"Take us to where Axelson is."
"First you must destroy the guards. I sent the one on duty here away on some pretext. But the others may be here at any moment. Talk lower.
Are you going to kill them?"
"We must," said Nat.
The old fellow began to sob. "We were companions together. They seized us and imprisoned us together, the capitalists, years ago. I thought the proletariat would have won, and you say it is all different. I am an old man, and life is sad and strange."
"Listen. Is Axelson in the house?" demanded Nat.
"He is in his secret room. I do not know the way. None of us has ever entered it."
"And Madge?"
"She was with him. I do not know anything more." He sank down, groaning, broken.
Nat pushed his way past him. It was fast growing light now. A ray of sunshine shot from beneath the edge of the dark sphere overhead, which still filled almost all the heavens. At that moment the hideous face and squat body of one of the Moon men came into view at the end of the path. The creature stopped, gibbering with surprise, and then rushed forward, mewing like a cat.
Nat aimed his ray-rod and pressed the b.u.t.ton. The streak of light, not quite aimed, in Nat"s excitement, sheared off one side of the Moon man"s face.
The creature rocked where it stood, raised its voice in a screech, and rushed forward again, arms flailing. And this time Nat got home. The streak pa.s.sed right through the body of the monster, which collapsed into a heap of calcined carbon.
But its screech had brought the other dwarfs running to the scene. In a moment the path was blocked by a score of the hideous monsters, which, taking in what was happening, came forward in a yelling bunch.
The ray-rods streaked their message of death into the thick of them.
Yet so fierce was the rush that some parts got home. Arms, legs, and barrel chests, halves of men, covering the five with that impalpable black powder into which their bodies were dissolving. Nat remembered afterward the horror of a grinning face, apparently loose in the air, and a flailing arm that lashed his chest.
For fifteen seconds, perhaps, it was like struggling with some vampire creatures in a hideous dream. And then, just when it seemed to Nat that he was going mad, he found the path free, and the huddled remnants of the Moon men piled up about him on every side.
He emptied two more ray-shots into the writhing ma.s.s, and saw it cease to quiver and then dissolve into the black powder. He turned and looked at his companions. They, too, showed the horror of the strain they had undergone.
"We must kill the guards now," Nat panted. "And then find Madge and save her."
"We"re with you," answered Brent, and together the five rushed into the sunlight and the open.
There were no guards on duty at the entrance of the house, and the door stood wide open. Nat rushed through the door at the head of his men. A single guard was in the hall, but he only looked up as they came in. And it was evident that he was in no condition to resist, for he was in the grip of some terrible disease.
His features were swollen so that they were hardly recognizable, and hoa.r.s.e, panting breaths came from his lungs. He was so far gone that he hardly registered surprise at the advent of the five.
"Where"s Axelson?" demanded Nat.
The guard pointed toward the end of the corridor, then let his arm fall. Nat led his men along the half-dark pa.s.sage.
At the end of the corridor two more guards were on duty, but one was collapsed upon the floor, apparently unconscious, and the other, making a feeble attempt to draw his ray-rod, crumbled into ashes as Brent fired. The five burst through the door.
They found themselves in the banquet-hall. The remnants of the meal were still upon the table, and three Moon men, looking as if they had been poisoned, were writhing on the floor. At the farther end of the hall was another door.
This gave upon a central hall, with a door in each of its four sides, and a blaze of sunlight coming through the crystal roof. The five stopped, baffled. Then of a sudden Axelson"s voice broke the silence--his voice, yet changed almost beyond recognition, hoa.r.s.e, broken, and gasping:
"Try the doors, Nathaniel Lee. Try each door in turn, and then go back. And know that in an instant I can blast you to nothingness where you stand!"
And suddenly there came Madge"s voice, "He can"t! He can"t, Nat. He"s dying, and he knows it. I won"t let him, and he hasn"t got the strength to move."
"Which door?" cried Nat in desperation.
"None of the doors. They"re a trick," came Madge"s voice. "Go forward and press the grooved panel upon the wall in front of you."
Nat stepped forward, found the panel, and pressed it. The wall swung open, like two folded doors, revealing another room within, perfectly circular.
It contained a quant.i.ty of pieces of apparatus, some glowing with light, some dark, and a radio transmitting set; it was evidently the secret lair of the Black Caesar. And there he was, trapped at last by the mortal illness that had overtaken him!
He was lying upon the couch, his great form stretched out, his features hideously swollen by the same disease that had attacked the guards.
Nat raised his ray-rod, but Axelson feebly put up his hand, and Nat lowered the weapon. And, as the five gathered about the dying man, again Nat felt that strange sense of pathos and pity for him.
He had never known Earth life, and he was not to be measured by the common standards applicable on Earth.
"Don"t fire, Nat," said Madge in a shaky voice. She was seated beside Axelson, and--the wonder of it--she was sponging the foam from his lips and moistening his forehead. She raised a crystal that contained some fluid to his lips, and he drained it greedily.
"So--Earth wins, Nathaniel Lee," whispered Axelson hoa.r.s.ely. "I am dying. I know it. It is the same dreaded disease that came to the Moon at the time of my father"s landing there. Three-fourths of the Moon animals died. It is mortal. The lungs burn away.
"My father told me that on Earth it is not mortal. He called it "cold"--but I am burning hot."
Then only did Nat understand, and the irony of it made him catch his breath and grit his teeth to check his hysterical laughter. The Black Caesar, the terror of Earth, was dying of a common cold which he himself had given him.
The coryza germ, almost harmless on Earth, among a population habituated to it for countless generations, had a.s.sumed the potency of a plague here, where no colds had ever been known--among the Moon men, and even among the guards, after their lifetime in the germless climate of Eros.
"I"ve failed, Nathaniel Lee," came the Black Caesar"s voice. "And yet that hardly troubles me. There is something more that I do not understand. She is a creature like ourselves--with will and reason.
She is not like the Moon women. She told me that she did not wish to be queen of the Earth because she did not love me. I do not understand. And so--I am glad to go."
A gasp came from Axelson"s throat as he raised his head and tried to speak, but the death-rattle was already in his throat. A slight struggle, and the ma.s.sive form upon the couch was nothing but inanimate clay.
Madge rose from beside him, and the tears were streaming down her face.
"He wasn"t a bad man, Nat," she said. "He was--gentle with me. He didn"t understand; that was all. When I refused to be his queen, he was overcome with bewilderment. Oh, Nat, I can never, never write this story for the Universal News Syndicate."
Nat led her, sobbing, from the room.
Soon he succeeded in getting into teleradio communication with Earth.
He broadcast the news that the Black Caesar was dead, and that his power for evil was at an end forever.
