and the opening was revealed by a sliding panel. Without hesitation, she tossed in the capsule of G-Agent. Dimly, she remembered how she had collected it, painfully over a period of months, drop by drop and stored it in the special non-corrosive alloy of the container. She had access to all of Daddy's laboratory equipment. The container would explode in half an hour. Thirty minutes to get outside the buildings and over to the pits and the lethal rocket. She felt nothing but a kind of depersonalized tension of responsibility as she removed her hat and took the small deadly neutron beam gun from the tiny sling she had fixed inside.

She held the gun to her left side and ran in nakedness and silence down the glowing tube. An overweight guard in his brown UN uniform eased around the curve in the tube and stood with his back to her. It was a good place for him to walk what was to him a useless beat. There was nothing to guard against but boredom. This was the
