wly drew apart, then closed again.

"I'd guess that movement is due to rotation of two spheres around a
common center," Clay said.

"I agree with you," I said. "Try to get me a reading on the mass of the
object."

I wondered whether Kramer had been locked up as I had ordered, but at
this moment it seemed unimportant. If this was, as I hoped, a contact
with our colony, all our troubles were over.

The object (I hesitated to call it a ship) approached steadily, still
decelerating. Now Clay picked it up on the televideo, as it paralleled
our course forty-five hundred miles out.

"Captain, it's my guess the body will match speeds with us at about 200
miles, at his present rate of deceleration," Clay said.

"Hold everything you've got on him, and watch closely for anything that
might be a missile," I said.

Clay worked steadily over his chart table. Finally he turned to me.
"Captain, I get a figure of over a hundred million tons mass; and
calibrating the scope images gives us a length of nearly two miles."

I let that sink in. I had a strong and very empty feeling that this
ship, if ship it were, was not an envoy from any human colony.

The annunciator hummed and spoke. "Captain, I'm getting a very short
wave transmission from a point out on the starboard bow. Does that sound
like your torpedo?" It was Mannion.

"That's it, Mannion," I said. "Can you make anything of it?"

"No, sir," he answered. "I'm taping it, so I can go to work on it."

Mannion was our language and code man. I hoped he was good.

"What does it sound like," I asked. "Tune me in."

After a moment a high hum came from the speaker. Through it I could hear
harsh chopping consonants, a whining intonation. I doubted that Mannion
would be able to make anything of that gargle.

Our Bogie closed steadily. At four hundred twenty-five miles he reversed
relative directions, and began matching our speed, moving closer to our
course. There was no doubt he planned to parallel us.

I made a brief announcement to all hands describing the status of the
action. Clay worked over his televideo, trying to clear the image. I
watched as the blob on the screen swelled and flickered. Suddenly it
flashed into clear stark definition. Against a background of sparkling
black, the twin spheres gleamed faintly in reflected starlight.

There were no visible surface features; the iodine-colored forms and
their connecting shaft
