He was being paid to take a risk. He had volunteered for the job. And he knew that high above, circling at twenty thousand feet, was an Air Force jet with air-to-air missiles. It was the job of the jet to shoot down the helicopter should the pilot suffer a last-minute loss of nerve and fail to go directly to Wildfire.

"Don't slip up," the pilot said. "Sir."

The helicopter maneuvered over the main street of the town and hung in midair. There was a rattling sound: the rope ladder being released. Stone stood and pulled on his helmet. He snapped shut the sealer and inflated his clear suit, puffing it up around him. A small bottle of oxygen on his back would provide enough air for two hours of exploration.

He waited until Burton had sealed his suit, and then Stone opened the hatch and stared down at the ground. The helicopter was raising a heavy cloud of dust.

Stone clicked on his radio. "All set?"

"All set."

Stone began to climb down the ladder. Burton waited a moment, then followed. He could see nothing in the swirling dust, but finally felt his shoes touch the ground. He released the ladder and looked over. He could barely make out Stone's suit, a dim outline in a gloomy, dusky world.

The ladder pulled away as the helicopter lifted into the sky. The dust cleared. They could see.

"Let's go," Stone said.

Moving clumsily in their suits, they walked down the main street of Piedmont.

7. "An Unusual Process"

SCARCELY TWELVE HOURS after the first known human contact with the Andromeda Strain was made at Piedmont, Burton and Stone arrived in the town. Weeks later, in their debriefing sessions, both men recalled the scene vividly, and described it in detail.

The morning sun was still low in the sky; it was cold and cheerless, casting long shadows over the thinly snow-crusted ground. From where they stood, they could look up and down the street at the gray, weathered wooden buildings; but what they noticed first was the silence. Except for a gentle wind that whined softly through the empty houses, it was deathly silent. Bodies lay everywhere, heaped and flung across the ground in attitudes of frozen surprise.

But there was no sound—no reassuring rumble of an automobile engine, no barking dog, no shouting children.

Silence.

The two men looked at each other. They were painfully aware of how much there was to learn, to do. Some catastrophe had struck this town, and they must discover all they could about it. But they had practically no clues, no points of departure.

They knew, in fact, only two things. First, that the trouble apparently began with the landing of Scoop VII. And second, that death had overtaken the people of the town with astonishing rapidity. If it was a disease from the satellite, then it was like no other in the history of medicine.

For a long time the men said nothing, but stood in the street, looking about them, feeling the wind tug at their oversized suits. Finally, Stone said, "Why are they all outside, in the street? If this was a disease that arrived at night, most of the people would be indoors."
