Rh There had been no alarm. The slight noise we made had not been heard down on the busy deck. Anita and I crouched by the floor. From the deck all this part of the room could not be seen.

"Dead!"

"Oh, Gregg—"

It forced our hand. I could not wait now for Miko to come. But I could flash the Earth signal now, and then we would have to make our run to escape.

Abruptly I remembered that light down at the crater-base! I kept Anita out of sight on the floor and went cautiously to a window. The deck was in turmoil with brigands moving about excitedly. Not because of what had happened in our tower signal room; they were unaware of that.

Miko's signals were showing! I could see them now plainly, down at the crater-base. A group of hand-lights and a small waving helio-beam.

And they were being answered from the ship! Potan was on the deck—a babble of voices, above which his rose with roars of command. At one of the dome windows a brigand with a hand search-beam was sending its answering light. And I saw that Potan was working over a deck telescope-finder.

It had all come so suddenly that I was stunned. But I did not wait to read the signals. I swung back at Anita.

"It's Miko! And they are answering him! Get your helmet; I'll try firing the projector."

Or would I instead try to send a brief flash-signal to Earth? There would be no time to do both: we must escape out of here. The route up through the dome was the only feasible one now.

This range mechanism of the projector was reasonably familiar, and I felt that I could operate it. The range-finder and switch were on a ledge at one of the windows. I rushed to it. As I swung the little telescope, training it down on Miko's lights, I could see the huge projector on the deck swinging similarly. Its movement surprised the men who were attending it. One of them called up to me, but I ignored him.

HEN Potan looked up and saw me. He shouted in Martian at the duty-man, whom he doubtless thought was behind me: "Be ready! We may fire on them, whoever they are. I'll give you the word."

The signals were proceeding. It had only been a moment. I caught something like, "Haljan is impostor."

I was aiming the projector. I was aware of Anita at my elbow. I pushed her back.

"Put on your helmet!"

I had the range. I flung the firing switch.

At the deck window the giant projector spat its deadly electronic stream. The men down there leaped away from it with surprise. I heard Potan's voice, his shout of protest and anger.

But down in the Earthglow at the crater-base, Miko's lights had not vanished! I had missed! An error in the range? Abruptly I knew it was not that. Miko's lights were still there. His signals still coming. And I remarked now a faint distortion about them, the glow of his little group of hand-lights faintly distorted and vaguely shot with a greenish cast. Benson curve-lights! I realized it.

My thoughts whirled in the few seconds while I stood there at the tower window. Miko had feared he might summarily be fired upon. He had gone back to his camp, equipped all his lights with the Benson curve. He was somewhere at the crater-base now. But not where I thought I saw him! The Benson curve-light changed the path of the light-rays traveling from him to me—I could not even approximate his true position!

Anita was plucking at me. "Gregg, come."

"I can't hit him!" I gasped.

Should I try the flash-signal to Earth? Did we dare linger here? I
