"Ackers," Ackers said.

  "Okay, Ackers. I thought I recognized you, but I wasn't sure; didn't want to make a fool of myself. When was Heimie killed?"

  Grudgingly, Ackers gave him the pertinent information.

  For a time Lantano was silent. Then, slowly, gravely, he said: "You better look at those seven cards again. One of those fellows isn't in the Sirius System… he's back here."

  Ackers calculated the chances of successfully banishing a man of David Lantano's importance. His organization – Interplay Export – had fingers all over the galaxy; there'd be search crews going out like bees. But nobody went out banishment distance. The condemned, temporarily ionized, rendered in terms of charged particles of energy, radiated outward at the velocity of light. This was an experimental technique that had failed; it worked only one way.

  "Consider," Lantano said thoughtfully. "If I was going to kill Heimie – would I do it myself? You're not being logical, Ackers. I'd send somebody." He pointed a fleshy finger at Ackers. "You imagine I'd risk my own life? I know you pick up everybody… you usually turn up enough specifications."

  "We have ten on you," Ackers said briskly.

  "So you're going to banish me?"

  "If you're guilty, you'll have to face banishment like anyone else. Your particular prestige has no bearing."

  Nettled, Ackers added, "Obviously, you'll be released. You'll have plenty of opportunity to prove your innocence; you can question each of the ten specifications in turn."

  He started to go on and describe the general process of court procedure employed in the twenty-first century, but something made him pause. David Lantano and his chair seemed to be gradually sinking into the floor. Was it an illusion? Blinking, Ackers rubbed his eyes and peered. At the same time, one of the policemen yelped a warning of dismay; Lantano was quietly leaving them.

  "Come back!" Ackers demanded; he leaped forward and grabbed hold of the chair. Hurriedly, one of his men shorted out the power supply of the building; the chair ceased descending and groaned to a halt. Only Lantano's head was visible above the floor level. He was almost entirely submerged in a concealed escape shaft.

  "What seedy, useless – " Ackers began.

  "I know," Lantano admitted, making no move to drag himself up. He seemed resigned; his mind was again off in clouds of contemplation. "I hope we can clear all this up. Evidently I'm being framed. Tirol got somebody who looks like me, somebody to go in and murder Heimie."

  Ackers and the police crew helped him up from his depressed chair. He gave no resistance; he was too deep in his brooding.

  The cab let Leroy Beam off in front of the bar. To his right, in the next block, was the Interior Building… and, on the sidewalk, the opaque blob that was Harvey Garth's propaganda booth.

  Entering the bar, Beam found a table in the back and seated himself. Already he could pick up the faint, distorted murmur of Garth's reflections. Garth, speaking to himself in a directionless blur, was not yet aware of him.

  "Banish it," Garth was saying. "Banish all of them. Bunch of crooks and thieves." Garth, in the miasma of his booth, was rambling vitriolically.

  "What's going on?" Beam asked. "What's the latest?"

  Garth's monologue broke off as he focussed his attention on Beam. "You in there? In the bar?"

  "I want to find out about Heimie's death."

  "Yes," Garth said. "He's dead; the files are moving, kicking out cards."

  "When I left Heimie's apartment," Beam said, "they had turned up six specifications." He punched a button on the drink selector and dropped in a token.

  "That must have been earlier," Garth said; "they've got more."

  "How many?"

  "Ten in all."

  Ten. That was usually enough. And all ten of them laid out by a robot device… a little procession of hints strewn along its path: between the concrete side of the building and the dead body of Heimie Rosenburg.

  "That's lucky," he said speculatively. "Helps out Ackers."

  "Since you're paying me," Garth said, "I'll tell you the rest. They've already gone out on their pick-up: Ackers went along."

  Then the device had been successful. Up to a point, at least. He was sure of one thing: the device should have been out of the apartment. Tirol hadn't known about Heimie's death rattle; Heimie had been wise enough to do the installation privately.

  Had the rattle not brought persons into the apartment, the device would have scuttled out and returned to Tirol. Then, no doubt, Tirol would have detonated it. Nothing would remain to indicate that a machine could lay down a trail of synthetic clues: blood type, fabric, pipe tobacco, hair… all the rest, and all spurious.

  "Who's the pick-up on?" Beam asked.

  "David Lantano."

  Beam winced. "Naturally. That's what the whole thing's about; he's being framed!"

  Garth was indifferent; he was a hired employee, stationed by the pool of independent researchers to siphon information from the Interior Department. He had no actual interest in politics; his Banish It! was sheer window-dressing.

  "I know it's a frame," Beam said, "and so does Lantano. But neither of us can prove it… unless Lantano has an absolutely airtight alibi."

  "Banish it," Garth murmured, reverting to his routine. A small group of late-retiring citizens had strolled past his booth, and he was masking his conversation with Beam. The conversation, directed to the one listener, was inaudible to everyone else; but it was better not to take risks. Sometimes, very close to the booth, there was an audible feedback of the signal.

  Hunched over his drink, Leroy Beam contemplated the various items he could try. He could inform Lantano's organization, which existed relatively intact… but the result would be epic civil war. And, in addition, he didn't really care if Lantano was framed; it was all the same to him. Sooner or later one of the big slavers had to absorb the other: cartel is the natural conclusion of big business. With Lantano gone, Tirol would painlessly swallow his organization; everybody would be working at his desk as always.

  On the other hand, there might someday be a device – now half-completed in Tirol's basement – that left a trail of Leroy Beam clues. Once the idea caught on, there was no particular end.

  "And I had the damn thing," he said fruitlessly. "I hammered on it for five hours. It was a TV unit, then, but it was still the device that killed Heimie."

  "You're positive it's gone?"

  "It's not only gone – it's out of existence. Unless she wrecked the car driving Tirol home."

  "She?" Garth asked.

  "The woman." Beam pondered. "She saw it. Or she knew about it; she was with him." But, unfortunately, he had no idea who the woman might be.

  "What'd she look like?" Garth asked.

  "Tall, mahogany hair. Very nervous mouth."

  "I didn't realize she was working with him openly. They must have really needed the device." Garth added: "You didn't identify her? I guess there's no reason why you should; she's kept out of sight."

  "Who is she?"

  "That's Ellen Ackers."

  Beam laughed sharply. "And she's driving Paul Tirol around?"

  "She's – well, she's driving Tirol around, yes. You can put it that way."

  "How long?"

  "I thought you were in on it. She and Ackers split up; that was last year. But he wouldn't let her leave; he wouldn't give her a divorce. Afraid of the publicity. Very important to keep up respectability… keep the shirt fully stuffed."

  "He knows about Paul Tirol and her?"

  "Of course not. He knows she's – spiritually hooked up. But he doesn't care… as long as she keeps it quiet. It's his position he's thinking about."

  "If Ackers found out," Beam murmured. "If he saw the link between his wife and Tirol… he'd ignore his ten interoffice memos. He'd want to haul in Tirol. The hell with the evidence; he could always collect that later." Beam pushed away his drink; the glass was empty anyhow. "Where is Ackers?"

  "I told you. Out at Lantano's place, pick
ing him up."

  "He'd come back here? He wouldn't go home?"

  "Naturally he'd come back here." Garth was silent a moment. "I see a couple of Interior vans turning into the garage ramp. That's probably the pick-up crew returning."

  Beam waited tensely. "Is Ackers along?"

  "Yes, he's there. Banish It!" Garth's voice rose in stentorian frenzy. "Banish the system of Banishment! Root out the crooks and pirates!"

  Sliding to his feet, Beam left the bar.

  A dull light showed in the rear of Edward Ackers' apartment: probably the kitchen light. The front door was locked. Standing in the carpeted hallway, Beam skillfully tilted with the door mechanism. It was geared to respond to specific neural patterns: those of its owners and a limited circle of friends. For him there was no activity.

  Kneeling down, Beam switched on a pocket oscillator and started sine wave emission. Gradually, he increased the frequency. At perhaps 150,000 cps the lock gui ltily clicked; that was all he needed. Switching the oscillator off, he rummaged through his supply of skeleton patterns until he located the closet cylinder. Slipped into the turret of the oscillator, the cylinder emitted a synthetic neural pattern close enough to the real thing to affect the lock.

  The door swung open. Beam entered.

  In half-darkness the living room seemed modest and tasteful. Ellen Ackers was an adequate housekeeper. Beam listened. Was she home at all? And if so, where? Awake? Asleep?

  He peeped into the bedroom. There was the bed, but nobody was in it.

  If she wasn't here she was at Tirol's. But he didn't intend to follow her; this was as far as he cared to risk.

  He inspected the dining room. Empty. The kitchen was empty, too. Next came an upholstered general-purpose rumpus room; on one side was a gaudy bar and on the other a wall-to-wall couch. Tossed on the couch was a woman's coat, purse, gloves. Familiar clothes: Ellen Ackers had worn them. So she had come here after leaving his research lab.

  The only room left was the bathroom. He fumbled with the knob; it was locked from the inside. There was no sound, but somebody was on the other side of the door. He could sense her in there.

  "Ellen," he said, against the panelling. "Mrs. Ellen Ackers; is that you?"

  No answer. He could sense her not making any sound at all: a stifled, frantic silence.

  While he was kneeling down, fooling with his pocketful of magnetic lock-pullers, an explosive pellet burst through the door at head level and splattered into the plaster of the wall beyond.

  Instantly the door flew open; there stood Ellen Ackers, her face distorted with fright. One of her husband's government pistols was clenched in her small, bony hand. She was less than a foot from him. Without getting up, Beam grabbed her wrist; she fired over his head, and then the two of them deteriorated into harsh, labored breathing.

  "Come on," Beam managed finally. The nozzle of the gun was literally brushing the top of his head. To kill him, she would have to pull the pistol back against her. But he didn't let her; he kept hold of her wrist until finally, reluctantly, she dropped the gun. It clattered to the floor and he got stiffly up.

  "You were sitting down," she whispered, in a stricken, accusing voice.

  "Kneeling down: picking the lock. I'm glad you aimed for my brain." He picked up the gun and succeeded in getting it into his overcoat pocket; his hands were shaking.

  Ellen Ackers gazed at him starkly; her eyes were huge and dark, and her face was an ugly white. Her skin had a dead cast, as if it were artificial, totally dry, thoroughly sifted with talc. She seemed on the verge of hysteria; a harsh, muffled shudder struggled up inside her, lodging finally in her throat. She tried to speak but only a rasping noise came out.

  "Gee, lady," Beam said, embarrassed. "Come in the kitchen and sit down."

  She stared at him as if he had said something incredible or obscene or miraculous; he wasn't sure which.

  "Come on." He tried to take hold of her arm but she jerked frantically away. She had on a simple green suit, and in it she looked very nice; a little too thin and terribly tense, but still attractive. She had on expensive earrings, an imported stone that seemed always in motion… but otherwise her outfit was austere.

  "You – were the man at the lab," she managed, in a brittle, choked voice.

  "I'm Leroy Beam. An independent." Awkwardly guiding her, he led her into the kitchen and seated her at the table. She folded her hands in front of her and studied them fixedly; the bleak boniness of her face seemed to be increasing rather than receding. He felt uneasy.

  "Are you all right?" he asked.

  She nodded.

  "Cup of coffee?" He began searching the cupboards for a bottle of Venusian-grown coffee substitute. While he was looking, Ellen Ackers said tautiy: "You better go in there. In the bathroom. I don't think he's dead, but he might be."

  Beam raced into the bathroom. Behind the plastic shower curtain was an opaque shape. It was Paul Tirol, lying wadded up in the tub, fully clothed. He was not dead but he had been struck behind the left ear and his scalp was leaking a slow, steady trickle of blood. Beam took his pulse, listened to his breathing, and then straightened up.

  At the doorway Ellen Ackers materialized, still pale with fright. "Is he? Did I kill him?"

  "He's fine."

  Visibly, she relaxed. "Thank God. It happened so fast – he stepped ahead of me to take the M inside his place, and then I did it. I hit him as lightly as I could. He was so interested in it… he forgot about me." Words spilled from her, quick, jerky sentences, punctuated by rigid tremors of her hands. "I lugged him back in the car and drove here; it was all I could think of."

  "What are you in this for?"

  Her hysteria rose in a spasm of convulsive muscle-twitching. "It was all planned – I had everything worked out. As soon as I got hold of it I was going to -" She broke off.

  "Blackmail Tirol?" he asked, fascinated.

  She smiled weakly. "No, not Paul. It was Paul who gave me the idea… it was his first idea, when his researchers showed him the thing. The M, he calls it. M stands for machine. He means it can't be educated, morally corrected."

  Incredulous, Beam said: "You were going to blackmail your husband."

  Ellen Ackers nodded. "So he'd let me leave."

  Suddenly Beam felt sincere respect for her. "My God – the rattle. Heimie didn't arrange that; you did. So the device would be trapped in the apartment."

  "Yes," she agreed. "I was going to pick it up. But Paul showed up with other ideas; he wanted it, too."

  "What went haywire? You have it, don't you?"

  Silently she indicated the linen closet. "I stuffed it away when I heard you."

  Beam opened the linen closet. Resting primly on the neatly-folded towels was a small, familiar, portable TV unit.

  "It's reverted," Ellen said, from behind him, in an utterly defeated monotone. "As soon as I hit Paul it changed. For half an hour I've been trying to get it to shift. It won't. It'll stay that way forever."

  III

  Beam went to the telephone and called a doctor. In the bathroom, Tirol groaned and feebly thrashed his arms. He was beginning to return to consciousness.

  "Was that necessary?" Ellen Ackers demanded. "The doctor – did you have to call?"

  Beam ignored her. Bending, he lifted the portable TV unit and held it in his hands; he felt its weight move up his arms like a slow, leaden fatigue. The ultimate adversary, he thought; too stupid to be defeated. It was worse than an animal. It was a rock, solid and dense, lacking all qualities. Except, he thought, the quality of determination. It was determined to persist, to survive; a rock with will. He felt as if he were holding up the universe, and he put the unreconstructed M down.

  From behind him Ellen said: "It drives you crazy." Her voice had regained tone. She lit a cigarette with a silver cigarette lighter and then shoved her hands in the pockets of her suit.

  "Yes," he said.

  "There's nothing you can do, is there? You tried to get it open before. They'll
patch Paul up, and he'll go back to his place, and Lantano will be banished -" She took a deep shuddering breath. "And the Interior Department will go on as always."

  "Yes," he said. Still kneeling, he surveyed the M. Now, with what he knew, he did not waste time struggling with it. He considered it impassively; he did not even bother to touch it.

  In the bathroom, Paul Tirol was trying to crawl from the tub. He slipped back, cursed and moaned, and started his laborious ascent once again.

  "Ellen?" his voice quavered, a dim and distorted sound, like dry wires rubbing.

  "Take it easy," she said between her teeth; not moving she stood smoking rapidly on her cigarette.

  "Help me, Ellen," Tirol muttered. "Something happened to me… I don't remember what. Something hit me."

  "He'll remember," Ellen said.

  Beam said: "I can take this thing to Ackers as it is. You can tell him what it's for – what it did. That ought to be enough; he won't go through with Lantano."

  But he didn't believe it, either. Ackers would have to admit a mistake, a basic mistake, and if he had been wrong to pick up Lantano, he was ruined. And so, in a sense, was the whole system of delineation. It could be fooled; it had been fooled. Ackers was rigid, and he would go right on in a straight line: the hell with Lantano. The hell with abstract justice. Better to preserve cultural continuity and keep society running on an even keel.

  "Tirol's equipment," Beam said. "Do you know where it is?"

  She shrugged wildly. "What equipment?"

  "This thing – " he jabbed at the M – "was made somewhere."

  "Not here, Tirol didn't make it."

  "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."
