Four and one half hours after Martian sunset, the last light in the Headquarters Building finally blinked out.

Carl Golden stamped his feet nervously against the cold, cupping his cigarette in his hand to suck up the tiny spark of warmth. The night air bit his nostrils and made the smoke tasteless in the darkness. Atmosphere screens kept the oxygen in, all right—but they never kept the biting cold out. As the light disappeared he dropped the cigarette, stamping it sharply into darkness. Boredom vanished, and warm blood prickled through his shivering legs.

He slid back tight against the coarse black building front, peering across the road in the gloom.

It was the girl. He had thought so, but hadn't been sure. She swung the heavy stone door shut after her, glanced both left and right, and started down the frosty road toward the lights of the colony.

Carl Golden waited until she was gone. He glanced at his wrist-chrono, and waited ten minutes more. He didn't realize that he was trembling until he ducked swiftly across the road. Through the window of the low, one-story building he could see the lobby call-board, with the little colored studs all dark. He smiled in unpleasant satisfaction—no one was left in the building. It was routine, just like everything else in this god-forsaken hole. Utter, abysmal, trancelike routine. The girl was a little later than usual, probably because of the ship coming in tomorrow. Reports to get ready, supply requisitions, personnel recommendations—

—and the final reports on Armstrong's death. Mustn't forget that. The real story, the absolute, factual truth, without any nonsense. The reports that would go, ultimately, to Rinehart and only Rinehart, as all other important reports from the Mars Colony had been doing for so many years.

Carl skirted the long, low building, falling into the black shadows of the side wall. Halfway around he came to the supply chute, covered with a heavy moulded-stone cover.

Now?

It had taken four months here to know that he would have to do it this way. Four months of ridiculous masquerade—made idiotic by the incredible fact that everyone took him for exactly what he pretended to be, and never challenged him—not even Terry Fisher, who drunk or sober always challenged everything and everybody! But the four months had told on his nerves, in his reactions, in the hollows under his quick brown eyes. There was always the spectre of a slip-up, an aroused suspicion. And until he had the reports before his eyes, he couldn't fall back on Dan Fowler's name to save him. He had shook Dan's hand the night he had left, and Dan had said, "Remember, son—I don't know you. Hate to do it this way, but we can't risk it now—" And they couldn't, of course. Not until they knew, for certain, who had murdered Kenneth Armstrong.

They already knew why.

The utter stillness of the place reassured him; he hoisted up the chute cover, threw it high, and shinned his long body into the chute. It was a steep slide; he held on for an instant, then let go. Blackness gulped him down as the cover snapped closed behind him.

He struck hard and rolled. The chute opened into the commissary in the third deep-level of the building, and the place was black as the inside of a pocket. He tested unbroken legs with a sigh of relief, and limped across to where the door should be.

In the corridor there was some light—dim phosphorescence from the Martian night-rock lining the walls and tiling the floor. He walked swiftly, cursing the clack-clack his heels made on the ringing stone. When he reached the end of the corridor he tried the heavy door.

It gave, complaining. Good, good! It had been a quick, imperfect job of jimmying the lock, so obviously poor that it had worried him a lot—but why should they test it? There was still another door.

He stepped into the blackness again, started across the room as the door swung shut behind him.

A shoe scraped, the faintest rustle of sound. Carl froze. His own trouser leg? A trick of acoustics? He didn't move a muscle.

Then: "Carl?"

His pocket light flickered around the room, a small secretary's ante-room. It stopped on a pair of legs, a body, slouched down in the soft plastifoam chair—a face, ruddy and bland, with a shock of sandy hair, with quixotic eyebrows. "Terry! For Christ sake, what—"

The man leaned forward, grinning up at him. "You're late, Carl." His voice was a muddy drawl. "Should have made it sooner than this, sheems—seems to me."

Carl's light moved past the man in the chair to the floor. The bottle was standing there, still half full. "My god, you're drunk!"

"Course I'm drunk. Whadj-ya think, I'd sober up after you left me tonight? No thanks, I'd rather be drunk." Terry Fisher hiccupped loudly. "I'd always rather be drunk, around this place."

"All right, you've got to get out of here—" Carl's voice rose with bitter anger. Of all times, of all times—he wanted to scream. "How did you get in here? You've got to get out—"

"So do you. They're on to you, Carl. I don't think you know that, but they are." He leaned forward precariously. "I had a talk with Barness this morning, one of his nice 'spontaneous' chats, and he pumped the hell out of me and thought I was too drunk to know it. They're expecting you to come here tonight—"

Carl heaved at the drunken man's arm, frantically in the darkness. "Get out of here, Terry, or so help me—"

Terry clutched at him. "Didn't you hear me? They know about you. Personell supervisor! They think you're spying for the Eastern boys—they're starting a Mars colony too, you know. Barness is sure you're selling them info—" The man hiccupped again. "Barness is an ass, just like all the other Retreads running this place, but I'm not an ass, and you didn't fool me for two days—"

Carl gritted his teeth. How could Terry Fisher know? "For the last time—"

Fisher lurched to his feet. "They'll get you, Carl. They can try you and shoot you right on the spot, and Barness will do it. I had to tell you, you've walked right into it, but you might still get away if—"

It was cruel. The drunken man's head jerked up at the blow, and he gave a little grunt, then slid back down on the chair. Carl stepped over his legs, worked swiftly at the door beyond. If they caught him now, Terry Fisher was right. But in five more minutes—

The lock squeaked, and the door fell open. Inside he tore through the file cases, wrenched at the locked drawers in frantic haste, ripping the weak aluminum sheeting like thick tinfoil. Then he found the folder marked KENNETH ARMSTRONG on the tab.

Somewhere above him an alarm went off, screaming a mournful note through the building. He threw on the light switch, flooding the room with whiteness, and started through the papers, one by one, in the folder. No time to read. Flash retinal photos were hard to superimpose and keep straight, but that was one reason why Carl Golden was on Mars instead of sitting in an office back on Earth—

He flipped the last page, and threw the folder onto the floor. As he went through the door, he flipped out the light, raced with clattering footsteps down the corridor.

Lights caught him from both sides, slicing the blackness like hot knives. "All right, Golden. Stop right there."

Dark figures came out of the lights, ripped his clothing off without a word. Somebody wrenched open his mouth, shined a light in, rammed coarse cold fingers down into his throat. Then: "All right, you bastard, up stairs. Barness wants to see you."

They packed him naked into the street, hurried him into a three-wheeled ground car. Five minutes later he was wading through frosty dust into another building, and Barness was glaring at him across the room.

Odd things flashed through Carl's mind. You seldom saw a Repeater get really angry—but Barness was angry. The man's young-old face (the strange, utterly ageless amalgamation of sixty years of wisdom, superimposed by the youth of a twenty-year-old) had unaccustomed lines of wrath about the eyes and mouth. Barness didn't waste words. "What did you want down there?"

"Armstrong." Carl cut the word out almost gleefully. "And I got it, and there's nothing you or Rinehart or anybody else in between can do about it. I don't know what I saw yet, but I've got it in my eyes and in my cortex, and you can't touch it."

"You stupid fool, we can peel your cortex," Barness snarled.

"Well, you won't. You won't dare."

Barness glanced across at the officer who had brought him in. "Tommy—"

"Dan Fowler won't like it," said Carl.

Barness stopped short, blinking. He took a slow breath. Then he sank down into his chair. "Fowler" he said, as though dawn were just breaking.

"That's right. He sent me up here. I've found what he wants. Shoot me now, and when they probe you Dan will know I found it, and you won't be around for another rejuvenation."

Barness looked suddenly old. "What did he want?"

"The truth about Armstrong. Not the 'accident' story you fed to the teevies.... "Tragic End for World Hero, Died With His Boots On". Dan wanted the truth. Who killed him. Why this colony is grinding down from compound low to stop, and turning men like Terry Fisher into alcoholic bums. Why this colony is turning into a glorified, super-refined Birdie's Rest for old men. But mostly who killed Armstrong, how he was murdered, who gave the orders. And if you don't mind, I'm beginning to get cold."

"And you got all that," said Barness.

"That's right."

"You haven't read it, though."

"Not yet. Plenty of time for that on the way back."

Barness nodded wearily, and motioned the guard to give Carl his clothes. "I think you'd better read it tonight. Maybe it'll surprise you."

Golden's eyes widened. Something in the man's voice, some curious note of defeat and hopelessness, told him that Barness was not lying. "Oh?"

"Armstrong didn't have an accident, that's true. But nobody murdered him, either. Nobody gave any orders, to anybody, from anybody. Armstrong put a bullet through his head—quite of his own volition."
