MURDER BY NUMBERS

Forty light years from Earth, the yacht Gloriana congealed out of the cold emptiness between stars, emitting an electric blue flare of Cerenkov radiation. If it drifted at the residual velocity carried over from its last reference frame shift, it would take nearly two hundred years to cover the distance separating it from the star system it was heading for, but drifting wasn’t the name of the game. After only a few minutes the ship’s inertial transfer unit came online. Lidar probed the space ahead for obstacles as the yacht came under acceleration.

The Gloriana had started life as a billionaire’s toy, but these days almost half the passenger volume was filled by the extensive diplomatic function spaces of a mobile embassy. The ship — and its three sisters — existed because it was cheaper for the UN to swallow the extra costs of running a starship than maintaining consulates on the couple of hundred planets that received visitors from Earth more than once in a decade but less than a thousand times a year. Now running between jump zones at full acceleration, Gloriana had been under way for a week; over the course of which time Rachel Mansour had become increasingly annoyed and worried by George Cho’s refusal to disclose the purpose or destination of the mission.

Finally, however, it looked as if she was about to get some answers.

The conference room was walled in a false woodgrain veneer that hardly sufficed to cover the smart skin guts of the ship. Tricked out in natural surfaces, the whole thing was as artificial as a cyborg smile. Maybe the big boardroom table (carved in the ornate intricacies of the neo-retrogothic fad of a century earlier) was made of wood, but Rachel wasn’t betting on it. She glanced round the occupied chairs as she sat down, recognizing Prifkin, Jane Hill, Chi Tranh, and Gail Jordan. George’s little munchkins are out in force, she noted ironically. She’d worked with most of them in the past; the lack of new faces told its own story.

“I take it nothing’s running to schedule, is it?”

“The best-laid plans of mice and men,” Cho commented apologetically. “You can lock the door now,” he told Pritkin. “I’ve got some papers for you, dumb hard copy only, and they do not leave this room.” He reached under the desk and retrieved six fat files, their covers banded with red and yellow stripes, then tapped a virtual button on his pad. There was a faint hissing sound from the air conditioning. “We’re now firewalled from the rest of the ship. No bandwidth, bottled air, and the ship itself isn’t within hailing distance of anything else … you can’t be too careful with this stuff.”

Rachel’s skin crawled. Last time she’d seen George put on the full-dress, loose-lips-sink-ships song and dance it had been the run in to the mess on Rochard’s World. Which had involved dirty-tricks black ops that could have backfired to the extent of starting an interstellar war. “How does this rate with the last, uh, mission?” she asked.

“Messier. All turn to page 114.” There was a rustle of dumb paper as everybody opened their files simultaneously. Someone whistled tunelessly, and Rachel glanced up in time to see Gail looking startled as she studied the page. Rachel began to read just in time for George to derail her concentration by talking. “Moscow. Named after the imperial capital of Idaho rather than the place in Europe, except Idaho didn’t have an empire back when the Eschaton grabbed a million confused Midwestemers from the first republic and stuffed them through a wormhole leading to the planetary surface.”

The words on the page swam before Rachel’s eyes: Bill of indictment in re: signatories of the Geneva Conventions on Causality Violation versus Persons Unknown responsible for the murder of—

“Moscow was, bluntly, another boring McWorld. And a bit backward, even by those standards. But it had a single — and fairly enlightened — federal government, a single language, and no history of genocide, nuclear war, cannibalism, slavery, or anything else very unpleasant to explain it. It wasn’t Utopia, but neither was it hell. In fact, I’d have said the Muscovites were rather nice. Easygoing, friendly, laid-back, a little sleepy. Unlike whoever murdered them.”

Rachel leaned back in her chair and watched George. Cho was a diplomat, and a polished and experienced gambler who liked nothing better than a game of three-stud poker — so the experience of seeing him actually looking angry and upset about something was a novelty in its own right. The wall behind him showed supporting evidence. Rippling fields of grain as far as the eyes could see, a city rising — if that was the word for an urban sprawl where only city hall was more than three stories high — from the feet of blue-tinted mountains, white-painted houses, huge automated factory complexes, wide empty roads stretching forever under a sky the color of bluebells.

“Not everyone on Moscow was totally laid-back,” George continued, after taking a sip from his water glass. “They had a small military, mostly equipped for disaster relief work — and a deterrent. Antimatter-fueled, ramscoop-assisted bombers, hanging out in the Oort cloud, about twelve light hours out.”

The wall dissolved into icy interstellar darkness and a close-up of a starship — not an elegant FTL yacht like this one, with the spherical bump of its drive kernel squatting beneath a tower of accommodation and cargo decks, but the evil angular lines of a planet-buster. Most of the slower-than-light bomber consisted of fuel containment vessels, and the huge inverted funnel of the ram field generator. Scooping up interstellar hydrogen for reaction mass, using antimatter to energize it, the warship could boost itself to more than 80 percent of lightspeed in a matter of weeks. Steering toward a target, it would then drift until it was time for terminal approach. Then, instead of decelerating, the crew and the ramscoop would separate and make their own way — leaving the remains of the ship to slam into the target planet.

“This is a reconstruction of a Muscovite Vindicator-class second-strike STL bomber. Our best intelligence gives it a maximum tau factor of point two and a dry rest mass of three kilotons — extremely high for the product of a relatively backward world — with an aggregate kinetic yield of 120 million megatons. It’s probably designed to prefragment prior to impact, and coming in at 80 percent of lightspeed with several hundred penetration aids and a wake shield against ablator clouds, it would be able to saturate any reasonable planetary ballistic defense system. It would deliver about 20 percent more energy than the Chicxulub impactor that hit Earth 65 million years ago, enough to devastate a continent and trigger a dinosaur winter. In other words, it’s a pretty typical second-strike slower-than-light deterrent for a planet that didn’t have any enemies or major foreign policy engagements; an insurance policy against invaders.

“Moscow had four of these monsters, and we know for sure that the early warning system alerted them before the stellar shock front reached their fire-bases; we know at least three of them came under acceleration. What happened to the fourth ship is unclear at this time. They probably took some serious damage from the nova, but we have to assume that those four ships are engaged on a strike mission.”

George sat down again and refilled his water glass. Rachel shivered slightly. They launched? But where to? The idea was disquieting, even revolting: “Has anyone ever actually launched an STL deterrent before, that you know of? I don’t think I’ve ever heard of one being used…”

“May I?” It was Chi Tranh, lean-featured and quiet, the expert on weapons of mass destruction and, sometimes, her back-office researcher. Not a field agent, but George had evidently included him in the operation from the start, judging by the way he nodded along. “The answer is no,” said Tranh. “We have never seen one of these weapons systems used in anger. Nobody can start a war using STL ships — it would give years for a pre-emptive retaliatory strike. The idea is simply to have a deterrent — a club up your sleeve that makes the cost of invading and occupying your world too expensive for an aggressor to bear. This is a first, at least within our light cone.” He sat back and nodded at George.
