Then the brutal madman turned, and I saw his face. If ever monstrous cruelty and malign cunning looked out of a human countenance it looked out of the eyes that stared in my direction, remorseless in their hate.

I could not tear my gaze from his face. The hate in it could be sensed, even across a blinding haze of sunlight that blotted out the sharp contours of physical things. But more than hate could be sensed. There was something tremendous about that face, as if the evil which had ravaged it had left the searing brand of Lucifer himself!

For an instant the madman stood motionless, his ghastly brutality unchallenged. Then Jeff Winters started for it. Jeff had come to Mars alone and grown more solitary with every passing day. He was a brooding, ingrown man, secretive and sullen, with a streak of wildness which he usually managed to control. He went for the madman like a gigantic terrier pup, shaggy and ferocious and contemptuous of death.

The big figure turned quickly, raised his arm, and brought his closed fist down on Jeff's skull. Jeff collapsed like a shattered plaster cast. His body seemed to break and splinter, and he sprawled forward on the sand.

He did not get up.

Frank Anders had guns on both hips, and he drew them fast. No one knew what kind of man Anders was. He hardly ever complained or made a spectacle of himself. A little guy with sandy hair and cold blue eyes, he had an accuracy of aim that did his talking for him.

His guns suddenly roared. For an instant the air between his hands and the maniac was a crackling wall of flame. The brute swayed a little but did not turn aside. He went straight for Anders with both arms spread wide.

He caught Anders about the waist, lifted him up, and slammed his body down against the sand. A sickness came over me as I stared. The madman bashed Anders' head against the ground again and again. Then suddenly the big arms relaxed and Anders sagged limply to the ground.

For an instant the madman swayed slowly back and forth, like a blood-stained marionette on a wire. Then he moved forward with a terrible, shambling gait, his head lowered, a dark, misshapen shadow seeming to lengthen before him on the sand like a spindle of flame.

The clearing was abruptly tumultuous with sound. The fury which had been unleashed against me turned upon the monster and became a closed circle of deadly, intent purpose hemming him in—and he was caught in a crossfire that hurled him backwards to the sand.
