The Stars Like Dust - By Isaac Asimov Page 0,2

couldn't let them get away with it. First, he would need a light, a real one, not the immovable and unsatisfactory glow of the visiphone. That was no problem. He had a self-powered flashlight in the clothes closet.

For a moment, as he fingered the closet-door controls, he wondered if they had jammed that too. But it moved open naturally, and slid smoothly into its wall socket. Biron nodded to himself. It made sense. There was no reason, particularly, to jam the closet, and they didn't have too much time, anyway.

And then, with the flashlight in his hand, as he was turning away, the entire structure of his theory collapsed in a horrible instant. He stiffened, his abdomen ridging with tension, and held his breath, listening.

For the first time since awakening, he heard the murmuring of the bedroom. He heard the quiet, irregular chuckling conversation it was holding with itself, and recognized the nature of the sound at once.

It was impossible not to recognize it. The sound was "Earth's death rattle." It was the sound that had been invented one thousand years before.

To be exact, it was the sound of a radiation counter, ticking off the charged particles and the hard gamma waves that came its way, the soft clicking electronic surges melting into a low murmur. It was the sound of a counter, counting the only thing it could count-death!

Softly, on tiptoe, Biron backed away. From a distance of six feet he threw the white beam into the recesses of the closet. The counter was there, in the far corner, but seeing it told him nothing.

It had been there ever since his freshman days. Most freshmen from the Outer Worlds bought a counter during their first week on Earth. They were very conscious of Earth's radioactivity then, and felt the need of protection. Usually they were sold again to the next class, but Biron had never disposed of his. He was thankful for that now.

He turned to the desk, where he kept his wrist watch while sleeping. It was there. His hand was shaking a little as he held it up to the flashlight's beam. The watch strap was an interwoven flexible plastic of an almost liquidly smooth whiteness. And it was white. He held it away and tried it at different angles. It was white.

That strap had been another freshman purchase. Hard radiation turned it blue, and blue on Earth was the color of death. It was easy to wander into a path of radiating soil during the day if you were lost or careless. The government fenced off as many patches as it could, and of course no one ever approached the huge areas of death that began several miles outside the city. But the strap was insurance.

If it should ever turn a faint blue, you would show up at the hospital for treatment. There was no argument about it. The compound of which it was made was precisely as sensitive to radiation as you were, and appropriate photoelectric instruments could be used to measure the intensity of the blueness so that the seriousness of the case might be determined quickly.

A bright royal blue was the finish. Just as the color would never change back, neither would you. There was no cure, no chance, no hope. You just waited anywhere from a day to a week, and all the hospital could do was to make final arrangements for cremation.

But at least it was still white, and some of the clamor in Biron's thoughts subsided.

There wasn't much radioactivity then. Could it be just another angle of the joke? Biron considered and decided that it couldn't. Nobody would do that to anyone else. Not on Earth, anyway, where illegal handling of radioactive material was a capital offense. They took radioactivity seriously here on Earth. They had to. So nobody would do this without overpowering reason.

He stated the thought to himself carefully and explicitly, facing it boldly. The overpowering reason, for instance, of a desire to murder. But why? There could be no motive. In his twenty-three years of life, he had never made a serious enemy. Not this serious. Not murder serious.

He clutched at his clipped hair. This was a ridiculous line of thought, but there was no escaping it. He stepped cautiously back to the closet. There had to be something there that was sending out radiation; something that had not been there four hours earlier. He saw it almost at once.

It was a little box not more than
