. She had come upon a suit and helmet by the
manual emergency lock, had run out through the lock, confused, with
her only idea to stop Wilks and me from fighting. Then she had seen
one of us killed. Impulsively, barely knowing what she was doing, she
mounted the stairs, frantic to find if I were alive.

"Anita!"

Miko was coming fast! She had not seen him; for she had no thought of
brigands--only the belief that either Wilks or I had been killed.

But now, as we stood together on the rocks near the observatory
platform, I could see the towering figure of Miko nearing the top of
the stairs.

"Anita, that's Miko! We must run!"

Then I saw my projector. It lay in a bowl-like depression quite near
us. I jumped for it. And as I tore loose from Anita, she leaped down
after me. It was a broken bowl in the rocks, some six feet deep. It
was open on the side facing the stairs--a narrow, ravinelike gully,
full of gray, broken, tumbled rock masses. The little gully was
littered with crags and boulders. But I could see out through it.

Miko had come to the head of the stairs. He stopped there, his great
figure etched sharply by the Earthlight. I think he must have known
that Coniston was the one who had fallen over the cliff, as my helmet
and Coniston's were different enough for him to recognize which was

He stood now at the summit, peering to see where we had gone. He was
no more than fifty feet from us.

"Anita, lie down."

I pulled her down on the rocks. I took aim with my projector. But I
had forgotten our helmet lights. Miko must have seen them just as I
pulled the trigger. He jumped sidewise and dropped, but I could see
him moving in the shadows to where a jutting rock gave him shelter. I
fired, missing him again.

I had stood up to take aim. Anita pulled me sharply down beside her.

"Gregg, he's armed!"

It was his turn to fire. It came--the familiar vague flash of the
paralyzing ray. It spat its tint of color on the rocks near us, but
did not reach us.

A moment later, Miko bounded to another rock.

Time passed--only a few seconds. I could not see Miko momentarily.
Perhaps he was crouching; perhaps he had moved away again. He was, or
had been, on slightly higher ground than the bottom of our bowl. It
was dim down here where we were lying, but I feared that any moment
Miko might appear and strike at us. His ray at any short range would
