After a quick appraisal, Smith had ordered a descent into a thousand-kilometre orbit. His fleet moved in, the combat-capable starships dumping small satellites in their wake to form an extensive high-orbit gravitonic-distortion-detector network. If any starship emerged within five hundred thousand kilometres of the planet, the satellites would spot it.

The blackhawks released a quintet of military-grade communication satellites as they raced towards the planet. Ion engines pushed the comsats into geostationary orbit, positioning them to give complete coverage of the planet, with overlapping reception footprints covering Amarisk in its entirety.

Twenty thousand kilometres out from Lalonde, the blackhawks split into two groups and swept into a seven-hundred-kilometre orbit at differing inclinations. Each of them released a batch of fifteen observation satellites, football-sized globes that decelerated further, lowering themselves into a two-hundred-kilometre orbit; their parallel tracks provided a detailed coverage sweep over a thousand kilometres wide. The blackhawks themselves, with their powerful sensor blisters augmented by electronic scanner pods, were integrated into the effort to reconnoitre Durringham and the Juliffe tributary basin. The intention was to compile a comprehensive survey with a resolution below ten centimetres for the mercenary scouts to use.

“It’s virtually impossible,” Idzerda, the captain of the blackhawk Cyanea , told Terrance Smith after the first pass. “That red cloud is completely opaque, except for the edges where it thins out, and even there the images we’re receiving of the land below are heavily distorted. I’m not even sure cloud is the word for it. It doesn’t move like cloud should. It’s almost as if a film of electrophorescent cells has been solidified into the air. Spectrographic analysis is useless with that light it emits. One thing we have noticed; we ran a comparison with the old cartography memory from the sheriff’s observation satellite which you supplied. The cloud is brightest over towns and villages. Durringham shines like there’s a star buried under there. There is no way of telling what is going on below it. The only villages we can even see are the ones furthest up the tributaries where the glow peters out. And they are wrong.”

“Wrong?” Terrance Smith asked.

“Yes. They’re the most recently settled, the most primitive ones, right?”

“Yes.”

“We’ve seen stone houses, gardens, domelike structures, metalled roads, heck, even windmills. None of it was there on the old images you gave us, and they were only recorded a month ago.”

“That can’t possibly be correct,” Terrance said.

“I know that. So either the whole lot are holograms, or it’s an illusion loaded directly into the observation satellite processors by this electronic warfare gimmick you warned us about. Although we can’t see how it disrupts the blackhawks’ optical sensors as well. The people who put up that cloud have got some startlingly potent projection techniques. But why bother? That’s what we don’t understand. What’s the point of these illusions?”

“What about power emission centres?” Terrance Smith asked. “It must take a lot of energy to generate a covering layer like that red cloud.”

“We haven’t found any. Even with their electronic jamming we should be able to spot the flux patterns from a medium-sized fusion generator. But we haven’t.”

“Can you locate the jamming source?”

“No, sorry, it’s very diffuse. But it’s definitely ground based. It only affects us and the satellites when we’re over Amarisk.”

“Is the red cloud radioactive?”

“No. We’re fairly sure of that. No alpha, beta, or gamma emission.”

“What about biological contamination?”

“No data. We haven’t attempted to sample it.”

“Make that your priority,” Terrance said. “I have to know if it’s safe to send the combat scout teams down.”

On its following pass, the Cyanea released two atmospheric probes. The vehicles were modified versions of the marque used by planet-survey missions, three-metre delta-wing robots with the central cylindrical fuselage crammed full of biological sampling and analysis equipment.

Both of them pitched up to present their heatshield bellies to the atmosphere, curving down towards the surface as they aerobraked. Once they had fallen below subsonic velocity, airscoop intake ramps hinged back near the nose, and their compressor engines whirred into silent life. A preprogrammed flight plan sent them swooping over the first fringes of the red cloud, fifteen kilometres to the south-east of Durringham. Encrypted data pulsed up to the newly established bracelet of communication satellites.

The air was remarkably clear, with humidity thirty per cent down on Lalonde’s average. Terrance Smith accessed the raw image from a camera in the nose of one probe. It looked as though it was flying over the surface of a red dwarf star. A red dwarf with an azure atmosphere. The cloud, or haze—whatever—was completely uniform, as though, finally, an electromagnetic wavefront had come to rest and achieved mass, then someone had polished it into a ruby surface. There was nothing to focus on, no perspective, no constituent particles or spores; its intensity was mechanically constant. An optically impenetrable layer floating two kilometres above the ground. Thickness unknown. Temperature unknown. Radiating entirely in the bottom end of the red spectrum.

“No real clouds anywhere above it,” Joshua murmured. Like most of the fleet’s crews he had accessed the datavise from the atmospheric probes. Something had bothered him about that lack; ironically, more than the buoyant red blanket itself. “Amarisk always had clouds.”

Sarha quickly ran a review of the images the fleet had recorded on their approach, watching the cloud formations. “Oh my Lord, they split,” she said disbelievingly. “About a hundred kilometres offshore the clouds split like they’ve hit something.” She ran the time-lapse record for them, letting the tumbling clouds sweep through their neural nanonics’ visualization. Great billowing bands of cumulus and stratocumulus charged across the ocean towards Amarisk’s western shoreline, only to branch and diverge, raging away to the north and south of the Juliffe’s mouth.

“Jesus. What would it take to do that? Not even Kulu tries to manipulate its climate.” Joshua switched back to a real-time view from Lady Mac ’s sensor clusters. A cyclone was being visibly sawed into two unequal sections as it pirouetted against the invisible boundary. He ordered the flight computer to open a channel to the Gemal .

“Yes, we’ve seen it,” Terrance Smith said. “It has to be tied in with the red cloud cover. Obviously the invaders have a highly sophisticated method of energy manipulation.”

“No shit? The point is, what are you going to do about it?”

“Destroy the focal mechanism.”

“Jesus, you can’t mean that. This fleet can’t possibly go into orbit now. With that kind of power available they’ll be able to smash us as soon as we’re within range. Hell, they can probably pull us down from orbit. You’ll have to abort the mission.”

“It’s ground based, Calvert, we’re sure of that. It can’t be anywhere else. The blackhawks can sense the mass of anything larger than a tennis ball in orbit, you can’t disguise mass from their distortion fields. All we have to do is send in the combat scout teams to locate the invader’s bases. That’s what we planned on doing all along. You knew that when you signed on. Once we find the enemy, the starships can bombard them from orbit. That’s what you’re here for, Calvert. Nobody promised you an easy ride. Now hold formation.”

“Oh, Jesus.” He looked round the bridge to make sure everyone shared his dismay. They did. “What do you want to do? At five gees I can get us to a suitable jump coordinate in twelve minutes—mark.”
