The thin moaning that went up from them was more horrible than any cry of agony. "The Invaders are here, citizens," the commentator was saying in a strangled voice. "Stay off the streets. Hide yourselves. Stay off the streets...." His voice droned on, but neither of them heard it. "Peter!" she said faintly. "Why do they broadcast such things?" "They have to," he told her grimly.
