“Same here, Peggy, with five shadow lines, and it looks like we agree.” Abby, a tall young woman, had been an alt-tech engineer before Daybreak. Highbotham privately worried that in a fight, Abby’s waist-length ash-blonde ponytail might get her shot for a Daybreaker.
Gilead, slim, dark, at one time a Miami stock analyst, clicked his tongue. “Same spot but with one out of six shadow lines that was a little off. Looks like girls rule today.”
Henry, who had been a math grad student, was nodding too. “On this scale a pencil line is about 667 meters wide. We can’t get any more precise than that with the instruments we have. We’ve got the moon gun nailed.” The hand-whittled frames and hand-ground lenses of his glasses in the moonlight looked like an outsized silver domino mask.
“Unless when we combine all our observations,” Richard said, “it turns out we have it nailed to more than one place.”
“Two pitchers of beer and good meal say the CEP will be less than a click,” Henry said.
“You’re on.”
“Well, now that you all have food and beer riding on it,” Highbotham said, “I know I can trust you with the calculations you’re about to get to.”
The team bent to the job of combining all their observations into one best result with pencil, abacus, adding machine, and slide rule; the process would take till well past dawn.
Highbotham scribbled Morse for a brief radiogram to alert the world that another EMP bomb was coming in, but her pencil stopped after two lines. She stared out to sea, listening hard. Something’s wrong.
She sat back. So why now?
The moon gun launched an EMP weapon to burst over any strong radio source. There were half a dozen hypotheses about how Daybreak had placed it there, but for the foreseeable future those questions were merely interesting. The more significant question was how much the operators, if any, of the moon gun were able to communicate with the leadership, if any, of Daybreak. Arnie Yang’s experiments, before he himself had been seduced by Daybreak, had demonstrated that to some extent it responded to the content of the messages as much as the strength of the signal, and that it had some ability to coordinate with the tribes on the ground, suggesting that the moon gun, like the tribes, had been ready to go sometime back before.
As recently as last May, they had hoped to cobble together something out of existing nuclear gear and rocket engines at sea, and Christiansted and the other observatories had been working to locate the moon gun to within a kilometer, which they were estimating would be the necessary accuracy since they were only getting one shot.
But nanospawn and biotes had beaten them to the punch; the last, crumbling nuclear carrier had barely made it home to ground on a Georgia beach two months ago, its inventory of rocket and jet fuel already turning to slimy, stinking soap and its computers and communications gear turning to crumbly white powder. Nothing remained of the old Navy and Air Force; probably nothing on Earth now could get as high as 20,000 feet above the ground, let alone to the moon.
Highbotham drummed her fingers. That’s why it doesn’t make any sense for us to bother about them. Not the issue. The Temper government at Athens’s first exploration mission to Europe was going by sailing ship, for the love of god, barely a step up from Provi explorers and scientists who went out from Puget Sound as paying passengers on coffee clippers. Pueblo’s “aerial reconnaissance” was almost entirely mailplane pilots’ handwritten notes and maps.
Heather’s RRC in Pueblo just archived Highbotham’s reports; nothing they can do. Right now we’d have a hard time attacking the moon gun if it was in Vermont.
But no one had told Highbotham’s team to stop, and they needed something to do besides feeding and educating the Academy kids, so for now, they carried on.
But that was what was normal, now. The new normal, they’d have called it when she was a young commander on an old destroyer. The tech of 1850 or 1900 is the new normal.
But normal was the wrong place to look for an answer.
This particular moon gun shot was utterly abnormal.
Since May, the moon gun had fired only when it was in bright sunlight; yet tonight, the moon was waning gibbous, so Fecunditatis was in full darkness, and all the observers had a good fix on the flash. And why fire at all? Till now the moon gun had always targeted large, fixed radio stations, but there were none of those left.
Yet something was wrong. She was sure of it. Was the clue on Earth, or on the moon?
Shit.
The moon was slightly south of bang overhead. High tide here comes about three hours after lunar transit, so the tide’s about half run in. Highbotham’s last few commands before retirement had been in the perpetual overseas wars of the 20-teens, in small surface warships. She had planned dozens of raids, invasions, and landings, both in staff college and for real, and sea raids come in with the tide and go out with it. And that gigantic tribal raid that destroyed the West Texas Research Center used the moon gun as a diversion.
“Raiders,” she said. Her observer team turned and stared at her. “Raiders have probably already landed somewhere on the island.”
Not questioning, not panicking, they moved faster than Highbotham could rattle off reminders. “Henry, Peggy, blinker to the regular watchtowers and Christiansted militia. Signal Cuppa Joe too—Fanchion’s ships travel well-armed and they’ll give us a hand. Richard, Abby—”
“Kids,” Abby said.
“Right. Keep them quiet. Little ones to shelters along with the books—”
“Big ones to battle stations. On our way, Captain.” Richard bolted like a bull with bees on its butt; Abby ran after him, hair and long skirts streaming.
“Gilead—”
“—charts and plots into the safe,” he said, not looking up from his quick folding and stacking.
Henry yanked up and slammed down with the whole force of his scrawny body on the long lever linked to a line of modified tire pumps, making a deafening clatter. Air and methane flowed; Peggy lit the torch and adjusted it to play on the stick of calcite, then closed the door on the steel drum. The limelight blazed to life. Peggy chopped the light on and off with the slatted wooden blind covering the open end. The wooden pieces rattled and thumped despite all the lard lubricating them, adding to the din of Henry’s gasping and pumping and the fierce deep hiss of gas on calcite. Peggy swung the blinker to signal Christiansted, then the watchtower chains east and south of them, and—
“Cuppa Joe is already signaling,” Peggy said. “They must have read our blinker to Christiansted. They’re weighing anchor and moving out for sea room, requesting any info we have on the raiders’ position. Answering with—”
A blinker flashed far down the eastern shore. Henry said, “Chenay Bay reports all quiet, they’ve relayed to Prune Bay and are waiting for—”
The flashing dot went out; a huge orange flame leapt up. Chenay Bay watchtower must have had just time to throw a signaling lantern against the pre-laid warning fire.
Highbotham held her voice low and even. “Peggy, is Murcheson on line now?”
“They just said so.”
