What was he doing with a hand-helio? Our watchmen, I knew, had no reason to carry one.
And to whom could Wilks be signalling across this Lunar desolation?
The answer stabbed at me: to Miko"s band!
I waited another moment. No further light. Wilks was still up there!
I went back to the lock entrance. Spare suits and helmets were here beside the keeper. He gazed at me inquiringly.
"I"m going out, Franck, just for a minute." It struck me that perhaps I was a meddlesome fool. Wilks, of all Grantline"s men, was, I knew, most in his commander"s trust. The signal could have been some part of this night"s ordinary routine, for all I knew.
I was hastily donning an Erentz suit. I added, "Let me out. I just got the idea Wilks is acting queerly." I laughed. "Maybe the Earthlight has touched him."
With my helmet on I went through the locks. Once outside, with the outer panel closed behind me, I dropped the weights from my belt and shoes and extinguished my helmet-light.
Wilks was still up there. Apparently he had not moved. I bounded off across the ledge to the foot of the ascending stairs. Did Wilks see me coming? I could not tell. As I approached the stairs the platform was cut off from my line of vision.
I mounted with bounding leaps. In my flexible gloved hand I carried my only weapon, a small bullet projector with oxygen firing caps for use in this outside near-vacuum. The leaden bullet with its slight ma.s.s would nevertheless pierce a man at the distance of twenty feet.
I held the weapon behind me. I would talk to Wilks first.
I went slowly up the last hundred feet. Was Wilks still up there? The summit was bathed in Earthlight. The little metal observatory platform came into view above my head.
Wilks was not there. Then I saw him standing on the rocks nearby, motionless. But in a moment he saw me coming.
I waved my left arm with a gesture of greeting. It seemed to me that he started, made as though to leap away, then changed his mind and waited for me.
I sailed from the head of the staircase with a twenty-foot leap and landed lightly beside him. I gripped his arm for audiphone contact.
"Wilks!"
Through the visors his face was visible. I saw him, and he saw me. And I heard his voice.
"You, Haljan! How nice!"
It was not Wilks, but the brigand Coniston!
CHAPTER XXIV
_Imprisoned!_
The duty-man at the exit locks of the main building stood at his window and watched me curiously. He saw me go up the spider-stairs. He could see the figure he thought was Wilks, standing at the top. He saw me join Wilks, saw us locked together in combat.
For an instant the duty-man stood amazed. There were two fantastic, misshapen figures swaying in the Earthlight five hundred feet above the camp, fighting desperately at the very brink. They were small, dwarfed by distance, alternately dim and bright as they swayed in and out of the shadows. Soon the duty-man could not tell one from the other. Haljan and Wilks--fighting to the death!
The duty-man recovered himself and sprang into action. An interior siren-call was on the instrument panel near him. He rang it, alarming the camp.
The men came rushing to him, Grantline among them.
"What"s this? Good G.o.d, Franck!"
They saw the silent, deadly combat up there on the cliff. The two figures had fallen together from the observatory platform, dropped twenty feet to a lower landing on the stairs. They lay as though stunned for a moment, then fought on.
Grantline stood stricken with amazement. "That"s Wilks!"
"And Haljan," the duty-man gasped. "Went out--something wrong with Wilks--acting strangely--"
The interior of the camp was in a turmoil. The men awakened from sleep, ran out into the corridors, shouted questions.
"An attack?"
"Is it an attack?"
"The brigands?"
But it was Wilks and Haljan in a fight out there on the cliff. The men crowded at the bulls"-eye windows.
And over all the confusion the alarm siren, with no one thinking to shut it off, was screaming with its electrical voice.
Grantline, stricken for that moment of inactivity, stood gazing. One of the figures broke away from the other, bounded up to the summit from the stair-platform to which they had fallen. The other followed.
They locked together, swaying at the brink. For an instant it seemed to Grantline that they would go over; then they surged back, momentarily out of sight.
Grantline found his wits. "Stop them! I"ll go out to stop them! What fools!"
He was hastily donning one of the Erentz suits which stood at the lock entrance. "Shut off that siren, Franck!"
Within a minute Grantline was ready. The duty-man called from the window:
"Still at it! By the infernal, such fools! They"ll kill themselves!"
The figures had swayed back into view, then out of sight again.
"Franck, let me out."
Grantline was ready. He stood, helmet in hand.
"I"ll go with you, Commander."
But the volunteer was not equipped. Grantline would not wait.
"I"m going at once. Hurry, Franck."
The duty-man turned to his panel. The volunteer shoved a weapon at Grantline. "Here, take this."
Grantline jammed on his helmet.
