"All right," he said reasonably. They had perhaps six minutes more before the doctor and the emergency medical carrier arrived on rooftop. "Who did make it?"

  "The alloy was developed on Bellatrix." She spoke jerkily, word by word. "The rind ... forms a skin on the outside, a bubble that gets sucked in and out of a reservoir. That's its rind, the TV shape. It sucks it back and becomes the M; it's ready to act."

  "What made it?" he repeated.

  "A Bellatrix machine tool syndicate ... a subsidiary of Tirol's organization. They're made to be watchdogs. The big plantations on outplanets use them; they patrol. They get poachers."

  Beam said: "Then originally they're not set for one person."

  "No."

  "Then who set this for Heimie? Not a machine tool syndicate."

  "That was done here."

  He straightened up and lifted the portable TV unit. "Let's go. Take me there, where Tirol had it altered."

  For a moment the woman did not respond. Grabbing her arm he hustled her to the door. She gasped and stared at him mutely.

  "Come on," he said, pushing her out into the hall. The portable TV unit bumped against the door as he shut it; he held the unit tight and followed after Ellen Ackers.

  The town was slatternly and run-down, a few retail stores, fuel station, bars and dance halls. It was two hours' flight from Greater New York and it was called Olum.

  "Turn right," Ellen said listlessly. She gazed out at the neon signs and rested her arm on the window sill of the ship.

  They flew above warehouses and deserted streets. Lights were few. At an intersection Ellen nodded and he set the ship down on a roof.

  Below them was a sagging, fly-specked wooden frame store. A peeling sign was propped up in the window:

  FULTON BROTHERS

  locksmiths

  With the sign were doorknobs, locks, keys, saws, and spring-wound alarm clocks. Somewhere in the interior of the store a yellow night light burned fitfully.

  "This way," Ellen said. She stepped from the ship and made her way down a flight of rickety wooden stairs. Beam laid the portable TV unit on the floor of the ship, locked the doors, and then followed after the woman. Holding onto the railing, he descended to a back porch on which were trash cans and a pile of sodden newspapers tied with string. Ellen was unlocking a door and feeling her way inside.

  First he found himself in a musty, cramped storeroom. Pipe and rolls of wire and sheets of metal were heaped everywhere; it was like a junkyard. Next came a narrow corridor and then he was standing in the entrance of a workshop. Ellen reached overhead and groped to find the hanging string of a light. The light clicked on. To the right was a long and littered workbench with a hand grinder at one end, a vise, a keyhole saw; two wooden stools were before the bench and half-assembled machinery was stacked on the floor in no apparent order. The workshop was chaotic, dusty, and archaic. On the wall was a threadbare blue coat hung from a nail: the workcoat of a machinist.

  "Here," Ellen said, with bitterness. "This is where Paul had it brought. This outfit is owned by the Tirol organization; this whole slum is part of their holdings."

  Beam walked to the bench. "To have altered it," he said, "Tirol must have had a plate of Heimie's neural pattern." He overturned a heap of glass jars; screws and washers poured onto the pitted surface of the bench.

  "He got it from Heimie's door," Ellen said. "He had Heimie's lock analyzed and Heimie's pattern inferred from the setting of the tumblers."

  "And he had the M opened?"

  "There's an old mechanic," Ellen said. "A little dried-up old man; he runs this shop. Patrick Fulton. He installed the bias on the M."

  "A bias," Beam said, nodding.

  "A bias against killing people. Heimie was the exception, for everybody else it took its protective form. Out in the wilds they would have set it for something else, not a TV unit." She laughed, a sudden ripple close to hysteria. "Yes, that would have looked odd, it sitting out in a forest somewhere, a TV unit. They would have made it into a rock or a stick."

  "A rock," Beam said. He could imagine it. The M waiting, covered with moss, waiting for months, years, and then weathered and corroded, finally picking up the presence of a human being. Then the M ceasing to be a rock, becoming, in a quick blur of motion, a box one foot wide and two feet long. An oversized cracker box that started forward--

  But there was something missing. "The fakery," he said. "Emitting flakes of paint and hair and tobacco. How did that come in?"

  In a brittle voice Ellen said: "The landowner murdered the poacher, and he was culpable in the eyes of the law. So the M left clues. Claw marks. Animal blood. Animal hair."

  "God," he said, revolted. "Killed by an animal."

  "A bear, a wildcat--whatever was indigenous, it varied. The predator of the region, a natural death." With her toe she touched a cardboard carton under the workbench. "It's in there, it used to be, anyhow. The neural plate, the transmitter, the discarded parts of the M, the schematics."

  The carton had been a shipping container for power packs. Now the packs were gone, and in their place was a carefully-wrapped inner box, sealed against moisture and insect infestation. Beam tore away the metal foil and saw that he had found what he wanted. He gingerly carried the contents out and spread them on the workbench among the soldering irons and drills.

  "It's all there," Ellen said, without emotion.

  "Maybe," he said, "I can leave you out of this. I can take this and the TV unit to Ackers and try it without your testimony."

  "Sure," she said wearily.

  "What are you going to do?"

  "Well," she said, "I can't go back to Paul, so I guess there's not much I can do."

  "The blackmail bit was a mistake," he said.

  Her eyes glowed. "Okay."

  "If he releases Lantano," Beam said, "he'll be asked to resign. Then he'll probably give you your divorce, it won't be important to him one way or another."

  "I--" she began. And then she stopped. Her face seemed to fade, as if the color and texture of her flesh was vanishing from within. She lifted one hand and half-turned, her mouth open and the sentence still unfinished.

  Beam, reaching, slapped the overhead light out; the workroom winked into darkness. He had heard it too, had heard it at the same time as Ellen Ackers. The rickety outside porch had creaked and now the slow, ponderous motion was past the storeroom and into the hall.

  A heavy man, he thought. A slow-moving man, sleepy, making his way step by step, his eyes almost shut, his great body sagging beneath his suit. Beneath, he thought, his expensive tweed suit. In the darkness the man's shape was looming; Beam could not see it but he could sense it there, filling up the doorway as it halted. Boards creaked under its weight. In a daze he wondered if Ackers already knew, if his order had already been rescinded. Or had the man got out on his own, worked through his own organization?

  The man, starting forward again, spoke in a deep, husky voice. "Ugh," Lantano said. "Damn it."

  Ellen began to shriek. Beam still did not realize what it was; he was still fumbling for the light and wondering stupidly why it did not come on. He had smashed the bulb, he realized. He lit a match; the match went out and he grabbed for Ellen Ackers' cigarette lighter. It was in her purse, and it took him an agonized second to get it out.

  The unreconstructed M was approaching them slowly, one receptor stalk extended. Again it halted, swiveled to the left until it was facing the workbench. It was not now in the shape of a portable TV unit; it had retaken its cracker-box shape.

  "The plate," Ellen Ackers whispered. "It responded to the plate."

  The M had been roused by Heimie Rosenburg's looking for it. But Beam still felt the presence of David Lantano. The big man was still here in the room; the sense of heaviness, the proximity of weight and ponderousness had arrived with the machine, as it moved, sketching Lantano's existence. As he fixedly watched, the machine produced a fragment of cloth fabric and pressed it into a nearby heap of grid-mesh.
Other elements, blood and tobacco and hair, were being produced, but they were too small for him to see. The machine pressed a heel mark into the dust of the floor and then projected a nozzle from its anterior section.

  Her arm over her eyes, Ellen Ackers ran away. But the machine was not interested in her; revolving in the direction of the workbench it raised itself and fired. An explosive pellet, released by the nozzle, traveled across the workbench and entered the debris heaped across the bench. The pellet detonated; bits of wire and nails showered in particles.

  Heimie's dead, Beam thought, and went on watching. The machine was searching for the plate, trying to locate and destroy the synthetic neural emission. It swiveled, lowered its nozzle hesitantly, and then fired again. Behind the workbench, the wall burst and settled into itself.

  Beam, holding the cigarette lighter, walked toward the M. A receptor stalk waved toward him and the machine retreated. Its lines wavered, flowed, and then painfully reformed. For an interval, the device struggled with itself; then, reluctantly, the portable TV unit again became visible. From the machine a high-pitched whine emerged, an anguished squeal. Conflicting stimuli were present; the machine was unable to make a decision.

  The machine was developing a situation neurosis and the ambivalence of its response was destroying it. In a way its anguish had a human quality, but he could not feel sorry for it. It was a mechanical contraption trying to assume a posture of disguise and attack at the same time; the breakdown was one of relays and tubes, not of a living brain. And it had been a living brain into which it had fired its original pellet. Heimie Rosenburg was dead, and there were no more like him and no possibility that more could be assembled. He went over to the machine and nudged it onto its back with his foot.

  The machine whirred snake-like and spun away. "Ugh, damn it!" it said. It showered bits of tobacco as it rolled off; drops of blood and flakes of blue enamel fell from it as it disappeared into the corridor. Beam could hear it moving about, bumping into the walls like a blind, damaged organism. After a moment he followed after it.

  In the corridor, the machine was traveling in a slow circle. It was erecting around itself a wall of particles: cloth and hairs and burnt matches and bits of tobacco, the mass cemented together with blood.

  "Ugh, damn it," the machine said in its heavy masculine voice. It went on working, and Beam returned to the other room.

  "Where's a phone?" he said to Ellen Ackers.

  She stared at him vacantly.

  "It won't hurt you," he said. He felt dull and worn-out. "It's in a closed cycle. It'll go on until it runs down."

  "It went crazy," she said. She shuddered.

  "No," he said. "Regression. It's trying to hide."

  From the corridor the machine said, "Ugh. Damn it." Beam found the phone and called Edward Ackers.

  Banishment for Paul Tirol meant first a procession of bands of darkness and then a protracted, infuriating interval in which empty matter drifted randomly around him, arranging itself into first one pattern and then another.

  The period between the time Ellen Ackers attacked him and the time banishment sentence had been pronounced was vague and dim in his mind. Like the present shadows, it was hard to pin down.

  He had--he thought--awakened in Ackers' apartment. Yes, that was it; and Leroy Beam was there, too. A sort of transcendental Leroy Beam who hovered robustly around, arranging everybody in configurations of his choice. A doctor had come. And finally Edward Ackers had shown up to face his wife and the situation.

  Bandaged, and on his way into Interior, he had caught a glimpse of a man going out. The ponderous, bulbous shape of David Lantano, on his way home to his luxurious stone mansion and acre of grass.

  At sight of him Tirol had felt a goad of fear. Lantano hadn't even noticed him; an acutely thoughtful expression on his face, Lantano padded into a waiting car and departed.

  "You have one thousand dollars," Edward Ackers was saying wearily, during the final phase. Distorted, Ackers' face bloomed again in the drifting shadows around Tirol, an image of the man's last appearance. Ackers, too, was ruined, but in a different way. "The law supplies you with one thousand dollars to meet your immediate needs, also you'll find a pocket dictionary of representative out-system dialects."

  Ionization itself was painless. He had no memory of it; only a blank space darker than the blurred images on either side.

  "You hate me," he had declared accusingly, his last words to Ackers. "I destroyed you. But... it wasn't you." He had been confused. "Lantano. Maneuvered but not. How? You did ..."

  But Lantano had had nothing to do with it. Lantano had shambled off home, a withdrawn spectator throughout. The hell with Lantano. The hell with Ackers and Leroy Beam and--reluctantly--the hell with Mrs. Ellen Ackers.

  "Wow," Tirol babbled, as his drifting body finally collected physical shape. "We had a lot of good times ... didn't we, Ellen?"

  And then a roaring hot field of sunlight was radiating down on him. Stupefied, he sat slumped over, limp and passive. Yellow, scalding sunlight... everywhere. Nothing but the dancing heat of it, blinding him, cowing him into submission.

  He was sprawled in the middle of a yellow clay road. To his right was a baking, drying field of corn wilted in the midday heat. A pair of large, disreputable-looking birds wheeled silently overhead. A long way off was a line of blunted hills: ragged troughs and peaks that seemed nothing more than heaps of dust. At their base was a meager lump of man-made buildings.

  At least he hoped they were man-made.

  As he climbed shakily to his feet, a feeble noise drifted to his ears. Coming down the hot, dirty road was a car of some sort. Apprehensive and cautious, Tirol walked to meet it.

  The driver was human, a thin, almost emaciated youth with pebbled black skin and a heavy mass of weed-colored hair. He wore a stained canvas shirt and overalls. A bent, unlit cigarette hung from his lower lip. The car was a combustion-driven model and had rolled out of the twentieth century; battered and twisted, it rattled to a halt as the driver critically inspected Tirol. From the car's radio yammered a torrent of tinny dance music.

  "You a tax collector?" the driver asked.

  "Certainly not," Tirol said, knowing the bucolic hostility toward tax collectors. But--he floundered. He couldn't confess that he was a banished criminal from Earth; that was an invitation to be massacred, usually in some picturesque way. "I'm an inspector," he announced, "Department of Health."

  Satisfied, the driver nodded. "Lots of scuttly cutbeede, these days. You fellows got a spray, yet? Losing one crop after another."

  Tirol gratefully climbed into the car. "I didn't realize the sun was so hot," he murmured.

  "You've got an accent," the youth observed, starting up the engine. "Where you from?"

  "Speech impediment," Tirol said cagily. "How long before we reach town?"

  "Oh, maybe an hour," the youth answered, as the car wandered lazily forward.

  Tirol was afraid to ask the name of the planet. It would give him away. But he was consumed with the need to know. He might be two star-systems away or two million; he might be a month out of Earth or seventy years. Naturally, he had to get back; he had no intention of becoming a sharecropper on some backwater colony planet.

  "Pretty swip," the youth said, indicating the torrent of noxious jazz pouring from the car radio. "That's Calamine Freddy and his Woolybear Creole Original Band. Know that tune?"

  "No," Tirol muttered. The sun and dryness and heat made his head ache, and he wished to God he knew where he was.

  The town was miserably tiny. The houses were dilapidated; the streets were dirt. A kind of domestic chicken roamed here and there, pecking in the rubbish. Under a porch a bluish quasi-dog lay sleeping. Perspiring and unhappy, Paul Tirol entered the bus station and located a schedule. A series of meaningless entries flashed by: names of towns. The name of the planet, of course, was not listed.

  "What's the fare to the nearest port?" he asked the indolent official behind the ticket
window.

  The official considered. "Depends on what sort of port you want. Where you planning to go?"

  "Toward Center," Tirol said. "Center" was the term used in out-systems for the Sol Group.

  Dispassionately, the official shook his head. "No inter-system port around here."

  Tirol was baffled. Evidently, he wasn't on the hub planet of this particular system. "Well," he said, "then the nearest interplan port."

  The official consulted a vast reference book. "You want to go to which system-member?"

  "Whichever one has the inter-system port," Tirol said patiently. He would leave from there.

  "That would be Venus."

  Astonished, Tirol said: "Then this system--" He broke off, chagrined, as he remembered. It was the parochial custom in many out-systems, especially those a long way out, to name their member planets after the original nine. This one was probably called "Mars" or "Jupiter" or "Earth," depending on its position in the group. "Fine," Tirol finished. "One-way ticket to--Venus."

  Venus, or what passed for Venus, was a dismal orb no larger than an asteroid. A bleak cloud of metallic haze hung over it, obscuring the sun. Except for mining and smelting operations the planet was deserted. A few dreary shacks dotted the barren countryside. A perpetual wind blew, scattering debris and trash.

  But the inter-system port was here, the field which linked the planet to its nearest star-neighbor and, ultimately, with the balance of the universe. At the moment a giant freighter was taking ore.

  Tirol entered the ticket office. Spreading out most of his remaining money he said: "I want a one-way ticket taking me toward Center. As far as I can go."

  The clerk calculated. "You care what class?"

  "No," he said, mopping his forehead.

  "How fast?"

  "No."

  The clerk said: "That'll carry you as far as the Betelgeuse System."

  "Good enough," Tirol said, wondering what he did then. But at least he could contact his organization from there; he was already back in the charted universe. But now he was almost broke. He felt a prickle of icy fear, despite the heat.
