telescopic lens of the TV camera showed the blood spilling from his open mouth--there was no other motion. Then the camera picked up the figure of the Priman as he popped into view from inside the building. There was a moment of shocked silence inside the spaceship. Then three things happened at once. Somebody snarled, "Get that rat!" There was a flash from a high-powered rifle and the resultant explosion of the bullet against the front of the UN building, too high to do any damage. There was the leap of the startled Priman backward through the door. Grimes jumped to the communication panel and grabbed a handset. "Stop that firing. Fall in for inspection of firearms immediately.

Now listen to me. Get everybody out of the UN building. What we're looking for must be right there. That may not be the only place, but it'll do for a starter." "I will have the building vacated, Captain.
