Simak Weird are the conditions of the interdimensional struggle faced by Dr. White's ninety-nine men. The paper had gone to press, graphically describing the latest of the many horrible events which had been enacted upon the Earth in the last six months. The headlines screamed that Six Corners, a little hamlet in Pennsylvania, had been wiped out by the Horror. Another front-page story told of a Terror in the Amazon Valley which had sent the natives down the river in babbling fear. Other stories told of deaths here and there, all attributable to the "Black Horror," as it was called. The telephone rang. "Hello," said the editor. "London calling," came the voice of the operator. "All right," replied the editor. He recognized the voice of Terry Masters, special correspondent. His voice came clearly over the transatlantic telephone. "The Horror is attacking London in force," he said. "There are thousands of them and they have completely surrounded the city. All roads are blocked. The government declared the city under martial rule a quarter of an hour ago and efforts are being made to prepare for resistance against the enemy." "Just a second," the editor shouted into the transmitter. He touched a button on his desk and in a moment an answering buzz told him he was in communication with the press-room. "Stop the presses!" he yelled into the speaking tube. "Get ready for a new front make-up!" "O.K.," came faintly through the tube, and the editor turned back to the phone. "Now let's have it," he said, and the voice at the London end of the wire droned on, telling the story that in another half hour was read by a world which shuddered in cold fear even as it scanned the glaring headlines. * * * * * "Woods," said the editor of the _Press_ to a reporter, "run over and talk to Dr. Silas White. He phoned me to send someone. Something about this Horror business." Henry Woods rose from his chair without a word and walked from the office. As he passed the wire machine it was tapping out, with a maddeningly methodical slowness, the story of the fall of London. Only half an hour before it had rapped forth the flashes concerning the attack on Paris and Berlin. He passed out of the building into a street that was swarming with terrified humanity. Six months of terror, of numerous mysterious deaths, of villages blotted out, had set the world on edge. Now with London in possession of the Horror and Paris and Berlin fighting hopelessly for their lives, the entire population of the world was half insane with fright.
