"Messages have been coming in from all over Europe," the colonel was saying. "Here's the way it reconstructs:

"Our agent was en route to the rendezvous when he was intercepted by Naomi. That's the only name we have for her. She's a spy. She's worked for half a dozen countries and her present employer could be any one of them. They were spotted as they crossed the frontier between Italy and France. Their car went into a barn and we thought we had them. But the barn turned out to be a spaceship in disguise. It took off."

So I'm their agent, Paul Asher thought. So that's what it's all about. I'm a secret agent for the United States, but they didn't tell me anything about it. This is real George, this is ... He expected to hear a faint click and leaned forward experimentally, but nothing happened. He leaned backward. Still nothing.

The colonel was answering a question from the general. "We don't know who they are, Sir. They're not from Earth, obviously. And the best scientific minds go still further—they're not even from our solar system. Whoever they are, it's clear that they don't want us to build a way-station in space."

"Those spaceships started buzzing around right after our first Moon trip," the general said. "This is the first time they've become really troublesome—now that we've got the Moon under control and are ready to build the way-station so we can get to Mars."

"That's right, Sir," said the colonel.

"Progress is a wonderful thing," said the general. "Things certainly have changed since those early days of strategic atomic bombing and guided missile experiments."

"Yes, Sir," said the colonel.

The young man in the communications room of the spaceship let his attention wander away from the scene back on Earth and experimented with some of the switches and controls. Trial and error led him to one which lit up a signal on the desk of the general.

The general flicked it on.
