Time and again, and overtime continued which position his brother now held. Simple, fast, effective, and foolproof! Gentry-Glanf's pseudopod, disguised as a human finger, released the activating distorter! In the laboratory rose- a loud whine and a light flashed reminiscent of a super-nova as Glanf and the time-binding machine disappeared. *** Shading his eyes with one hand, Professor phoenix Karloff looked up from his vivisection of a Syrian aqua-aardvark and said to Adam Rink, the Android: "Bless my garters, what won't that young fool think of next?" *** Transported instantaneously to the day of his birth, Glanf materialized on the front steps of the hospital, slipped inside, overpowered a lone intern with his portable thalamic-paralyzer, donned the white uniform, walked boldly into the baby ward, went directly over to himself-the infant, removed himself from one crib and substituted his twin brother for himself, putting himself in his brother's bed. Then, cackling mirthfully to himself-as-adult in Saturnian pidgeon-Martian, he reactivated the nuclear stud and before you could say "Wow" he reappeared in the laboratory just as Professor Karloff was ending the speech: “that young fool think of next?" At that instant his smile of confidence froze. Why had he returned to the laboratory, if he were the King of the Galaxy? How come he was still an insignificant interstellar spy? Why was he not in the Uranium Chair of the King? What had gone wrong? Where was the mixup? Why . . . I'll tell you why!" shouted Adam the Android (who was also a telepath), tearing off his human face and revealing the lizard-like features of the terrible man-eating Plutonian Quaggle-beast: “Because I am really your twin brother and I perfected the time-binding machine just twenty minutes before you did, and I went to our birthplace and switched the babies first, so you actually put yourself back to where you were in the first place!" Then laughing like a moon-mad space pirate, the android-human-Quaggle-beast slid across the floor on his nineteen appendages into a teleportation booth, appearing immediately in his Uranium Chair at the meeting of the Galactic Council, where he quickly signed a document recommending death for his twin brother, Professor Aych Gentry, who was really Rork Glanf. But Glanf the Ganymedian was not so easily defeated. Instantly he pressed the stub of the tensor force-field machine and returned to the past two hours before the preceeding conversation occurred. There he perfected the Time Machine, and returned to the present one-half hour before his twin brother had perfected it, then rapidly returned to the day of his birth, overpowered the intern, 118 switched the babies, and reappeared in the laboratory just as Professor Karloff was ending the speech: “that young fool think of next?" *** At that instant his smile of confidence froze. Why had he returned to the laboratory, if he were King of the Galaxy?. How come he was still an insignificant inter-stellar spy? Why was he not in the Uranium Chair of the King? What had gone wrong? Where was the mixup? Why . . . "l'll tell you why!" howled Adam the Android (also a telepath), tearing off his human face and revealing the ugly features of the truculent flesh-eating Plutonian Quaggle-beast. "Because I, Adam, l am really your twin brother and I knew you were going to go back in time two hours before I perfected the Time Machine so I went back four hours before you went back the second time and then I returned to our birthplace and switched the babies before you switched the babies the second time after you had switched the babies the first time, so you actually put yourself back to where you were the time before you switched the babies the second time!" Then shrieking like an insane spider the human-android-Quaggle-beast slushed across the floor on his nineteen tentacles into a teleportation booth, appearing immediately in the Uranium Chair at the meeting of the Galactic Council, where he signed a death warrant for his twin brother, Professor Gentry, who was really Rork Glanf. But the spy-Professor-Ganymedian was not so easily defeated. Instantly he pressed the stub of the time binding machine and returned to the past, six hours before the two preceding occurrences, perfected the Time Machine, returned to the present one-half hour before his twin brother had perfected it the second time, went back to the day of his birth, overpowered the intern, switched the babies, and reappeared in the laboratory just as Professor Karloff was ending his speech: “that young fool think of next?" *** But his smile of confidence froze. Why had he returned to the laboratory, if he were King of the Galaxy? What had gone Wrong? Where was the mixup? Why . . . "l'll tell you why!" screamed Adam the Android (who could also read minds), tearing off his face and so on: Because l am really your twin brother and I knew you were going to go and so on and on . . ." *** Those two little babies really got around, hey? *** P. S. You rascals looking for the part about Earth-Girl shown in opening illustration-never mind! It was all a hoax by us foxy editors to make you read story.
