The window at the end of the corridor had reappeared as the safety shutter slid back. Through it, tantalizingly small and far away, Price watched the landing of a starship, and it was disappointingly remote and unreal as a scene done with models for an old film. Until he felt the mighty fabric of the Citadel, man-made mountain of steel and iron, quiver underneath him with the shock-wave of that landing. Then he knew. The voice stopped speaking. There was a moment of dead quiet, as though what the voice had said was more momentous than the alarm. Linna's face was pale again, and the guards looked both excited and apprehensive. One of them spoke to Linna, and she shook her head, apparently giving him a reassuring answer. Price said irritably, "Can you tell me what's going on?" "There was a skirmish," she said, "out there. That's what the alarm was, to tell us there was fighting going on, but of course it was already over. There was only one Ei ship, a scout." "Oh," said Price, and almost smiled. Scramble them once in a while, keep them on their toes. Remind them of the menace. It was a simple technique. Earthmen had evolved it quite early. People were talking now. He could hear their voices echoing down the metal halls, excited, fearful. Several went to the window to crane their necks at the distant starship. And then the metallic voice began to speak again, very crisp and clipped. "Maximum security," Linna said. "All corridors cleared, all doors and safety bulkheads locked. All off-duty personnel in quarters. Go in, Price." She pointed to his cell door. "I have to hurry." The corridor was clearing like magic. Price hung obstinately in the doorway. "What now?" "They captured the scout. They're bringing in two of the Ei--alive." One of the guards shoved him in, and the door slammed shut on its magnetic lock. Price lay down on the bunk. So they had captured a scout, and they were bringing in two Ei, alive. And everybody in the Citadel was ordered behind locked doors. Handy. Very. He was beginning to feel less hostility toward at least some of the Vurna. They were not so hard-headed and skeptical as the Earthmen. They believed, and the belief was keeping them here to man an outpost fort when they would doubtless much rather return home.
