For a third time, the rocket staggered and then caught itself. Yalda felt as if she were back on the footbridge over the trench, paralyzed by the sight of the abyss beneath her—and watching the ropes that supported her snapping one by one. Where were the reports from the machinists? She stared at the bank of paper tape writers connected to the signaling ropes. Though the devices had never been used outside the Peerless, they’d proved invaluable during the construction phase. Only adjacent chambers were connected directly, but messages that needed to go farther could be relayed from chamber to chamber. These particular units had been tested thoroughly—most recently when the machinists had first reached their stations prior to the launch.
Finally, one writer began disgorging a message. Babila could reach it without leaving her bench; she grabbed the end of the strip and peered at it, frowning, before the message was complete. Having the thing print actual symbols would have made it too complicated, so they’d devised and memorized a simple code that could be transmitted by tugging on either of two ropes.
From chamber four, Babila wrote on her palm, stretching her hand to fit more words. Feed stopped. Waiting. Chamber four was out at the rim; the message had reached them via two intermediaries.
That would have been the first failure, with the machinist following the protocol and delaying inspection until the thrust was reduced and movement became easier. But then almost immediately, another message arrived: From chamber three. Feed stopped. Investigating.
Chamber three was also at the rim, right next to chamber four. What source of failure, Yalda wondered, could depend on proximity? Dust from construction rubble—somehow missed in all the inspections—shaken out of its hiding place and rendered airborne by the vibrations?
That made no sense, though. Coarse enough debris might jam the clockwork—delaying the feed’s opening in the first place—but Yalda was sure there was no part of the machinery where grit in the cogs could cause the feed to close once it was already open.
Chamber four, then chamber three… she wasn’t going to wait to learn where the third failure had been. She held up her hand to Babila. Message to chamber two, and all its neighbors: Make a full inspection.
Babila started working the ropes. Frido caught Yalda’s eye.
Sabotage? he asked. His face bore an expression of disbelief. This was not a scenario they’d anticipated.
Just being cautious, she replied. Whatever the cause of the first two failures, it could do no harm to test the assumption that their proximity was more than a coincidence.
Yalda turned to the clock; in a couple of lapses they would reach planetary escape velocity. The protocols dictated that three failures was the limit; one more and she’d have no choice but to shut down all the engines as soon as it was safe and let the Peerless drift around the sun until they’d diagnosed and remedied the problem.
Another of the tape writers started up. This one was out of Babila’s reach; she unstrapped herself and lumbered across the floor, pausing to strengthen her legs with extra flesh from her torso. As she read the message her tympanum twitched, as if she couldn’t stop herself silently cursing. Then she turned away from the machine and wrote across her chest: From chamber two. Intruder sighted. Pursuing.
Yalda and Frido joined her in spreading the news—first to those chambers that were close to number two but where the message would not have been seen already. The rope system was faster than any messenger on foot, but it was beginning to seem hopelessly slow and unwieldy.
When they’d finished Yalda stood beside the tape writers, disoriented and frustrated. An intruder? Accepting the notion was difficult enough, but her role made it even harder to bear. She should have been running through the feed chambers trying to catch the saboteur, not hanging around here playing message clerk.
Six chimes from ignition—precisely on schedule—the other feeds proved that they were operating flawlessly by cutting back the rocket’s thrust from two gravities to one, all the while smoothly maintaining the balancing act compensating for the dead engines. The Peerless was four times as far from the center of the world now than it had been at launch—and moving almost five times faster than it needed to be to continue its ascent indefinitely. To the astronomers tracking their flight from the ground, the journey would appear to be proceeding uneventfully. One more jammed feed, though, and the whole world would have known that they were in trouble.
Yalda tentatively relaxed her tympanum; the hammering of the engines was still unpleasant, but it wasn’t intolerable.
“I think speech is viable again,” she shouted at her companions.
What? Babila wrote on her chest.
Yalda turned to Frido. “So who’s the number one candidate to send in a saboteur?”
Frido’s expression made it clear that he knew who she had in mind, but he still balked at the idea. “Six gross casualties, all innocent people…?”
“If it was Acilio, he wasn’t trying to murder us,” Yalda replied. “If that had been the aim he would have sent someone after the gyroscopes; he could have crashed the Peerless when it was barely off the ground, and made a big display of it for everyone watching from Zeugma.”
“So he wanted us drifting?” Frido suggested. “Demoralised by the engine failures, hanging around in orbit until we’d taken every feed apart and inspected every component a dozen times. Nobody dead, but enough of a setback to humiliate Eusebio.”
“Who’s this Acilio?” Babila asked.
“A Councilor in Zeugma,” Yalda explained wearily. “His grandfather and Eusebio’s grandfather had a business dispute—”
Babila held up a hand to stop her. “I don’t care about anyone’s squabbling ancestors. His name and position should be enough for the people who return to find him and kill him.”
Yalda said, “Yeah, we’re not interested in those barbaric generations-long feuds.”
One of the tape writers sprung to life; Yalda stepped forward and began decoding the message. “From chamber one,” she read. “Intruder captured. Claims he’s alone. Bringing him to you.”
Half a bell later, four machinists entered the navigator’s post. Pia, Delfina and Onesta were walking in single file, carrying their captive on their shoulders; they’d extruded extra arms to hold him in place, but he did not appear to be struggling. The fourth machinist, Severo, was too short to join in the formation, so he walked ahead of the women as a lookout.
The machinists dropped their burden in front of the navigators; the saboteur crouched on the stone, his face turned to the floor. He wasn’t wearing a name tag, but Yalda was almost certain that she recognized him.
“Nino?”
He didn’t reply. She squatted for a better look; it was him. She still remembered handing him his tag before Eusebio’s big speech.
“Why?” she demanded, angry and perplexed. Nino had witnessed Benedetta’s crash, but he had still chosen to stay with them; she’d thought that was a sign of his commitment. “What did Acilio offer you?”
At the mention of the name Nino’s rear eyes flickered toward her, all but confirming her guess. “Is there anyone else here working for him?” she asked.
Nino’s reply was inaudible beneath the noise of the engines. “Speak louder,” Yalda yelled. “Who else did he recruit?”
