Dyer returned to the Command Room in the early hours of the morning to find that the team had embarked on a game of Musical Feeder Circuits, as Chris called it. The idea was similar to musical chairs and involved trying to juggle the switches in the various control rooms so that the backup stations were all hooked to one set of feeders while Spartacus was left hooked to the rest. Since nobody knew which feeders Spartacus was using, the game was played by getting all the backup stations onto one set and shutting down the others to see what happened. If the "chair" that was suddenly pulled away in this fashion turned out to be the one that Spartacus was sitting on, then it would have lost and everything would be under control again.
Unfortunately it didn't work. Spartacus seemed to have connections to just about every one of the feeders, a suspicion that was confirmed as the hours went by and the reports from Haystack started coming in. There was no way of putting Spartacus down without it taking the backup stations with it.
The statistics accumulated through the night to tell their story of the battle of endurance going on all over Janus between flesh and blood on the one hand, and the tireless drones on the other. The bridges were being cut as fast as they were found but they were being created faster. They were also becoming more elaborate. On top of that, the news from Detroit was that Spartacus had increased its drone-manufacturing schedules substantially, so things were not going to get any easier. Krantz had gone away to rest shortly after midnight and Dyer spent the rest of the night deputizing, which meant working with Linsay's officers to improve the search plans and modify the personnel deployment of Haystack as Spartacus's methods of working became better understood. They had just put out orders to draft more manpower into the operation when Krantz reappeared to resume directing. Dyer updated him on developments and then at last, when by rights the Sun should have been just rising, he announced that he was packing it in.
Fifteen minutes later, bleary-eyed and yawning, he arrived at the subway point below his bungalow in the semirural greenery of Vine County, let himself in the lower-level front door and trudged wearily up the single flight of stairs to the main entrance hallway above. The shoulder wrap draped across two of the coat pegs on the wall and the pocketbook lying on the table told him that Laura was there. He walked quietly into the kitchen, keyed an order for a hot bacon sandwich and a black coffee into the chef, and then went into the bathroom to rinse his face. When he came back into the kitchen his snack was ready. He sat down and began eating slowly, savoring the feeling of his body beginning to unwind while he turned the day's happenings over in his mind.
"Another thing I like about you is the way you always look after your guests." Laura's voice sounded sleepily from the doorway behind him. He realized that he had no idea of how long he had been sitting there. His cup and plate were both empty. He turned his head and managed a tired grin.
"Hi," he said.
Her long, tanned legs disappeared provocatively into a flimsy negligee that just managed to reach the tops of her thighs. Beneath the wisp of material, the ample curves of her body were thrown into tantalizing silhouette by the light from the open doorway of the bedroom behind her. She came into the kitchen, kissed him on the side of the face and sat down on a stool across the corner of the table from him.
"So what's been happening?" she asked. "I haven't heard any bombs dropping yet."
Dyer summarized briefly what had gone on since late the previous evening.
"But so far it's acting smart, but purely passively," he said. "It's restricting itself to devising better ways of responding to power cuts. It hasn't shown any sign yet of conceiving the notion that something outside itself is responsible for the cuts. You can stand right in front of a drone and take a cable out and it won't do anything until the power actually disappears. Then all it'll do is call up its buddies to fix it. Spartacus hasn't connected the cause with the effect yet."
"You mean it still sees the world through wires," Laura said.
"Something like that."
"I thought it saw through drones and things too. How come it's not smart enough to figure out what's doing it?"
"Oh, it's programmed to respond to certain patterns connected with certain procedures, that's all. Before it could do what you said, it'd have to evolve a whole concept of itself existing in a space in which other objects exist as well that can interact with it. It's like it takes a baby time to figure out that there's a world around it and some things in that world are parts of itself and some things aren't."
"Like fise?"
"Uh huh."
"But Spartacus's smarter than fise."
"True, but it's got a hell of a lot more of a complicated world to figure out than fise had."
"I see." Laura fell silent and thought to herself for a while. Dyer shifted his eyes toward her and began tracing the curve of her breast absently with the tip of his finger, slowly circling the point where the hard dark nipple pressed proudly against the material.
"You said 'yet,' " Laura murmured. "Does that mean you think it will?"
Dyer shrugged.
"I'm not sure anyone really knows what to think anymore. After what's been happening tonight I'll believe anything." He slid his hand up to her shoulder and touched her cheek "Let's go to bed."
Laura looked at him in surprise.
"Seriously? You look a little like something that just woke up in a funeral parlor and decided to take a walk."
"Our days might be numbered," he told her as he stood up and slipped an arm around her waist. The lights extinguished themselves as they moved out of the kitchen.
Minutes later he tumbled into a bed that was delightfully warm and felt a cool arm slide itself around his neck. He lay back in the darkness and let the softness of the sheets draw the tension and fatigue out of his body. Laura's body was warm and fragrant beside him, her hand stroking gently on his chest . . . and then sleep hit him like a pile driver.
The viset by his ear was shrieking insistently. Emergency tone! Still semi-comatose he groped for the panel and moved it toward him. It was Krantz.
"Two of the backup stations have just lost power," Krantz said shortly. "The only thing left now that's handling life-support in Sector Two of Detroit and half of Berlin is Spartacus, so we've had to lay off trying to shut it down. You'd better get over here right away."
Dyer was already climbing into his clothes when Laura opened her eyes and blinked herself back to wakefulness.
"What is it?" she asked.
"I don't know. Trouble with the backups. I've gotta go to the CBR. I'll see you sometime later."
Laura sat up and shook her head. "Whatever it is, I'm not missing it. Got time to wait for me to get dressed?"
"Sorry. That was Krantz. He sounded panicky. I'll see you later when you show up." He used the viset to summon a subway car to the pickup point below the house, blew Laura a quick kiss and grabbed his jacket up off the floor. When he arrived at the pickup point and interrogated his viewpad, the display informed him that a car would arrive in thirty seconds.
With the pressure on it increasing steadily as a result of Haystack, Spartacus had been forced to resort to progressively more elaborate means to preserve its power sources. First it began manufacturing multiple-path circuits to enable any of its nodes to draw from more than one of the feeders driven by the fusion plant, and after that it stepped up its production of drones to combat the efforts being redoubled against it.
The commanders of Haystack had spent most of the night studying the unfolding pattern of developments and endeavoring to find ways of using their resources more effectively. So, apparently, had Spartacus. And it found a way of saving itself a lot of time and effort that nobody had even considered. Instead of installing new cables every time it wanted to create a connection between one point and another, it discovered that in many instances there were cables already laid over much of the desired routes—cables which it didn't recognize as forming any part of itself or of the equipment which it controlled. So it did the logical thing and, wherever possible, began disconnecting sections of such "foreign" cables and substituting its own devices at the ends instead. Unfortunately some of these had turned out to be supply lines to the backup stations.
Dyer scanned the reports of the past few hours and digested the gist of them while Krantz finished his summary of what had been happening.
"Obviously we can't let this continue," Krantz said. "The situation is ludicrous! If it gets any worse we'll end up depending solely on Spartacus. If all the backups go, we won't be able to risk touching it without evacuating Janus."
"We've had to order a stop to the bridge cutting," Linsay told Dyer. "Searching is being continued but we're restricting action to concentrating on getting those backup stations restored before anything else. I want to mount a limited version of Counterstrike against any drones that try to interfere with getting the backups live again." He looked expectantly at Krantz.
"We'd like your vote on that," Krantz said to Dyer.
Dyer turned away and let his gaze sweep around the Command Room while he considered the suggestion.
He had to admit that it made sense. With two backup stations down, the safety net that was supposed to provide protection against fault conditions or against Spartacus's ongoing evolution taking a dangerous turn was in shreds. To refrain deliberately from any action that would help get the backup stations running again would be insane. This latest development had taken the whole experiment outside the limits of an Earth-like situation and to cheat a little in order to restore a level of protection that was necessitated only by Janus's isolation would simply be putting things back on their proper footing. He turned back to face the other two again and nodded his head briefly.
"I agree," he told them. "A limited Counterstrike in Sector Two, Detroit and north Berlin only. Minimum force. Jamming and obstruction to be employed exclusively as far as possible. Weapons strictly as a last resort."
While Linsay was translating this into orders to go out to the operational units, Dyer noticed Laura slip in through the main door and walk over to start talking with Chris and Ron. As he did so he was reminded uncomfortably of Al Morrow's antics with Pattie.
"Sometimes the ink's just wasted on the company," he grunted to himself.
At the two locations selected, Counterstrike proved fearsomely effective and within a matter of hours both backup stations were back to normal. In other areas, however, drone activity was allowed to continue unabated and frantic calls soon began coming in to report that the drones were threatening to disrupt other feeder circuits going to other backup stations. Counterstrike had to be extended to include offensive deactivation of all drones attempting to interfere with any backup supply lines anywhere on Janus. By midafternoon the battle to keep the Janus experiment within bounds that meant something was over. It had been won; the backup stations were once more secure. The battle to wrest the fusion plant back from Spartacus could now be resumed.
But the battle of the backup stations had not been fought without cost. The cost had been in time. Ever since the first emergency of the two backups going down early that morning, the active side of Operation Haystack had been suspended, which meant that a watch had been kept on Spartacus's construction of bridges to the fusion grid but no attempt had been made to continue cutting them. The reason for this was that if the engineers happened to hit a lucky combination they might have succeeded in switching Spartacus off, but without the full backup system secure Spartacus was the only system left to maintain habitable conditions in some parts of Janus. Switching Spartacus off in that way and under those conditions would have been equivalent, in effect, to saying that a runaway titan could always be turned off by blowing up Earth. Since that much was patently obvious to everybody anyway, it would have achieved nothing apart from terminating the experiment at the very point where they might start learning something really useful.
So for the best part of a day Spartacus had been able to carry on with its bridge-making without hindrance. The only drones attacked during that period had been the ones attempting to hijack feeder cables that supplied the backup stations. When the scientists finally had time to take stock of things after the backup stations had been secured, they found that Spartacus had made full use of the opportunity.
"I reckon we've lost the initiative," Fred Hayes declared after a lengthy analysis of the statistics. "Spartacus had built up a hell of a lead for itself by this morning. It's been upgrading primaries and getting bigger all the time, and putting in a whole private power network for itself on top of that."
"You don't think we could catch up with it if we put everything into an all-out Haystack effort?" Krantz asked.
"Our prediction is that tomorrow morning we'd be twice as far behind as we were this morning," Dyer answered. "And after that it would go on getting worse exponentially."
"Our estimates about this part were way out. There's no point in denying it," Frank Wescott said, A long silence ensued. Eventually General Linsay spoke.
"Why are we acting as if it's all bad news? Our objective was to find out if we could guarantee that an Earth-sized system like titan could never get out of control permanently. The plan said that if we could stop it by deactivating its drones then we'd still be okay in the end. We could allow titan to grow bigger and know that we'd always have the last say. The benefits would still outweigh the risks because the only real risk that could really hurt us would have gone away . . . or at least, would have been shown to be containable." He shrugged.
"Well, we know we can do that. We've only operated Counterstrike on a limited scale but it worked fine. We had the bastard licked earlier today. Okay, so Haystack isn't the final answer. The plan never said it had to be. It isn't our last card either."
"What are you saying—go all out for Counterstrike?" Krantz asked.
"We have to," Linsay replied. "We've all just agreed that Haystack isn't going to get us anywhere. The machine wants to make a fight out of it for real? Okay, let's give it what it wants."
"What do you say, Ray?" Krantz looked at Dyer.
"He's right," Dyer said. "Haystack will only lose more time that we don't have. We've learned everything from it that it's going to tell us. We'll never cut it off from the grid now while the drones are still active. We know that Spartacus won't respond to system commands to deactivate them anymore, so the only thing to do is get out there and deactivate them ourselves. As Mark says, it worked okay on a small scale, so with luck we should have it licked, maybe by tomorrow." He cocked an inquiring eye at Hayes for a second opinion.
"Mmm . . . to track down all the bridges and cut them . . ." Hayes rubbed his chin, studied his figures and thought for a moment. Then he nodded. "Yes . . . I reckon we could do it in around a day . . . if we get those drones out of the picture now without any messing around."
And so, less than a day after it had been hopefully initiated, Operation Haystack was called off and Linsay ordered a full-scale Counterstrike. All over Janus the various duty crews began preparations for offensive action against any drone found active in the vicinity of a feeder circuit.
But, in limited form, Counterstrike had already been going on for some time.
Spartacus had had almost a day to ponder on the fact that something beyond its control was capable of interfering with the drones, If the something could do that, it could obviously have a big effect on the question of Spartacus's general well-being and long-term future. So, how did the something manage to influence drones, and what was the nature of the something?
