Mury paused in his long stride, removed a hand from a pocket of the gray topcoat that wrapped him as in somber thoughts. Wordlessly, he pointed as Ryd had known he would--toward where a pale man-made dawn seemed breaking over Pi Mesa. II "One blow for freedom!" said Mury with caught breath. His voice fell upon air scarcely stilled since the sodden thump of the blow that had killed the guard. The body lay between them, face down on the graveled way in the inky moon-shadow. On one side Pi Mesa stretched away two hundred yards to drop sharply into the night; on the other was the unlighted mass of the long, continuous, low buildings that housed now unused fuel pumps and servicing equipment. Looking down at the dead huddle at his feet, a little stunned by the reality of this, Ryd knew that he was in it now. He was caught in the machinery. Mury hefted the length of steel in his hand once more, as if testing the weight that had crushed a man's skull so easily. Then, with a short wrist-flip, he sent it flying into the dried weeds which had over-grown the aero field on the mesa's rim during the summer months after State order had grounded all fliers in America. "All right, Ryd," he said coolly. "Trade clothes with this fellow. I've brought you this far--you're taking me the rest of the way." The rest of the way. Ryd was still panting, and his side was paining from the strenuous exertion of the long climb up the side of the mountain, far from the guarded highway. His fingers, numbed by the cold of the high, thin air, shook as he knelt and fumbled with the zippers of the dead guard's uniform. The belted gun, however, was heavy and oddly comforting as he clumsily buckled it about his hips. He knew enough of weapons to recognize this as, not the usual paralyzer, but a flame pistol, powerful and deadly. He let his hand linger on its butt; then strong fingers tightened on his bony wrist, and he looked up with a start into the sardonic black eyes of the Panclast. "No use now for firearms," said Mury. "All the guns we could carry wouldn't help us if we were caught out there. That gun is just a stage property for the little play we're going to give in about three minutes--when you'll act a guardsman escorting me, a Poligerent of Dynamopolis, aboard the towship _Shahrazad_." For a moment Ryd felt relief--he had hazily imagined that Mury's hatred of Mars and all things Martian might have led him to try to sabotage the Martian warship which lay somewhere on the runways beyond the long, low buildings, and which would be closely guarded. But the towship would also be guarded ... he shivered in the cold, dry night air. Mury had melted into the shadow a few yards away. There was a light scraping, then a green flame sputtered, briefly lighting up his hands and face, and narrowing at once to a thin, singing needle of light. He had turned a pocket electron torch against the lock-mechanism of a small, disused metal door.
