In the past, the trade with the Tropics had been an almost unrecognized silent barter, where bid and response were spread across years of occasional shipwrecks. The "Tropical Embassy" had begun as a charity for shipwrecked singletons, a joke of an embassy. Now the joke had a life of its own and-maybe-some influence in the South.

Ravna crossed her arms and gave the ambassador a look. It was amazing the effect the soundless stare of a two-legs could have on some packs.

Whatever the reason, the ambassador gave a shrug. "Oh, very well. We, of course, have nothing to hide."

Ravna gave an inward sigh of relief. Now to find who really did the thieving. She turned to the crowd behind her. A couple of dozen humans stood nearby, looming tall over the packs. And one at the back- "Hei, Nevil! How long have you been here?"

Johanna's fiance trotted forward, a couple of his friends close behind. "Just got here. I was at the top of the quarry when I saw everybody go berserk." Nevil stopped beside her. He was still breathing heavily. "I heard the last part though. You want these fellows searched?"

Scrupilo was nodding. "Yes. You humans can get in close without upsetting our delicate guests." He jabbed sarcastically in the direction of the Tropicals, but his gesture lacked spirit. "I was so sure it was them," he grumbled to himself.

Nevil squatted down so he could speak more privately. No human could direct sotto voce mutterings as well as a pack. Ravna leaned closer. "Godsgift did give in a bit easily," said Nevil. "Are you sure you have all his entourage here?"

Scrupilo's eyes widened. He poked a head up and gave the Tropicals a long look. "They're so hard to count." He did a double take. "God's Choir, Nevil, do you think they split off an extra pack?"

Ravna looked at the visitors. The Tropicals always seemed a bit strange, with their patchy fur, body paint, and mismatched clothing. Now that they weren't jammed against the airship, they had separated into something like packs, mostly foursomes. If they had come in with extra members, then split to make an additional pack.... It was the sort of playing with souls that would have left Domain packs dazed and disoriented.

Scrupilo looked back and forth at the Tropicals. "I don't know how many came in, but ... look at that body paint. Don't you think there are gaps within those two fellows at the end? These are Tropicals. There's no end to their perversions."

Godsgift might be hearing every word. In any case, it was becoming restive: "I say, Your Highness. We've agreed to be searched. Be about the indignity, if you please!"

"Just a moment more, Mr. Ambassador." Ravna dropped back into her head-to-heads with Nevil and Scrupilo. "I have no idea, Scrupilo. Those paint jobs mean less to me than anyone." I wish Pilgrim were here. Pilgrim would know just what the Tropicals could do with themselves.

Nevil turned, waved one of his friends forward. Then he continued, whispering. "Actually, Bili saw something weird when we were up on top of the quarry."

Bili Yngva dropped to his knees beside them and nodded. "Yeah. There was a fivesome skulking around the quarry hoists. Its panniers were stuffed. When I tried to get a closer look, the critters took off for the boat landings. And the strangest thing-I think there were blue smudges on its pelt, like these fellows' body paint, but rubbed off."

Scrupilo let out a hoot of triumph. "I knew it!" Then he dithered. In a second more, orders would be flying in all directions.

Nevil stood up, gave Ravna a look. "Your Highness?"

Yes, Ravna abruptly realized, it's time to act the co-Queen. She put a restraining hand on one of Scrupilo's heads. "Please bear with me, Mr. Science Advisor." Then she stood and turned to the crowd, which itself was milling uncertainly about. "People! People!" Well, that worked in the classroom. And goodness, it got everyone's attention here, too! "We're going ahead with the property search the Ambassador just agreed to. Scrupilo will advise, but I want humans to do the close-in." Who? She was suddenly even more grateful that Nevil had shown up. He was on good terms with all the kids, and was a born leader. "Nevil Storherte will supervise."

She said, in an aside to Nevil: "Is Johanna close by?"

"Sorry, she's on the mainland this afternoon."

"Okay, check out our visitors."

Nevil nodded, and began to gather a proper crew. Ravna glanced at Godsgift. "We'll have you out of here very soon, Mr. Ambassador."

The Tropical leader smiled broadly. "Excellent." Quite evidently, it had no worries about its guilt being proven here.

Scrupilo was dancing with frustration. His gobbling chords broke into a hissed Samnorsk whisper. "This is all useless! I should phone the boat moorage, put out an island-wide alarm, and contact Oobii."

They also needed some aerial surveillance.... She looked up at the airboat that had been the backdrop for this confrontation. "Is the Eyes Above flyable?" She pointed at the aircraft. "And does it have a radio on board?"

"What? No radio, but the motor is charged ... hmm, grmm! Yes!" He started shouting to his ground crews, chords and Samnorsk all mixed together, in various loudnesses and different directions. What she could understand was: "Phone Woodcarver!", "Nevil, move your investigation away from the Eyes Above! I have use for it." And a whisper for her ears: "The craft is fully prepped. I wonder if Mr. Crapheads knew that." He ran to the wicker basket as two of his helpers approached from the other side. They were fiddling with a row of gas valves, arguing with Scrupilo about details.

Nevil's people and the Tropicals had moved twenty meters off. The suspects were grudgingly removing their panniers and jackets. Huh, the intricate body painting covered much of their bare skin. Some of the Tropicals were watching the airboat curiously, but they didn't seem the least disconcerted by Scrupilo's activity.

One of Scrup's assistants came rushing out with the lab's loose radio. The nearest of Scrupilo grabbed the box and passed it to himself, up the gangplank. Then he hesitated, looking around as though he had forgotten something critical. "Oh, if only Johanna were here. This will go better with a combo crew." That is, a pack and a human. "Nevil!" he shouted.

Ravna put a foot on the gangplank. "That's okay, I can help you as well was anybody here." That was probably true; she'd been up with Scrupilo a number of times. Besides, she didn't want to stay here and second-guess Nevil.

Nevil Storherte had started back in their direction. For a second, Ravna thought he was going to object. The boy-no, the man; he was only eight years younger than she-was always going on about her indispensable role in high planning. This time, he seem to realize that he already had a job and that seconds counted. He hesitated, then gave her a little wave. "Okay. Good hunting."

She waved back, then shooed the rest of Scrupilo up the ramp, into the airboat's narrow basket.

For once, Scrupilo was not arguing. He scrambled aboard, all the while shouting to his ground crew. The basket did its usual disconcerting wobble as Ravna climbed across into the chair at the stern. She wasn't quite tied down when the ground crew cut the tethers and the balloon drew them firmly skywards.

This was almost like agrav-but steadier then Pilgrim's flier. The ground simply fell away. Looking over the edge of the basket, she could see all the Tropicals' gear laid out. No way that an entire set of radio cloaks could be hidden in that.

Scrupilo powered up the boat's propeller and turned the rudder. They were over the dark ponds that filled the old mining pits and covered the lab's tanks of stabilized hydrogen. The placid waters reflected the towering walls of the quarry. If she leaned further out, she'd be able to see the reflection of the airboat.

... But not just now. Ravna tied onto a safety harness and began crawling around the aft end of the basket. There were a number of equipment cabinets, mostly waterproofed wicker, with latches that could be released by hands or paws or jaws. She opened one after another, glancing in each: a heliograph (not enough radios to go around), maps, two telescopes. It suddenly occurred to her that there was something to check before anything else. She set the spyglasses down and turned to the stern cover.

"Highness," Scrupilo shouted to her. She looked out, saw that they had cleared the top of the quarry. "Please handle the driving. I'm best with the telescopes." Then he noticed that Ravna was trying to pull up the stern ballast cover. "Highness? The telescopes, please ... What are you doing?"

"It just occurred to me-what if they stuffed the cloaks in the ballast tanks?"

"Uck." The pack thought a second, no doubt imagining how this chase could wreck what they were trying to recover. It was a long shot, but-"I'll check the bow and mid tanks." A pair at a time, Scrupilo's members released the various controls they had jaws on and poked around in the water tanks that were set along the length of the hull. The main rudder slid free and the propeller slowed till you could see its three blades. The Eyes Above slowly turned in the nearly still afternoon air, now pointing toward the outer islands, now at the north channel, now at Starship Hill. They were high enough that she could see the dome of the New Castle.

"There's nothing in these tanks but water," he said returning to his controls.

"Same back here."

"Very well then. Time is wasting." He angled both horizontal and vertical rudders and spun up the screw. Eyes Above's stern gently bobbed upwards, and the airboat angled down, turning toward the island's North End boat landings. "Can you circle us around the North End while I take a look?"

"Yes." Flying was easy in air this placid. The backseat controls included two jaw levers by her chair and another pair set far enough forward that she could use them as foot pedals. Together they provided control of the rudders and propeller. It wasn't as simple as a point-and-move interface, but Ravna had practiced.

Scrupilo hauled the two telescopes forward. The eyepieces were curved masks that could be rotated to fit either side of a member's head. Midway down each barrel was a clasp suitable for the usual shoulder strap on Tinish jackets. In a matter of seconds, he had the scopes mounted on two of himself, and two of his other members were looking around for things to spy on. "Okay. Take us a little north.... Hah. Except for my construction barge, the moorage is almost deserted."

The North End moorage had been mostly taken over by Scrupilo's serious aircraft project, the creation of a rigid airship. The superstructure of the Eyes Above 2 was already evident in the spars and ribs rising from the construction barge. When completed, in another half year or so, the EA2 would be more than two hundred meters long, capable of transporting a dozen packs across the continent nonstop.

Most of Scrupilo was maneuvering the two telescopes like binoculars, sweeping across the piers and boat shelters. The rest of him lay together in the bottom of the basket, as if asleep. More likely, they were busy with the others, bringing all that two of them were seeing into a single, analyzed vision.

Scrupilo was humming to himself; at least the chords meant nothing to Ravna. "Ha! I see the pitter-patter of wet paws along the quay. See the gap in the moorage? Some pack was down here recently, departing in one of the single-hulled day fishers. So we know what to look for!" The two telescope bearers stood down. The others spread out to the ballast dumps. "Let's get upstairs quickly, Your Highness!" He dumped some water. One way or another, they were going up.

Ravna angled them northwest, across the outer straits. The channel islands were numerous, forested, and largely uninhabited. If the thief made it there he could probably get away.

Scrupilo glanced at the gear-driven clock he kept on White Head's jacket. "Take us to Ridgeline, that's the only place the thief could have reached in this direction." He was on his telescopes again, scanning the open water, all the way to where sea mist hung round the furthest islands. "Hmm, a couple of twinhulls, nothing like our fellow."

They drove along for a few seconds, the propeller pushing them along at about five meters per second. The wicker basket was a cold, shadowed place, but at least the air stream was diverted by the basket's bow cowling.

Ravna locked down the rudders and rummaged around for the radio that Scrupilo had brought aboard. These radios were one of the stranger of Oobii's reinventions. Of course, the device had no onboard processors; it was totally analog, indiscriminately spewing across the entire radio spectrum. No matter. The starship monitored all aspects of the space around it.

"Ship. Can you see where I am?" Ravna asked into the microphone.

"Ravna. Yes," acknowledged a pleasant male voice, something like Pham's voice perhaps. But there wasn't a bit of mind behind this voice. Oobii's automation was simply the best computation that could run in the Slow Zone. By now she was almost used to the interface, and it was the best she could do when she wasn't wearing the data tiara.

She described the problem situation in terms the starship could work with. "And watch for radio lights near my location."

"Watching," Oobii replied.

"What transmissions do you see, out to, ah, four thousand meters?"

"I see a number of-"

"Ignore the North End lab."

"-I see one, your current transmission."

"Do you see any radio light from Ridgeline Island?"

"The radio frequency energy from Ridgeline Island appears to be normal scattering."

"Okay," said Ravna. "Ongoing: report on artificial radio light seen within, um"-Here she really needed a better interface. She settled for something short and crude.-"everything within ten thousand meters of the north end of Hidden Island."

"Done and ongoing. Do you want the reports streamed now?"

Ravna thought a second. "No. Report anomalies and forwarded transmissions." There were several radios that might legitimately be in use at this end of the Domain. They were part of the clunky forwarding operation that Oobii managed.

"Very good," replied Oobii. "I see nothing unusual at this time."

"You know, Your Highness, praps you should let me manage the radio interface." Scrup was almost as clever with voice comms as Woodcarver.

"No, keep your attention on the ground."

Scrupilo grumped around the basket. Their path had taken them in a low sweep of Ridgeline's shore, giving his telescopes a view beneath the tall evergreens. "There's nothing down there, no marks in the sand, and this is about the only place they could have reached land by now. The thief is either holed up on Hidden Island or he's on the inland channel, heading for the mainland. And now we'll never catch up! We are useless."

Scrupilo was like that, getting all frustrated and then giving up for a while. But Ravna was just getting interested in the problem. Given both the Eyes Above and the Oobii, there were some possibilities. She chatted with Oobii. It reported a mainland-trending windstream about five hundred meters up and a few hundred meters south. They dumped a little ballast. She brought the rudders around and drove the propeller as fast as its little electric motor could go. The airboat angled upwards, Ravna steering according to directions from the starship. It was fun as long as she didn't dwell on the fact that she was reduced to being a mere servomechanism for her starship's very dumb automation.

They climbed their invisible staircase, turning through 180 degrees as they went. Scrupilo looked out in all directions, then concentrated his attention on the Inner Channel, between the mainland and Hidden Island. Every few seconds he'd comment on the new areas he could see. "Still no sign of ... But wow, the ground speed! Milady, your maneuver is worthy of Johanna herself!" The starship reported that the Eyes Above was driving along at almost twenty meters per second. "And I can see the whole of the mainland shore. Mark my words, we'll catch this thief!"

They drilled along, airspeed no greater than before, but the North End lab passed below them and they were already cruising southward along the Inner Channel. Oobii reported no new radio emissions. Of course, it had been a long shot that the thief would try to wear the radio cloaks. To the Tines, the devices were almost religious icons. Wear them, and you'd most likely fry your mind-but if that didn't happen then you were transformed into a godlike pack who could stride the world with kilometers between one's pack members! Somebody like Godsgift might be arrogant enough to wear the cloaks in the middle of trying to steal them, but that was probably not true of his minions.

She looked out at the cliffs of the mainland, the shoulders that Starship Hill rested upon. If somehow the thief got ashore, it would be hiding in the evergreens that grew in the steepness. Oobii said there would be a summer rain shower in another few hours. Under cover of that, the thief might make it to whatever rendezvous the Tropicals had planned. She looked at the froth of dying spring leaves that floated in the evergreens' crowns. In most places, the ground was hidden. Oobii had no line of sight on these cliffs. Even so ... she gave the starship another call.

Scrupilo's attention was on his telescopes; apparently he didn't notice what Ravna was saying to the Starship. He pointed a snout downwards. "There are Woodcarver's troops coming down to the mainland shore! We should tell them that I've covered the shore north of us. Forward a call to them, Your Highness."

Then her science advisor noticed that she wasn't making the call. "Your Highness!"

"Just a moment, Scrupilo. We may be able to detect the cloaks, even if they're not turned on."

"But we need to make that call to Woodcarver!" Even his telescope members were looking around at her. Then he gave a start and began to sniff at his fur. "Wow! Did you feel that, Your Highness? Like a tiny electric shock, but through all my members, all at once."

Ravna hadn't felt a thing; maybe that was because she didn't have six fur-covered bodies. However, she had an explanation. "Oobii just hit us with a very bright pulse. Even if the cloaks are turned off and around a corner, they might give back an echo."

"Ah!" One good thing about Scrupilo, he really admired clever surprises. "Well, in that case, I'm pleased to be your personal radio pulse sensor."

Ravna grinned back and put through a call to her starship.

Oobii replied, "Except for known radios, no device echoes detected."

Scrupilo stuck out his snouts from both sides of the basket and took a naked eye look at the passing scene. "I say we radio pulse every so often. No way this Tropical would guess your clever trick, Highness. Sooner or later he'll move where Oobii can detect him."

Ravna set up a surveillance plan with Oobii, got some more winds-aloft advice, and also forwarded Scrupilo's observations through Oobii to Woodcarver. They continued southwards, climbing another hundred meters. They were almost even with the long row of telephone poles that marched off to the south along the Queen's Road.

The Eyes Above wasn't making good time anymore, but it was well ahead of Woodcarver's search parties. Just a few hundred meters to her left, paralleling the telephone poles, were the "town houses" of older Children and wealthy packs. They might be her most visible achievement of the last ten years. Ravna didn't know whether to laugh or cry about that. The half-timbered houses were large, each big enough for a married couple, a young child or children on the way, and one or two pack friends. Oobii was able to keep the buildings warm by shining a very low-power beam gun on the hot water towers that stood next to each house. So the town houses were comfortably warm all year round, with hot and cold running water and indoor plumbing. A large part of Oobii's tech rent had gone into paying for the Children's town houses. The second-generation kids thought they were heavenly. Their parents regarded the houses as a small step up from purgatory.

"Ha. I felt another pulse," said Scrupilo. Ravna called the ship. Still no joy.

"We're almost to Cliffside harbor, Scrupilo. I think that's beyond where the thief could have come." In any case, the straits between Hidden Island and the mainland was far busier than the polluted water at North End. There seemed little hope of spotting a suspicious boat here.

"... Yes. I suppose we should turn around and"-Scrupilo had raised his telescopes, pointing them at the highlands ahead.-"but not just yet! The Tropicals may have outsmarted themselves. Something strange is going on near their madhouse. Can you fly there, quietly?"

The embassy compound was just south of the town houses, a fenced-in collection of ramshackle sheds perched on the edge of the Margrum Valley. "I'll check." She gave Oobii a quick call, then turned back to Scrupilo. "In that direction, we have a southbound breeze all the way to the ground." She ran the propeller for another thirty seconds, long enough to put them on a path that would take them past the compound. They were just a few dozen meters above the heather now. She cut the motor, and they coasting along with the breeze, surrounded by eerie silence. "How's that?"

None of Scrupilo looked up from his intent surveillance. "Excellent. The bastards are up to something. They're in a crowd off to the northwest of the compound."

"What, they're playing with their snow sleighs again?" There'd been heavy snowfall last winter, and the Tropicals had become enamored of large sleighs. Typical of the mob's long-term planning, they had begged and worked to buy a number of sleighs-getting possession just in time for the spring mud.

"No!" said Scrupilo. "These fellows are by the fence, near the telephone trunk line. I wonder how close we can get before they see us."

Ravna glanced behind her. The northering sun was peeking under the curve of the balloon. "We're coming at them from out of the sun." Ahead, she couldn't actually see their shadow on the ground, but there was a bright spot, a glory shine, in the heather beyond the compound, marking just where their shadow must be. The roundish light had almost reached the edge of the valley. She vented a little hydrogen. As the Eyes Above sank, the bright spot moved into the compound.

"Brilliant, Milady! Can you keep us in the sun all the way down?"

"I think so." When the spot of backscatter brightness drifted beyond the compound, Ravna vented a little more hydrogen. Goodness, this was like having a guide program! She felt a small thrill at finding something so convenient built into the raw nature of the world.

They were about 500 meters from the compound, and losing attitude. Ravna had to push up from her seat to see over the basket's bow. The Eyes Above's shadow was clearly visible now, surrounded by just a halo of backshine. She vented a bit more gas, brought the shadow to just beyond the Tropicals.

There were a bunch of them down there, standing at the edge of the Queen's Road, right where it passed closest to the embassy. This crowd plus the ones at the lab would add up to most of the embassy's total population, though the count was always vague. A number of Tropicals returned south when their wrecks finally slid back to sea. Others had probably been involved in Fragmentarium breakouts over the years.

Ravna could see their ragged jackets and leggings, the body paint on their exposed heads and tympana. There were probably twenty packs' worth, all tangled together. Yup, an orgy in the making.

Now less than two hundred meters away, none of them looked up to see the Eyes Above. Ravna vented a little more hydrogen, keeping their shadow just out of the packs' eyes.

Scrupilo had no need for his telescopes now. Five of him had heads stuck over the rim of the basket, staring down. He wriggled his White Head member back to Ravna. "Sst," whispered White Head. "I can hear them!"

A few seconds passed-and now Ravna could hear them too. The sounds were clear in the wider silence, growing louder as the Eyes Above swept closer, the gobble and hiss of Tinish excitement. The chords were otherwise nonsense to her, but then she could understand very little of the local language, even when the packs were trying their best to be clear.

Scrupilo was not so limited. His White Head reached its nose close to Ravna's face, where its fore-tympanum could whisper even more quietly. "You hear what they're saying? The get of bitches already know about the theft! That's solid proof they're behind it. No way any of their party could be back from the lab this fast!"

Now the Eyes Above was coasting over them. There was no more point in careful navigation. Ravna left her pilot's chair and leaned over the edge of the basket. They would pass dead even with the compound's twisted tower. Directly below, not more than forty meters away, was the mob of Tropicals. These guys did look excited. Then there was a gap in the crowd and she saw the telephone resting on the ground. A thin wire hung down from the nearest telephone pole.

"Oh," said Scrupilo. Well, that explained their excitement, and why they were standing here by the road. Memo: never give half a solution to these critters.
