Sarka, "I trust Gerd the most. Might I suggest that you bring him here, trust him in all details, and let him take my place wherever possible? Or, better still, keep Jaska here with you! I ... I may not be able to return! I'll try to find a way, but--we can always communicate telepathically. Jaska...." "Jaska," said that young lady grimly, "goes with Sarka wherever Sarka goes!" "But it may mean death! We can only guess at the cunning of the Moon dwellers! They may have been in secret communication with Dalis for centuries! Dalis, who somehow discovered our secret finger code, may also know of the secret exit dome, and the principle upon which it operates! If he does, he may know how to combat it! Perhaps that explains his laughter! Perhaps he heard and understood every word we spoke, hears and understands every word we speak now! Who knows? He may wait until I have passed through the secret exit dome, and then make it impossible for me to be reincarnated on the Moon--or elsewhere!"
