  Choke Chain

  by Robert Silverberg

  Author’s preface

  It was the busy month of February, 1956. I was four months away from graduation at Columbia, but by now I was selling stories all over the place, and I was going to classes only when absolutely necessary, spending most of my time holed up in my little room on West 114th St. turning out new material, singly or in collaboration with Randall Garrett. We had sold a second and then a third “Robert Randall” novelet in our series to John Campbell, I had placed stories of my own with Campbell, Bob Lowndes, Larry Shaw, and several other editors, and there was the monthly task of meeting my quota for Howard Browne’s two magazines.

  Hardly had I finished “Guardian of the Crystal Gate” for Howard and sold him the “Ralph Burke” story “Stay Out of My Grave,” but I was at work on an 8000-worder that I called “The Price of Air” for him. It saw print in the December, 1956 issue of Fantastic. By then Howard Browne had resigned from Ziff-Davis so he could return to writing mystery novels, and the new editor was Howard’s former associate, Paul Fairman, a much less jovial man with whom I never attained much of a rapport. Fairman kept me on as a staff writer, but it was strictly a business matter, whereas I think the amiable Howard Browne had regarded me as something of an office mascot.

  When he published “The Price of Air,” Fairman changed the title to “Choke Chain,” which puzzled me, because I didn’t know what the term meant. Later I discovered that it’s a dog-owner thing. I am a cat-owning sort of person. It is, I suppose, an appropriate enough title for this story, and I have left it in place this time around.

  Callisto was supposed to have been just a lark for me, a pleasant stopoff where I could kill time and work up the courage to tackle the big task—Jupiter. I felt that exploring the big, heavy planet was, well, maybe not so grand a thing as my destiny, but yet something I had to do.

  There was only one trouble: the immenseness of Jupiter’s unknown wastes scared me. Fear was a new sensation for me. I got as far as Jupiter’s moon Ganymede, a thriving world bigger than Mercury, and suddenly, with great Jupiter looming overhead in the sky like a bloated overripe tomato, I knew I wasn’t ready for it. I’ve been to a lot of places and done a lot of things, and this was the first time I’d ever drawn back from an adventure.

  I dallied on Ganymede for a couple of days, not knowing quite where to turn. Then one night in a bar someone hinted to me that something funny might be going on on Jupiter’s largest moon, Callisto, and I set my sights there.

  It seemed Callisto had recently clamped down on tourists, had booted out a couple of newspapermen, and had done some other mighty peculiar things, and rumors were spreading wildly about what might be taking place there.

  It looked like a fine idea, at the time: go to Callisto, find out what the trouble was, spend a few days putting things in order. It was the kind of jaunt I thrive on, the sort of thing that’s been my specialty since I began roaming the spaceways. By the time I was through on Callisto, I thought I’d have the blood flowing smoothly in my veins again, and I’d feel more like tackling the Big Project: Jupiter.

  Only Callisto wasn’t the picnic I thought it would be. It turned out to be something more than a refresher for weary adventurers. I found that out as soon as I got there.

  It had been rough to get a passport, but I finally signed on a slow tug as a mechanic, and that was good enough to get me a landing permit for Callisto.

  I helped pilot a tugload of heavy crates from Ganymede to its nearby twin moon, Callisto. I didn’t know what was in the crates, I didn’t ask, and I didn’t care. The job was getting me to the place I wanted to get to, and that was what counted.

  We reached the satellite in a couple of days, and the skipper put the ship down in a vast, windswept desert of blue-white ammonia snow. As soon as we were down, the captain radioed Callisto City to let them know we were here.

  Callisto City is a giant dome, a plastine bubble that covers a fair-sized chunk of Callisto and houses several tens of thousands of colonists. We were outside it, in the snow.

  I waited impatiently, staring out the port of the ship at the empty swirls of snow, watching a little convoy of trucks come crawling out of Callisto City like so many black bugs and go rolling through the snow to meet us.

  Then they arrived. A gong sounded, and I heard the captain yell, “Into your spacesuits, on the double! Let’s get the cargo loaded extra quick.”

  We suited up, and by that time the trucks had arrived. We loaded our cargo aboard them, and one by one they started back to the dome. That was all there was to it. No contact between Callistans and outsiders at all.

  When the last crate was swung aboard the last truck, the captain said, “Get back in and let’s blast off!”

  I turned to him. “I’m not going. I’m resigning, sir.”

  He looked at me blankly, as if I’d just said, “I’m dead, sir.” Finally he said, “You’re what?”

  I nodded. “I’m quitting? Right here and now. I’m going to grab one of these cargo trucks back to Callisto City.”

  “You can’t leave in the middle of the trip!” he protested. He went on objecting, violently, until I quietly told him he could pocket the rest of my uncollected wages. At that he shut up in a hurry, and gestured for me to get going. These guys are all alike.

  I climbed into the rear truck of the convoy, and the startled driver looked at me wide-eyed.

  “What the hell are you, buddy? There’s nothing about you on my cargo invoice.”

  “I’m just going along for the ride, friend,” I told him softly. “I’m a sightseer. I want to get a look at your fair city.”

  “But you can’t—” he objected. I jabbed him in the ribs, once, in exactly the right place, and he subsided immediately.

  “Okay, buddy,” he grunted. “Lay off. I’ll take you—but remember, it’s only because you forced me.” He wrinkled his brow in puzzlement. “But it’s beyond me why in blazes anyone would want to get to Callisto that bad—when we’d all give our left ears to get away.”

  “It’s my business,” I said.

  “Sure, sure,” he said placatingly, afraid of another poke. “Do whatever you damned please. But it’s your funeral—remember that.”

  I smiled to myself, and watched the shining dome of Callisto City grow nearer. I was wondering what was going on beneath that peaceful-looking arc of plastine. It didn’t sound very good.

  Finally we reached the city, and the truck edged carefully into the airlock. My helmet-window went foggy as the icy air of outside was replaced by the warm atmosphere of Callisto City, and then I saw my fellow truck-drivers climbing down and getting out of their spacesuits, in obvious relief at being able to shuck the bulky, uncomfortable things.

  As I slid out of mine, I noticed one very strange thing. All the truck-drivers—every last one—wore curious golden collars around their necks. The collars were almost like dog-collars, thick, made of what looked like burnished bronze. They seemed oddly flexible and solid at the same time, and set in the middle of each was a little meter that kept clicking away, recording some kind of data.

  I looked around. There were twenty or thirty Callistans near me, and they all wore the collar. And they all wore the same facial expression, too. The best way to describe it is to call it a beaten look. They were all beaten men, spiritless, frightened—of what?

  The intense fluorescent lights from above glinted brightly off the collars. Was wearing them some kind of local custom, I wondered? Or a protection against something?

  I heard low whispering coming from them as they stowed their spacesuits in dull-green lockers ranged along the side of the airlock, and headed back toward their trucks.
They were all looking at me, and obviously they were commenting on the fact that I didn’t have any collar. They seemed shocked at that, and very worried.

  “What’s this collar business?” I asked the driver of my truck, as we moved through the inner lock and into the city proper.

  “You’ll find out, chum. Just make sure you can run fast when they spot you, though.”

  “When who spots me?”

  “The guards, dope. The Tax Agents. You don’t think you can breathe for free on Callisto, do you?”

  “You mean they tax your breathing?” I asked, incredulously, and before I could get an answer I saw a cordon of guards forming around our truck.

  There were half a dozen of them, burly men in blue uniforms, all of them wearing the ubiquitous metal collar. They had halted our truck, which had been last in the procession. I saw the other trucks in the convoy rolling on toward their destination somewhere in the city.

  “Don’t make trouble for me,” my driver said pleadingly. “I’ll be docked if I don’t get my cargo back on time.”

  One of the men in uniform reached up and opened the cab of the truck. “Come on out of there, you.”

  “Who, me?” I asked innocently. “What for?”

  “Don’t play games,” he snapped. “Get out of that truck.” He waved a lethal-looking blaster at me, and I decided not to argue with it. I leaped lightly to the ground, and as I did so the uniformed man signalled to my driver that he could go ahead.

  The six men ringed threateningly around me. “Who are you?” the leader demanded. “Where’d you come from?”

  “That doesn’t matter,” I said belligerently. He put his hand on my arm, and I jerked away. “I’m a tourist. Want to see my landing permit?”

  “Landing permits don’t mean a thing here,” he said. “Where’s your respirometer?”

  “My what?”

  “According to statute 1106A, Book Eleven, Civil Code of the Principality of Callisto City,” he reeled off, “all inhabitants of the Principality of Callisto City are required by law to wear respirometers at all times, whether they are transients or permanent inhabitants.” He finished his spiel and gestured boredly to one of his assistants. “Give him the collar, Mack.”

  The man named Mack opened a wooden box and revealed one of those metal collars, the kind that seemed to be all the rage in Callisto just then. He held it out invitingly.

  “Here you are, dear. The finest model in the house.”

  I drew back. “I don’t want your goddam collar,” I snapped hotly.

  “You’ve heard the regulation,” the head man said. “Either you put the collar on or you turn around and walk out the way you came.”

  I turned and looked through the translucent airlock out at the barren wastes of frozen ammonia. “I’m staying here, for the time being. And I don’t plan on wearing any collars.”

  He frowned. I was being particularly troublesome, and he didn’t like it. He waved his blaster in an offhand gesture. “Put the collar on him, boys.”

  Mack and one of the others advanced toward me, holding the gleaming metal circlet. I took one look at it, smiled, and said, “Okay. I know when I’m licked. I can’t fight all of you.”

  They relaxed visibly. “Good to see you cooperate. Put it on him.”

  I let them come close, and Mack was starting to lower the thing over my head when I went into action. I batted the collar out of his hands and heard it go clanging across the floor, and at the same time I lashed out with my foot and nipped the boss’ blaster right out of his amazed hand. The gun went flying thirty feet or more.

  Then they were all on me at once. I pounded back savagely, feeling solid flesh beneath my knuckles and occasionally the unyielding coldness of someone’s collar as I drove a fist past it into his jaw.

  Some picnic, I thought, as I waded gleefully in, flattening Mack with a poke in the stomach and sending another one reeling to the ground with a swift kick. Luckily for me, the head man had been the only one wearing sidearms—and apparently some street urchin had made off with the blaster before he could find it again, because I wasn’t getting cooked.

  I crashed two of them together, pushed the remaining two aside, and dashed away toward the entrance to the city. I heard them pounding after me in hot pursuit.

  It was about a hundred yards to the edge of the city. I made the dash in a dozen seconds and found myself in a crowded thoroughfare, with a number of people watching my fight with evident interest.

  I broke into the crowd and kept on running, pushing people aside as I went. Behind me, I could see the six policemen jostling their way along. One of them had found another blaster somewhere, but he didn’t dare use it in such a crowd.

  I rounded a corner, nearly slipped, and then doubled back and headed for the main thoroughfare again. The cops weren’t taken in by my maneuver, though, and as I looked back I saw them following grimly, shouting something at me. There were more of them now.

  Suddenly I felt a hand slide into mine, soft and warm, and a gentle voice at my side said, “Come with me.”

  I didn’t argue. I saw the crowd close up into a solid mass behind us, and heard the roaring of my frustrated pursuers, as my unknown rescuer led me away to safety.

  As we ran, I glanced down and saw a girl at my side, with her hand grasping mine. She was about twenty-two, wearing a clinging blue tunic that cut off above her knees. She had copper-red hair, and around her neck was that curious collar.

  After running a block and a half, we came to a small tenement-house of the kind common in Callisto City. “In here,” she whispered, and we ducked inside.

  Then up a flight of stairs, around a corridor, down a dimly-lit hallway. We stood for an anxious moment outside her door, while she fumbled nervously in an attempt to touch her thumb to the doorplate, and then finally she managed to impress her print on the sensitive photoelectronic plate and the door slid noiselessly open.

  We stepped inside, and with a feeling of relief I watched the heavy door roll back. I was safe—for now.

  I turned to the girl. “Who are you? Why’d you bring me here?”

  The run had tired her. Her breasts rose and fell as she gasped for breath, and she smiled and held up a hand for time as she struggled to talk. Finally, panting, she managed to say, “I’m June Knight. I saw the whole scene with the guards. You’re safe here, for a while. But tell me—why have you come to Callisto?”

  “Why does everyone wear these collars?” I countered, ignoring her question.

  Her pretty face grew sad. “They make us—the Three, that is. Come on inside, and I’ll get together something for you to eat. You must be starved, and we can talk later.”

  “No,” I said quickly. “I’m not hungry. I’m more anxious to find out what’s been happening here.”

  “Well, even if you’re not hungry, I am,” she said. “Come into the kitchen and I’ll tell you the whole story—the story of how this whole city’s been enslaved.”

  She went into the adjoining room of the little flat, and I followed her. She punched keys on the robocook, dialing a small but nutritious meal, and when the food was placed before her on the table she turned to me.

  “First,” she said, “when’s the last time any news came from Callisto to the outside world?”

  I shrugged. “I haven’t been keeping up with the news. I’ve been on Mars the last two years, hunting rhuud in the lowlands. The papers don’t get there often.”

  “Oh. You’ve been out of touch. Well, you haven’t missed any news from Callisto, because we’ve had an efficient news blanket in operation for almost a year and a half. And for a while it was a voluntary one—just about two years ago, when the air started going bad. We didn’t want outsiders to know.”

  I blinked. “The air?” In a dome-city like this, the air supply was, of course, wholly artificial, and its proper maintenance was of vital importance to the entire community. “What happened to the air?” I asked.

  “I’m not sure,” she said.
“None of us are. Suddenly it became impure. People began sickening by the hundreds; some died, and almost everyone else was ill in one way or another. A tremendous investigation was held by the people who were our government then—Cleve Coldridge was our mayor, a fine man—and nothing could be determined about the source of the impurities. And then my father—he’s dead now—invented this.” She tapped the metal collar she wore around her throat.

  “And what, may I ask, is that collar?”

  “It’s a filter,” she said. “When the collar is worn, it counteracts the impurities in the air, through some process I don’t understand. My father died shortly after he developed it, and so he didn’t get a chance to offer it to the public. He willed the design and the process to three—friends—of his.” Her mouth clamped together bitterly, and I saw her struggling to fight back tears. Almost automatically, I put my arm around her.

  “I’ll be all right,” she said. “Every time I think of those three, and what they’ve done to Dad’s invention—”

  “Tell me about it later, if you want.”

  “No. You might as well know the whole story. The three of them—Martin Hawkins, an Earthman, Ku Sui, a Martian, and Kolgar Novin, a Venusian—announced my father’s device to the public as if they had discovered it themselves. It was the solution to our air-impurity problem. They started turning out the collars in mass production, and within a month everyone in Callisto City was wearing one.”

  “Did that stop the sickness?”

  She nodded. “Immediately. The hospitals emptied out in no time at all, and there hasn’t been a case of that disease since then.”

  “Is that all?” I asked.

  “Hardly. The trouble didn’t start until after we were all wearing the collars.” She took my hand and guided it along her collar to the back of her neck, where I felt a tiny joint in the metal.

  “What’s that?” I asked.

  “That joint is the weapon those three hold over us at all times. These collars, you see, can be tightened at will by remote control—and my father’s three friends operate the controls!”
