angled, the Waldahud couldn't see Keith. 'I have been analyzing the radio noise we've been detecting near the twenty-one-centimeter band. You won't believe what I've found. Come to my office at once.'
Keith put down his eating utensil, and looked across the table at his wife. 'I'll join you,' he said, and stood up to leave. As they made their way across the room, he realized it was the only thing he'd said to her during the entire meal.
Keith and Rissa got into an elevator. As always, a monitor on the cab's wall showed the current deck number and floor plan: '26,' and a cross shape with long arms. As they rode up, and the deck numbers counted down, the arms of the cross grew shorter and shorter. By the time they reached deck one, the arms had almost completely retracted.
The two humans got out and entered the radio-astronomy listening room.
Hek, a small Waldahud with a hide much redder in color than Jag's, was leaning against a desk.
'Rissa, your presence is welcome' — the standard deference shown females.
A tilt of the head: 'Lansing.' The rude indifference reserved for males, even if they were your boss.
'Hek,' said Keith, nodding in greeting.
The Waldahud looked at Rissa. 'You know the radio noise we've been picking up?' His barking echoed in the tiny room.
Rissa nodded.
'Well, my initial analysis showed no repetition in it.' He swiveled a pair of eyes to look at Keith. 'When a signal is a deliberate beacon, it usually has a repeating pattern over a course of several minutes or hours. There's nothing like that at work here. Indeed, I've found no evidence of any overall pattern. But when I started analyzing the noise more minutely, patterns of one-second duration or less kept cropping up. So far, I've cataloged six thousand and seventeen sequences. Some have only been repeated once or twice, but others have been repeated many times. Over ten thousand times, for a few of them.'
'My God,' said Rissa.
'What?' said Keith.
She turned to him. 'It means that there might be information in the noise — it might be radio communications.'
Hek lifted his upper shoulders. 'Exactly. Each of the patterns could be a separate word. Those that occur most frequently could be common terms, maybe the equivalent of pronouns or prepositions.'
'And where are these transmissions coming from?' asked Keith.
'Somewhere in or just behind the dark-matter field,' said Hek.
'And you're sure they're intelligent signals?' asked Keith, his heart pounding.
Hek's lower shoulders moved this time. 'No, I'm not sure. For one thing, the transmissions are very weak. They wouldn't be discernible from background noise over any great distance. But if I'm right that they're words, then there does appear to be some discernible syntax. No word is ever doubled. Certain words only appear at the beginning or end of transmissions. Some words only appear after certain other words. The former are possibly adjectives and adverbs, and the latter the nouns or verbs they are modifying, or vice versa.' Hek paused. 'Of course, I haven't analyzed all the signals, although I am recording them for future study. It's a constant bombardment, on over two hundred frequencies that are very close to each other.' He paused, letting this sink in. 'I'd say there's a good possibility that there's a fleet of craft hiding inside or just past the dark-matter field.'
Keith was about to speak again when Hek's desk intercom bleeped.
'Keith, Lianne here.'
'Open. Yes?'
'I think you'll want to come to the bridge. A watson has arrived with word that the boomerang has returned from shortcut Rehbollo 376A.'
'On my way. Summon Jag, too, please. Close.' He looked at Hek.
'Good work. See if you can narrow down the source of the signals further. I'll have Thor take Starplex in a circular path around the dark-matter field, scanning for tachyon emissions, radiation, thruster glow, or any other signs of alien ships.'
Keith strode onto the bridge, Rissa right behind him. They moved to their workstations. 'Trigger watson playback,' said Keith.
Lianne pushed a button, and a full-motion video message appeared in a framed-off section of the holographic bubble.
The image was of a Waldahud male with a silvery-gray hide. PHANTOM replaced the sound of the creature's barking with English words for the playback into Keith's ear implant, although, of course, they didn't fit the movements of the Waldahud's mouth.
'Greetings, Starplex.' The status line at the bottom of the screen identified the speaker as Kayd Pelendo em-Hooth of the Rehbollo Center for Astrophysics. 'The boomerang sent to the shortcut designated Rehbollo 376A has returned. I suspect you'll want to stay where you are, investigating the shortcut you're at now, since its appearance on the network is unexplained. However, we thought Jag and others would be interested in seeing the recordings made by the boomerang just before returning home. They are appended to this message. I think you will find them… interesting.'
'Okay, Rhombus,' said Keith. 'Use the data from the boomerang to create a spherical holo display around us. Show us what it saw.'
'A pleasure to serve,' said Rhombus. 'Downloading now; the display will be ready in two minutes, forty seconds.'
Lianne rubbed her hands together. 'It never rains but it pours,' she said, turning around and grinning at Keith. 'Yet another new sector of space opened up for exploration!'
Keith nodded. 'It never ceases to amaze me.' He got up from his chair, and paced a little, waiting for the hologram to be prepared.
'You know,' he said absently, 'my great-great-grandfather kept a diary. Just before he died, he wrote about all the great advancements he'd seen in his lifetime: radio, the automobile, powered flight, spaceflight, lasers, computers, the discovery of DNA, and on and on.' Lianne seemed rapt, although Keith was aware that he might be boring everyone else. To hell with them; rank had its privileges, chief among them the right to ramble on.
'When I read that as a teenager, I figured I'd have nothing to write about for my own descendant when my life came to a close.
But then we invented hyperdrive and AI, and discovered the shortcut network, and extraterrestrial life, and learned to talk to dolphins, and I realized that—'
'Excuse me,' said Rhombus, his lights flashing in the strobing pattern high species used to signal an interruption, 'the hologram is ready.'
'Proceed,' Keith said.
The bridge darkened as the image of Starplex's current surroundings was shut off, shrouding the room in featureless black. Then a new picture built up from left to right, scan line by scan line, washing over the bridge, until it seemed once again to be floating in space — the space of the newest sector to become accessible to the Commonwealth races.
Thor let out a long, low whistle.
Jag clicked his dental plates in disbelief.
Dominating the view, receding slowly, was another fiery green star, perhaps ten million kilometers from the shortcut point.
'I thought you said our green star was a freak,' said Keith to Jag.
'That's the least of our worries,' said Thor. He swung his feet off his console and turned to face Keith. 'Our boomerang didn't activate that shortcut until it dived into it.'
Keith looked at him blankly.
'And these pictures were taken before it did that.'
Jag rose to his feet. 'Kadargt. That means—'
'It means,' said Keith, suddenly getting it, too, 'that stars can emerge from dormant shortcuts. Christ, they could be popping out of all four billion portals throughout the Milky Way!'
