And then he shot them both with gun number two. No needle charges this time; such shots would have blown them both in two, unprotected as they were by spacesuits. The small handgun merely jangled their nerves with a high-powered blast of accurately beamed supersonics. While they were still twitching, he went over and jabbed them with a drug needle. Then he went on into the hideout. He had to knock out one more man, whom he found sound asleep in a room off the short corridor. It took a gas bomb to get the two women who were guarding the kid. He made sure that the BenChaim boy was all right, then he went to the little communications room and called for help. IX Colonel Walther Mannheim tapped the map that glowed on the wall before him. "He's right there, where those tunnels come together." Bart Stanton looked at the map of Manhattan Island and at the gleaming colored traceries that threaded their various ways across it. "Just what was the purpose of those tunnels?" he asked curiously. "They were for rail transportation," said the colonel. "The island was hit by a sun bomb during the Holocaust, and almost completely leveled and slagged down. When the city was rebuilt, there was naturally no need for such things, so they were simply sealed off and forgotten." "Right under Government City," Stanton said. "Incredible." "It used to be one of the largest seaports in the world," Colonel Mannheim said, "and it probably still would be if the inertia drive hadn't made air travel cheaper and easier than seagoing." "How did he find out about the tunnels?" Stanton asked. The colonel pointed at the north end of the island. "After the Holocaust, the first returnees to the island were wild animals which crossed from the mainland from the north. The Harlem River isn't very wide at this point. Also, because of the rocky hills at this end of the island, there were places which were spared the direct effects of the bomb, and grasses and trees began growing there. That's why it was decided to leave that section as a game preserve when the Government built the capital on the southern part of the island." His finger moved down the map. "The upper three miles of the island, down to here, where it begins to widen, are all game preserve. There's a high wall here which separates it from the city, and the ruins of the bridges which connected with the mainland have been removed, so the animals can't get back across any more. "Two years after he arrived, the Nipe was almost caught. He had managed, somehow--we're not sure yet exactly how--to get here from Asia. According to the psychologists who have been studying him, he apparently does not believe that human beings are any more than trained animals; he was looking then--as he is apparently still looking--for the 'real' rulers of Earth. He expected to find them, of course, in Government City. Needless to say," said the colonel with a touch of irony, "he failed." "But he was seen?" asked Stanton.
