A key rattled in the lock and Luke Fenton leaped to his feet, facing the barred door with feet spread wide and with his massive shoulders hunched expectantly. He could see now, with much blinking and watering of his still aching eyes, and he looked out with sneering disapproval at the three guards in the corridor. They were afraid of him, singly, these Martian cops, even though armed with the deadly dart guns and with shot-loaded billies. So afraid, Luke chuckled inwardly, that they had kept him from the other prisoners throughout the trip, kept him in solitary confinement. The door was opening and it came to Luke that the ethership was strangely and hollowly silent. The rocket tubes were stilled, that was it, and even the motors that drove the great ventilating fans had been stopped. They had arrived. No time now to start anything. He would have to submit tamely to whatever they might mete out to him in the way of punishment--until he got the lay of the land. It would require some time to study things out and to plan. But plan he would, and act; they'd never hold him here until he died of whatever it was that killed men quickly in Vulcan's Workshop. Not Luke Fenton. Sullenly docile, he was prodded forward to the air-lock. A draft of hot fetid air swept through the corridor, carrying with it the forewarning of unspeakable things to come. And a shriek of mortal terror wafted in from outside by the stinking breeze, told of some poor devil already demoralized. The thick muscles of Luke's biceps tightened to hard knots under his black prison jacket. * * * * * They were outside then and Luke essayed a deep breath, a breath that was chokingly acrid in his throat. "Waugh!" he coughed, and spat. One of the guards laughed. Any foul epithet that might have formed on Fenton's lips was forgotten in the sight that met his eyes. A barren and rugged terrain stretched out from the landing stage, a land utterly desolate of vegetation and incapable of supporting life. Pockmarked with craters and seamed with yawning fissures from which dense vapors curled, it was seemingly devoid of habitation. And the scene was visible only in the lurid half light of flame-shot mists that hung low over all. In the all too near distance, awesomely vast and ruddy columns of fire rose and fell with monotonous regularity. For the first time, Luke experienced something of the superstitious fear exhibited by even the most hardened criminals when faced with a term at Vulcan's Workshop. That term, to them, meant horror and misery, torture and swift death. And he, too, was ready to believe it now.
