<h2>XXIV</h2>
<p>The duty man at the exit locks 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.</p>
<p>For a brief instant the duty man stood amazed. There were two
fantastic figures, fighting at the very brink of the cliff. They were
small, dwarfed by distance, alternately dim and bright as they swayed
in and out of the shadows. The duty man could not tell one from the
other. To him it was Haljan and Wilks, fighting to the death!</p>
<p>The duty man sprang into action. An interior siren call was on the
instrument panel near him. He rang it frantically.</p>
<p>The men came rushing to him, Grantline among them.</p>
<p>"What's this? Good God, Franck!"</p>
<p>They had seen the silent, deadly combat up there on the cliff.</p>
<p>Grantline stood stricken with amazement. "That's Wilks!"</p>
<p>"And Haljan," the duty man gasped. "He went out—something wrong with
Wilks' actions—"</p>
<p>The interior of the camp was in a turmoil. The men, awakened from
sleep, ran out into the corridors shouting questions.</p>
<p>"An attack?"</p>
<p>"Is it an attack?"</p>
<p>"The brigands?"</p>
<p>But it was Wilks and Haljan in a fight up there on the cliff. The men
crowded at the bull's-eye windows.</p>
<p>And over all the confusion the alarm siren, with no one thinking to
shut it off, was screaming.<span class="pagenum"><SPAN name="Page_150" id="Page_150"></SPAN></span></p>
<p>Grantline, momentarily stricken, stood gazing. One of the figures
broke away from the other, bounded up to the summit from the stair
platform to which they had both fallen. The other followed. They
locked together, swaying at the brink. For an instant it seemed that
they would go over; then they surged back, momentarily out of sight.</p>
<p>Grantline found his wits. "Stop them! I'll go out and stop them! What
fools!"</p>
<p>He was hastily donning one of the Erentz suits. "Cut off that siren!"</p>
<p>Within a minute Grantline was ready. The duty man called from the
window, "Still at it, the fools. By the infernal—they'll kill
themselves!"</p>
<p>"Franck, let me out."</p>
<p>"I'll go with you, Commander." But the volunteer was not equipped.
Grantline would not wait.</p>
<p>The duty man turned to his panel. The volunteer shoved a weapon at
Grantline.</p>
<p>Grantline jammed on his helmet, took the weapon.</p>
<p>He moved the few steps into the air chamber which was the first of the
three pressure locks. Its interior door panel swung open for him. But
the door did not close after him!</p>
<p>Cursing the man's slowness, he waited a few seconds. Then he turned to
the corridor. The duty man came running.</p>
<p>Grantline took off his helmet. "What in hell—"</p>
<p>"Broken! Dead!"</p>
<p>"What!"</p>
<p>"Smashed from outside," gasped the duty man. "Look there—my tubes—"</p>
<p>The control tubes of the ports had flashed into a short circuit and
burned out. The admission ports would not open!</p>
<p>"And the pressure controls smashed! Broken from outside!"</p>
<p>There was no way now of getting through the pressure locks. The doors,
the entire pressure lock system, was dead. Had it been tampered with
from outside?<span class="pagenum"><SPAN name="Page_151" id="Page_151"></SPAN></span></p>
<p>As if to answer Grantline's question there came a chorus of shouts
from the men at the corridor windows.</p>
<p>"Commander! By God—look!"</p>
<p>A figure was outside, close to the building! Clothed in suit and
helmet, it stood, bloated and gigantic. It had evidently been lurking
at the port entrance, had ripped out the wires there.</p>
<p>It moved past the windows, saw the staring faces of the men, and made
off with giant bounds. Grantline reached the window in time to see it
vanish around the building corner.</p>
<p>It was a giant figure, larger than an Earth man. A Martian?</p>
<hr style='width: 45%;' />
<p>Up on the summit of the crater the two small figures were still
fighting. All this turmoil had taken no more than a minute or two.</p>
<p>A lurking Martian outside? The brigand, Miko? More than ever,
Grantline was determined to get out. He shouted to his men to don some
of the other suits, and called for some of the hand projectors.</p>
<p>But he could not get out through these main admission ports. He could
have forced the panels open perhaps; but with the pressure changing
mechanism broken, it would merely let the air out of the corridor. A
rush of air, probably uncontrollable. How serious the damage was, no
one could tell as yet. It would perhaps take hours to repair it.</p>
<p>Grantline was shouting, "Get those weapons! That's a Martian outside!
The brigand leader, probably! Get into your suits, anyone who wants to
go with me! We'll go by the manual emergency exit."</p>
<p>But the prowling Martian had found it! Within a minute Grantline was
there. It was a smaller two-lock gateway of manual control, so that
the person going out could operate it himself. It was in a corridor at
the other end of the main building. But Grantline was too late! The
lever would not open the panels!</p>
<p>Had someone gone out this way and broken the mechan<span class="pagenum"><SPAN name="Page_152" id="Page_152"></SPAN></span>isms after him? A
traitor in the camp? Or had someone come in from outside? Or had the
skulking Martian outside broken this lock as he had broken the other?</p>
<p>The questions surged on Grantline. His men crowded around him. The
news spread. The camp was a prison! No one could get out!</p>
<p>And outside, the skulking Martian had disappeared. But Wilks and
Haljan were still fighting. Grantline could see the two figures up on
the observatory platform. They bounded apart, then together again.
Crazily swaying, bouncing, striking the rail.</p>
<p>They went together in a great leap off the platform onto the rocks,
and rolled in a bright patch of Earthlight. First one on top, then the
other.</p>
<p>They rolled unheeding to the brink. Here, beyond the midway ledge
which held the camp, it was a sheer drop of a thousand feet, on down
to the crater floor.</p>
<p>The figures were rolling; then one shook himself loose; rose up,
seized the other and, with desperate strength, shoved him—</p>
<p>The victorious figure drew back to safety. The other fell, hurtling
down into the shadows past the camp level—down out of sight in the
darkness of the crater floor.</p>
<p>Snap, who was in the group near Grantline at the window gasped, "God!
Was that Gregg who fell?"</p>
<p>No one could say. No one answered. Outside, on the camp ledge, another
helmeted figure now became visible. It was not far from the main
building when Grantline first noticed it. It was running fast,
bounding toward the spider staircase. It began mounting.</p>
<p>And now still another figure became visible—the giant Martian again.
He appeared from around the corner of the main Grantline building. He
evidently saw the winner of the combat on the cliff, who now was
standing in the Earthlight, gazing down. And he saw too, no doubt, the
second figure mounting the stairs. He stood quite near the window
through which Grantline and his men were gazing, with his<span class="pagenum"><SPAN name="Page_153" id="Page_153"></SPAN></span> back to the
building, looking up to the summit. Then he ran with tremendous leaps
toward the ascending staircase.</p>
<p>Was it Haljan standing up there on the summit? Who was it climbing the
stairs? And was the third figure Miko?</p>
<p>Grantline's mind framed the questions. But his attention was torn from
them, and torn even from the swift silent drama outside. The corridor
was ringing with shouts.</p>
<p>"We're imprisoned! Can't get out! Was Haljan killed? The brigands are
outside!"</p>
<p>And then an interior audiphone blared a calling for Grantline. Someone
in the instrument room of the adjoining building was talking.</p>
<p>"Commander, I tried the telescope to see who got killed—"</p>
<p>But he did not say who got killed, for he had greater news.</p>
<p>"Commander! The brigand ship!"</p>
<p>Miko's reinforcements had come.</p>
