dock key up to the verifier panel and held it there while
   poking his little finger into the biosampler slot.
   Something moved outside, occluding the light from
   the nearest dock flood, then suddenly it loomed closer
   and collided with the tube.
   'Does it usually take this long?' said Drazuma-Ha*,
   now poised quite close by.
   Kao Chih glared at the machine. 'Is that another of
   your predicaments? - look, it's trying to cut its way in!'
   A metre or two back from the airlock, the tube's heavy-
   grade material was being pinched. Kao Chih stared at the
   deforming plastic with panic and a growing sense of unre-
   ality enhanced by the hammering sounds coming from
   the access port at the other end of the tube. Then to his
   vast relief the verifier panel beeped and the airlock hatch
   slid open. Courtesy was not uppermost in his mind as he
   dragged himself in round the edge of the coaming, closely
   followed by the mech. Once they were inside he punched
   the hatch button and a moment later they were sealed off.
   'Show me to the pilot controls,' the mech said. 'We
   must leave immediately.'
   'This way,' Kao Chih said. 'But why the haste now
   that we're safe?'
   As they reached the main console he heard distinct
   hard knocks and thuds coming through the hull.
   'Who are those droids?' he muttered. 'And what do
   they want?'
   'Collectors,' said Drazuma-Ha*. 'Chasing an old
   debt. A moment, please.'
   Microfield extensors sprang out from the mech's aura
   to the console, connecting with several interface ports.
   Readouts and symbol telltales flickered in waves across
   the cockpit and one of the auxiliary screens unfolded
   from its niche to reveal an exterior shot of the
   Castellan's hull, underneath, near the midsection. A
   strange, angular machine crouched there on several
   articulated limbs, reflected light from further back cast-
   ing it in silhouette. A second screen showed the other
   two droids now in the access tube and making cumber-
   some progress towards the airlock. Then a faint whining
   noise came from underfoot, beneath the deck.
   'It's drilling through the hull,' Kao Chih said, striving
   to stay calm.
   For a moment the mech made no reply, then:
   'All is ready, Gow-Chee - shall we depart?'
   'Without delay!'
   The Castellan gave a lurch and suddenly he realised
   he should have been strapped in. Hurriedly he did so
   while keeping most of his attention on the exterior dis-
   plays. The access tube had unfastened from the airlock
   and was retracting into its housing with the two droids
   still holding on. The third still clung to the ship's under-
   side and the drilling sound continued unabated. On the
   screen, the jumbled shapes and structures of Blacknest
   receded as their reaction thrusters burned a departure
   trajectory.
   'We will soon be far enough away for a safe jump
   into hyperspace,' the mech said. 'But there is a problem.'
   'What kind of problem?' Kao Chih said hoarsely.
   'The hyperjump course data I obtained from Avriqui's
   system is supposed to take us to Bryag Station near the
   Indroma border, but the value set is several hours out of
   date. Clearly he meant to recompile it just before depart-
   ing with you and your deceased companion . ..'
   Kao Chih's heart sank. 'We could emerge inside a sun
   or a planetary atmosphere ...'
   'No, not with the safety features built into this vessel,'
   Drazuma-Ha* said. 'We would be safe from such perils,
   including the one currently attached to our hull - it would
   detach itself the moment the hyperdrive initiated its first
   phase. But our destination will be indeterminable.'
   'And if that breaches the outer hull, we're finished.'
   Kao Chih gripped the arms of his couch. 'Do it!'
   'You're certain?'
   'Just do it now!'
   The shield layer rolled across the viewpane and he
   murmured a brief prayer to his ancestors as the hyper-
   drive gathered all its forces and hurled the Castellan
   into the void.

   GREG
   He was almost a dozen metres down the southern face
   of Giant's Shoulder, shivering in a cold night breeze,
   when his comm chimed. He called out to Teso and
   Kolum, his Uvovo accomplices, to stop lowering, then
   answered the call.
   'Greg Cameron here.'
   'Hello Greg, it's Catriona. Just thought I'd call you
   before the shuttle leaves.'
   'Ah, thanks Cat, that's, um, very thoughtful of you.'
   'So, what are you up to this evening? Sounds like
   you're outside ...'
   'Oh, just studying some pillar carvings, y'know,
   trying to figure out if they're ritual or ceremonial ...'
   He felt himself break out in a cold sweat, more from the
   gnawing sensation of vertigo, suspended there in the
   high darkness with a handilamp hanging from his neck,
   lighting up the rock face right in front of him.
   'Just a moment,' said Catriona. 'Are you ... dammit,
   you are! - you're climbing down the side of Giant's
   Shoulder in the middle of the night. Are you completely
   insane?'
   Greg sighed. In the aftermath of the shooting yesterday
   he had showed Catriona the scans revealing the passages
   and chambers beneath the temple, and together they had
   started planning how to reach the opening that led inside.
   But Cat had been ordered back to Nivyesta, leaving Greg
   to pore over the scans and and an assortment of pictures
   of Giant's Shoulder dug out of the files. Then came news
   of the bombings, which seized his attention for the rest of
   the day.
   'Look, I'm fine, I'm safe, the equipment is the best
   and I've got friends helping me,' he said, exchanging
   waves with the two Uvovo smiling down at him. 'I'm
   more worried about you, to be frank.'
   'I'm okay. Did you get hold of your mother and your
   brothers?'
   'I did, and they're all well - no one was anywhere
   near Founder Square or the Ros Dubh sports centre,
   but there's been no word from Uncle Theo since yester-
   day ...'
   'Greg, I just wish you'd give up this midnight expedi-
   tion and wait for daylight.'
   He smiled, thinking - Ah, she really does care. Things
   are looking up.
   'Och, don't worry, Cat,' he said, i'm strapped into a
   body harness with about a thousand D-rings and plenty
   of that Uvovo heavy-bearing line . ..' He gave the line a
   playful tug. 'Safe as houses . . .'
   Which was when the composite strap junction at his
   back snapped. He yelled as he swung to the right and
   down, head dipping. Through his cold terror he was
   aware of his lamp slipping off and falling away into the
   blackness, but most of his attention was on trying not to
   slip out of the loops that still gripped his legs and left
   arm. The two Uvovo called down in fearful voices but
 &nb
sp; he tried to reassure them - then cursed when he realised
   that he had dropped his comm. By now he had worked
   himself into a more upright position, holding on to the
   safety line with a gloved hand.
   Gods, Cat was right! I must be mad to be doing
   this . . .
   He glanced down and started to tell the Uvovo to
   haul him up, then paused, staring at a faintly glowing
   spot on the rock face a few feet below. He stared, held
   his breath and listened . . . and, just on the edge of audi-
   bility, heard a tiny voice calling his name. Catriona! He
   laughed shakily - his comm must be lying on a ledge or
   in the tangle of a cliffside bush - and shouted to her to
   wait a minute or two. Quickly, he rigged the loose
   strapping onto the safety line with toothhooks to take
   some of the load off the damaged strap junction, then
   told the Uvovo to lower him. Slowly he descended
   towards the glow, which he now reckoned might well
   be sitting in a niche in the rock. Then he came level
   with it and saw his comm, resting in a tangle of dry,
   dead roots that spilled out of a sizeable gap in the cliff
   face.
   Reaching in he grabbed it and saw that Cat had dis-
   connected. Quickly he sent a note saying that he was
   okay, then activated the comm's little torch and shone it
   inside the opening. He stared in surprise for a moment,
   then chuckled - beyond the opening was a small pas-
   sageway sloping down towards the front of Giant's
   Shoulder. The opening was just wide enough to crawl
   into, which he did, pausing halfway in to undo the har-
   ness then shout to the Uvovo to pull it up. When he
   told them he was exploring a cave they became agitated,
   imploring him to return.
   'I'll be perfectly safe,' he yelled back. 'Just get the
   replacement harness from stores and listen out for m .'
   'Old places are dangerous, friend Greg,' came Teso's
   strained reply. 'Please be very careful.'
   'I will be, don't worry!'
   Then he turned his attention to the passage. It was
   quite narrow and low, just a little over average Uvovo
   height. The walls were smoothly worked with even
   curves, as was the opening through which he had
   entered. Shining his torch further down he could make
   out another similar aperture, but choked with coils of
   redthorn as well as the decaying detritus of dead plants.
   This had to lead to the opening he had seen on the
   Heracles scans, and which he had intended to find
   tonight.
   Perhaps this will be safer than hanging about in the
   air, he thought as he tugged out his forest blade and
   attacked the tangle of vegetation.
   The passage went on for another ten metres or so,
   blocked at regular intervals by bushes or creepers that
   had taken root in the soil-caked floor near the open-
   ings. He was sweating freely by the time the passage
   turned back the other way: the water-worn vestiges of
   steps were just visible under the layers of dirt and decay.
   Insects glimmered and settled in the slim beam of his
   comm-torch, which chimed just as he started hacking at
   another wall of desiccated twig. It was Cat. He took a
   deep breath and answered.
   'Hi, Cat!'
   'Right, what the hell happened?'
   'Eh, nothing serious, just juggling with my comm . ..'
   'Dammit, Greg, I... was worried ...'
   He heard the catch in her voice and instantly regret-
   ted the offhand remark.
   'I'm sorry, Cat, I'm okay, just had a wee fright when
   a clip broke. But I rigged a repair and I'm now inside the
   rock face of Giant's Shoulder and making my way down
   a passageway.'
   'Is it safe?' she said. 'What does it look like?'
   He gave a brief description and assured her that he
   was not in any danger.
   'Aye, well watch out for doubletails - they nest in
   dark, dank places.'
   'And they're usually found further to the north than
   this,' he said. 'But I will keep my eyes open, I promise.
   When's your shuttle flight?'
   'Less than an hour.'
   'I'll call you when I reach the opening,' he said. 'Or
   wherever this is leading to.'
   After murmured goodbyes, he thumbed the torch
   back on and resumed chopping away dead foliage.
   Another thirty-odd minutes later he had hacked, kicked
   and torn his way through several barriers of roots,
   creepers and bushes, most of it dead growth. His exer-
   tions had raised wafts of dust which clung to his clothes
   and hair, working its way into the creases of his hands
   and face - he felt indescribably grimy and often coughed
   in the hazy gloom. But beyond the last clump of vegeta-
   tion he came to a level landing and a large square door
   in the rock. Opposite the door was a semicircular
   window that was blocked by a curtain of heavy-leafed
   creeper, some of which had spilled inside.
   Beyond the dark threshold of the door was a pitch-
   black corridor. With his torch lighting the way, Greg
   followed it inwards for about twenty paces before
   encountering a double row of pillars that completely
   blocked the way. The pillars were square and the rows
   were set close together in a staggered formation that
   obscured what lay further on. Frowning, he called
   Catriona.
   'Took ye long enough,' she said.
   'I've been doing a bit of pruning,' he said. 'Have you
   ever seen square pillars in a Uvovo building?' As he
   spoke he took out a small field cam and took a few pic-
   tures.
   'No, never.'
   'Well, I'm looking at some now.' He described them
   for her, then examined their tops and bottoms. 'The dirt
   and dust buildup is solid around the bases but up at the
   ceiling there's a definite gap, as if the pillars slid down -
   maybe this is some kind of primitive stone portcullis . ..
   wait a second, what's that?'
   After probing the gap around one pillar he had
   pushed it to see if there was any give, and immediately a
   sequence of four glowing symbols had appeared on its
   face, one by one down its length, and faded away. A
   moment later the sequence repeated itself and he swiftly
   took more pictures while describing what was happen-
   ing.
   'What do the symbols look like?' Cat said.
   'Nothing like any of the glyphs that the Uvovo use,
   now or in the past.' He bent down for closer study.
   'They're composed of straight and curved lines, some
   crossing others, some not.'
   'Could be ideograms,' she said. 'But what kind of
   technology can embed glowing characters in stone and
   still be functioning thousands of years later?'
   'Aye, those ancient Uvovo sure had a few tricks up
   their sleeves . ..'
   Suddenly there was more light in the passage as sev-
   eral triangular symbols lit up on the adjacent pillar.
   'Why have you gone quiet? Greg, what's happening
   now?'
   'Seven triangles have appeare
d on the next pillar ...
   wait, the one at the bottom has gone out so there's
   six ...'
   'Hmm, odd. Has it come back?'
   'No, and another just went out, the top one, when
   the four symbols went through the sequence.'
   'Hang on, the Uvovo use the triangle to symbolise an
   imperative demand for an answer so those other four
   ideograms ... must be some kind of question you have
   to answer before all the triangles are gone ... I think . . .'
   'So how do I answer the question?'
   'No idea - how many triangles are left?'
   'Two.'
   'Get out of there, Greg, now!'
   He dived away from the pillars and dashed for the
   entrance. As he did, a rumble came from the surround-
   ing rock then cracking sounds and a cluster of heavy
   impacts. Dust billowed out and settled on his shoes and
   trouser legs.
   'Greg, are you okay?'
   'I am,' he said. 'And now I'm going back inside for a
   look.'
   if I could reach through this comm . . .'
   'There're more pillars, Cat, about fifteen paces in this
   time.'
   The new obstruction was identical to the first but
   pristine, no windblown dust or dry leaf fragments nor
   insect remains.
   'Don't touch it, Greg - in fact, don't even go near it.
   Promise me you'll go back up and wait till morning.
   Then you can speak with Foyle at the Institute and get
   hold of one of the Listeners to see if they recognise those
   symbols.'
   'Aye . . . okay, Cat,' he said, retreating to the
   entrance. 'Maybe you're right. I'll head back up top,
   get some rest.'
   'Good, you sleep well and I'll... send you a message
   when I'm home.'
   'Okay, safe flight.'
   For a few moments after the line disconnected, Greg
   stood there, smiling thoughtfully, wondering where this
   thing with Catriona was going - if it actually was going
   somewhere. Then he shrugged.
   Hard to be sure now that she's away back to
   Nivyesta, he thought. As for this puzzle ... perhaps I'll
   wait for Chel, see what he thinks of those symbols, and
   when I've got something solid, then I'll tell Foyle at the
   Institute ...
   He shone the comm torch back along the corridor
   one last time, peering at the pillars in the dimness. Then
   he saw something he hadn't noticed before, that the
   walls were covered in the familiar Uvovo raindrop pat-
