horses. Now the only way they’d be detected was if an Onid walked directly into them, a chance she was willing to take. She opened one of her saddlebags and took out a slim case with eight eyebirds in it. The little gadgets were disc-shaped, five centimetres in diameter, comprising a slim outer ring crammed with sensor systems, and a central contra-rotating fan. Their motors spun up silently, and they rose out of the case to hover in front of her while her e-butler loaded in a search pattern. As soon as the procedure was complete, they swarmed off into the valley, rising up to a level fifteen-metres altitude.
Images slid up into Paula’s virtual vision. The eyebirds were crammed with an astonishing number of sensors. If there was any kind of abnormality she was sure they could find it for her. It would be a tough search, she admitted after the first five minutes. The valley seemed a pleasantly bucolic place. None of the eyebirds could detect a large thermal source that might indicate a predator of some kind. It was a theory quite high on her probables list, that humans had lost some kind of animal, possibly one of the endangered terrestrial species. She knew that cheetahs and panthers and lions and several other types were bred in secret colonies on some worlds. You paid a small fortune for the privilege of hunting them, but there were always people with that kind of money. And a world like Menard would be the perfect place to set up such an enterprise.
‘I’ve got the burial ground,’ Dino said. ‘Eyebird three, look. But what’s happened to it?’
Paula, who was accessing the feeds from eyebirds eight and five, switched her attention over to three. One of the long stretches of meadowland at the base of a tall rock cliff was the heart of the herd, with the graves showing as small mounds of earth. It needed to be a big area, there were a
‘Are you sure there are no native predators around here?’ Paula asked.
‘We never saw any. There’s a beast in the northern part of this continent, a Gruganat, which is close to a terrestrial lion, but a lot faster. They feed on Onids and other animals. But none have been spotted here.’
‘Could this be the first one? Humans are settling in the north, too; we could have driven them out of their traditional hunting grounds.’
Dino pulled a sour expression. ‘Gruganats prefer fresh meat. And they wouldn’t have any problem killing it here.’
Paula moved eyebird two to cover the burial ground in more detail, directing it down to hover over one of the opened mounds. It wasn’t a particularly deep excavation, the decomposing corpse was just visible at the bottom of the shallow oval hole.
‘It wasn’t a carnivore doing that, then,’ Dino said. ‘The body hasn’t been touched.’
‘Agreed,’ Paula said. ‘And look at the edges of the hole. They’re clean, straight. That was a spade. This is what those riders have been doing.’
‘The totems,’ Dino exclaimed in a shocked tone. ‘They’ve taken the totems. Each Onid is buried with the tribe’s totem. No wonder they’re so angry.’
‘Why? What would anybody want with the totems? Your report said they were just stones.’
‘They are. Pebbles, sticks, even a flower once; each herd has a different one. All they do is reinforce the herd identity, that’s what we thought.’
‘What does this herd use?’ Paula asked.
‘I’ve no idea. Each herd has something that’s abundant in their territory.’
Paula moved eyebird two over to an intact grave. Its sensors gave the mound a fast sweep. ‘There’s some kind of metal in there.’ She read off the results table that slithered across her virtual vision. ‘Definitely metallic, a small lump.’
‘Metal?’ Dino asked. ‘Are you sure?’
She sent the eyebird over to the next grave. Sure enough, it contained a lump of metal, the signature was almost identical. ‘Metal detecting is about the oldest science there is. I can’t determine the composition, unfortunately. There’s only so much you can pack into an eyebird.’ She raised her hand up in front of her face. The slim lines of an OCtattoo materialized across her skin, as if her veins were being invaded by quicksilver. ‘I need to get a bit closer for a decent readout. I don’t want to desecrate anything the way those riders have.’
‘Where does the herd get metal from?’ a puzzled Dino murmured.
‘I don’t know. But it’s got to be valuable to humans somehow.’ She couldn’t think how. ‘Maybe an alien starship crashed nearby, and they’re picking up the wreckage.’
‘Is that likely?’
‘Not really,’ she admitted. ‘We’ll have to get down there to find out for sure.’
‘We can’t risk getting caught,’ Dino said. ‘The herd’s upset enough as it is.’
‘Are they heavy sleepers?’
Before Dino answered, eyebird six sent an alert; several solid objects were airborne below it. They weren’t large, and they didn’t rise quite high enough to strike it. They fell back to the ground, but not before the next barrage was rising.
Paula looked directly through the eyebird’s camera. A dozen or so Onid were clustered below it, flinging stones. She hurriedly instructed it to raise altitude. When it was thirty metres above the ground, she paused it. The Onid were still there, still throwing stones. More were joining them. Their hoots of alarm were slowly crossing the valley.
‘How the hell did they see it?’ she asked incredulously. ‘It’s silent, the fan balances on superconductor bearings, and the colour is dehanced-grey.’ She glanced up at the clouds scudding past the mountain peaks. ‘It’s practically impossible to see it against a sky like this. Do they have some kind of ultra-vision?’
‘No,’ Dino said. ‘Their eyesight isn’t even as good as ours.’
‘Then how…’
‘I don’t know.’ He looked back towards the edge of the forest. ‘We really need to know what’s in those graves.’
Paula focused back on the images from eyebird six. There were twenty Onid below it, scraping stones from the ground and flinging them up. She instructed the eyebird to fly slowly down the slope towards the fast river at the bottom of the valley. The Onid followed it as if it was their guru. ‘How?’ she whispered. The question would have to wait, this provided her with a perfect tactical opportunity. She quickly directed four other eyebirds to join up with number six, sending them low over the ground, weaving about so they passed close to various batches of Onid. After half an hour, with the creatures’ hoots and squeals echoing across the valley, the five eyebirds were together in a loose V formation. Below them now, and still hurling their ineffectual missiles, were over a hundred Onid, with what looked like every other member of the herd heading across the valley towards them.
The eyebirds drifted towards the end of the valley and the forest beyond. Holding station five hundred metres above them, the remaining three eyebirds watched the burial ground and the surrounding land. It was now devoid of any Onid.
‘If they were sentient they would have left guards,’ Dino said as they rode out of the forest close to the burial ground.
‘Yes,’ Paula conceded. Hurdy trotted along the base of the cliff, keeping to the thick shadow it was throwing. If the Onid did have poor sight as Dino claimed, they’d be hard to see in such shade. Even so, she eyed the fissures in the grey rock warily, holding the carbine ready for any ambush.
They dismounted as soon as they reached the first of the little mounds. The silver lines of Paula’s OCtattoo appeared again over her hand, spreading a delicate lacework back down her forearm. She knelt beside the first grave, and slowly waved her hand over the wispy grass-equivalent.
The results of the scan materialized in her virtual vision, tight bright graphics superimposed over what she was seeing. ‘Holy crap,’ she gasped.
It wasn’t difficult to track the riders’ trail across the open grassland. Paula and Dino took four hours to reach the thick woodland it led into. She sent another small flock of eyebirds flitting through the trees as they walked forwards cautiously. The airborne sensors scanned round for any sign of human activity. Three more of the little gadgets zoomed high above the wood, which produced an almost immediate result. The trees were crowded around
