Isaac Azimov: Let’s Get Together

"I think it’s a good one, Breckenridge. But it wouldn’t work unless we knew humanoids were in America so that we would call the conference in the first place. Quite a coincidence that you brought the news of the humanoids and suggested the conference and suggested the agenda and are running the show and know exactly which scientists were invited. Did you make sure the right ten were included?”

"Dr. Lynn!” cried Breckenridge in outrage. He poised to rush forward.

Lynn said, "Don’t move. I’ve got a blaster here. We’ll just wait for the scientists to get here one by one. One by one we’ll X-ray them. One by one, we’ll monitor them for radioactivity. No two will get together without being checked, and if all five hundred are clear, I’ll give you my blaster and surrender to you. Only I think we’ll find the ten humanoids. Sit down, Breckenridge.”

They both sat.

Lynn said, "We wait. When I’m tired, Laszlo will spell me. We wait.”

Professor Manuelo Jiminez of the Institute of Higher Studies of Buenos Aires exploded while the stratospheric jet on which he traveled was three miles above the Amazon Valley. It was a simple chemical explosion but it was enough to destroy the plane.

Dr. Herman Liebowitz of M. I. T. exploded in a monorail, killing twenty people and injuring a hundred others.

In similar manner, Dr. Auguste Marin of L’Institut Nuc- leonique of Montreal and seven others died at various stages of their journey to Cheyenne.

Laszlo hurtled in, pale-faced and stammering, with the first news of it. It had only been two hours that Lynn had sat there, facing Breckenridge, blaster in hand.

Laszlo said, "I thought you were nuts, Chief, but you were right. They were humanoids. They had to be.” He turned to stare with hate-filled eyes at Breckenridge. "Only they were warned. He warned them, and now there won’t be one left intact. Not one to study.”

"God!” cried Lynn and in a frenzy of haste thrust his blaster out toward Breckenridge and fired. The Security man’s neck vanished; the torso fell; the head dropped, thudded against the floor and rolled crookedly.

Lynn moaned, "I didn't understand, I thought he was a traitor. Nothing more.”

And Laszlo stood immobile, mouth open, for the moment incapable of speech.

Lynn said, wildly. "Sure, he warned them. But how could he do so while sitting in that chair unless he were equipped with built-in radio transmission? Don’t you see it? Breckenridge had been in Moscow. The real Breckenridge is still there. Oh my God, there were eleven of them.”

Laszlo managed a hoarse squeak. "Why didn’t he explode?”

"He was hanging on, I suppose, to make sure the others had received his message and were safely destroyed. Lord, Lord, when you brought the news and I realized the truth, I couldn’t shoot fast enough. God knows by how few seconds I may have beaten him to it.”

Laszlo said, shakily, "At least, we’ll have one to study.” He bent and put his fingers on the sticky fluid trickling out of the mangled remains at the neck end of the headless body.

Not blood, but high-grade machine oil.
