'I wondered when you'd realize that,' said the Doctor.

'What are you going to do about that?'

'Something,' replied the Doctor.

Galatea made the final reversal in the equation. The hologram disappeared.

She heard the Hive shriek in anger, hunger and defiance.

The Darkness prepared its next movements. It would release two Clouds.

The first would kill as many beasts as it could and carry their meat up to be shared out. The second would take one of the dead beasts, inhabit its form, and then locate the transmat.

The Clouds a.s.sembled, and outlets were formed in the lower coating of the Hive.

And then the world outside winked out, and the Darkness was suddenly alone and so cold. Its intelligence tried to comprehend what had happened and could not. Its sense of itself fizzled out. It became nothing more than a collection of molecules.

STOKES, Menlove: born c. 2542 - d. ??? Professor of Applied Arts at St Oscar's University, planet Dellah. Exhibited widely. Corney Debrette Oscar's University, planet Dellah. Exhibited widely. Corney Debrette described him as 'at the forefront of the essentialist movement of the late described him as 'at the forefront of the essentialist movement of the late twenty-sixth century; a truthful and influential voice.' twenty-sixth century; a truthful and influential voice.'

Stokes slumped back from the screen, feeling as if he'd been punched. 'A truthful and influential voice,' he said to himself. Then he started to laugh maniacally. Strang, Anderson, Oddstock, all forgotten. Not even a whisper.

But he was in there. He'd never heard of Dellah, or Corney Debrette,and his previous life had ended. in 2386. But he was standing in a time machine. So he had a future - and what a future! - waiting in the past.

He wagged an accusing finger upwards. 'It didn't work, then,' he cried. 'He gets away, and we go back there together. It's all been a colossal waste of effort on your part, hasn't it, rather?'

And then, whether from the exhaustion of the previous couple of hours or for some other reason, his legs vanished from under him and he was toppling and tumbling down what seemed like a high, steep hill.

The tension in the valley was palpable. All eyes were on K9 as an almost imperceptible sequence of clicks and whistles came from his voicebox. The Doctor was hunched protectively over him, perfectly still, his concentration absolute. Romana knelt on the other side, her fists clenched tight.

K9 spoke at last. 'Galatea reports the expulsion has been successful.'

The effect of his words was like an explosion. There was a general round of cheering, applause and back-and sh.e.l.l-slapping. Romana jumped up with relief and found herself grabbed by Fritchoff: 'We did it!' he cried. 'We did it.'

'Yes, we we did,' she said, disengaging herself. She turned back to the Doctor, who alone of the group remained still. His head had fallen forward on to K9's muzzle and his eyes were closed. Romana supposed at first that the strain of the last few hours had weakened him, but then she noticed that he was still absolutely poised. did,' she said, disengaging herself. She turned back to the Doctor, who alone of the group remained still. His head had fallen forward on to K9's muzzle and his eyes were closed. Romana supposed at first that the strain of the last few hours had weakened him, but then she noticed that he was still absolutely poised.

She laid a gentle hand on his still-wet shoulder. 'Everything's all right, isn't it?'

'Perfectly.' He lifted his head, and there was an unaccustomed bitterness in his eyes. 'Yes, we've seen them off very easily. Very easily indeed.' He bit his lower lip. 'And I've thought of an answer to your question, by the way.'

She nodded. 'You're going to suggest locating the Hive's energy signature on the transmat line and reverse-phasing it into a stable relational zone using the TARDIS.'

He stood up. 'Am I that predictable?' Without any of his usual humour he signalled grandly to the people standing around him. 'My work here is done. You've got a planet to reclaim.' He pointed to the shuttle. 'A few trips should get you all back there. Just reverse the transmat coordinates back again and you can get your people back from Regus V - it's all very simple.

Ask Galatea, if she's still up and about.' To the Chelonians he added vaguely, 'And there's no reason why you shouldn't integrate now, is there?'

With a final nod he started to walk away.

Romana, appalled by his bad manners, raced after him and grabbed the elbow of his coat. 'Doctor. Don't you think you ought to say goodbye?'

''I thought I already had.' He turned abruptly and nodded to General Jafrid.

'Take care. Try not to jump to too many hasty conclusions in future.'

Jafrid spread his front feet wide. 'Doctor, I have already indicated my profound regret.'

The Doctor cut across him rudely. 'Yes, yes, it's always very easy after the event. You know, just once it would be nice to meet a member of your race who didn't want to try to kill me.' He moved now to Harmock. 'You're the politician fellow, are you?'

'That's right, yes,' said Harmock. 'I am the Premier of Metralubit.'

The Doctor said curtly, 'You were a powerless plaything. Now you're going to have to live and work in the real world. I wish you luck, and with your professional background you'll need it.' He crossed to Fritchoff: 'Well, thank you for your help.'

Fritchoff beamed: 'Doctor, when the history of the rebel militant movement is written, you will have a special place.' He shook the Doctor's hand but his eyes kept flicking to Romana.

Noting this, the Doctor turned to Harmock. 'Premier, there are females down in your dome, aren't there? Real ones, I mean?'

Harmock nodded enthusiastically. 'Yes, plenty.'

'Good.' He pointed to Fritchoff: 'Try to find him one.' He beckoned to Romana and K9. 'Now, we really have to go. There's the Hive to deal with.

We're not out of the woods yet.'

They followed him. K9 said, 'There is no forest in this vicinity, Master.'

'Shut up, K9,' said the Doctor.

Following their departure there was another strange silence in the valley.

'Well,' said General Jafrid. 'Right,' said Harmock.

Fritchoff stepped forward. 'First of all, we have to settle the Barclow dispute.'

Jafrid made a conciliatory gesture to Harmock. 'You can have it.'

Harmock made a similar gesture in return. 'No, you can have it. I insist.'

'Secondly,' said Fritchoff, 'and before any decisions are taken on the future of Metralubit, we must discuss and refine in detail the exact nature of the administrative and economic system that will act as the underlying base for those decisions. I move that we orientate ourselves to a socially liberal but state-regulated internal market.'

Harmock shook his head emphatically. 'No, no, no. If we intervene in the affairs of ordinary people as they go about in the reclaiming effort, where will it end? This is a most woolly-minded scheme, Mr Fritchoff:'

'My position is the very opposite of intervention,' said Fritchoff. He waved at Cadinot and the others. 'You're just trying to mould the minds of these people by exploiting their fears for the future, and thus imbuing them with a false consciousness in relation to their position with capital.'

Jafrid coughed loudly, drawing their attention. 'Please,' he said. 'This debate is going nowhere. There is only one course left open to us now.'

And what's that?' demanded Harmock.

'We must take a vote,' Jafrid said simply.

Chapter Twelve - The Official End Of It All.

Stokes dreamt.

A voice, deep and granite-hard, was ordering him to wake up. The deal was not yet done.

Stokes resisted. The appreciation he'd received on Metralubit had been a sham. Why should he listen to the voice again?

The voice reminded him what the screen had shown. He would be appreciated on Dellah. Would he like to go there?

Stokes pondered. Was that possible?

The voice a.s.sured him it was. All he needed to do was set the correct s.p.a.ce-time coordinates on the TARDIS's navigation panel.

Stokes laughed at this. The workings of the TARDIS were quite outside his understanding.

The voice told him it could lend a guiding hand.

And so Stokes woke up, and found his hands wandering over the navigation panels as if he'd been piloting the TARDIS for years.

The data-bank screen now read: DEPARTURE -BARCLOW Humanian Era DESTINATION - DELLAH AD 2593.

Romana was perturbed. The Doctor was pounding back to the TARDIS, hands thrust deep in his pockets, head down, hat pulled over his face, leaving her and K9 to struggle to catch up. The rain was falling again, whipping her cape out behind her and knocking K9 off his bearings from time to time.

'Do we have to go quite so fast?' she protested to the Doctor's back. It was the first time they'd spoken since leaving the survivors of this affair in the valley.

'Why break the habit of several lifetimes?' the Doctor grumbled. 'I must have spent the greatest share of my time since leaving Gallifrey running up and down with barely time to stop and think.'

Romana recognized the signs of impending moodiness and felt rea.s.sured.

She could cope with these occasional bouts of brooding. 'I do hope you're not going to start feeling sorry for yourself.'

He stopped and turned to her. 'That would be predictable, wouldn't it?'

His tone was almost aggressive, and for the first time ever in his company Romana felt threatened. 'Please don't shout at me.'

He looked between her and K9 and managed a tight smile. 'Do forgive me.

It's just that I'm worried, you see.'

'About what?'

He stepped closer and his grave expression returned. 'When you can predict a person's actions it's very easy to lay snares for them.'

K9 whirred impatiently. 'Query these deliberations, Master. We should return to the TARDIS and continue our travels.'

The Doctor looked down at him. He was silent for a moment and then he burst into one of his sudden crazes. 'Yes,' he shouted, 'planet saved, crisis averted, evil menace vanquished. All the questions answered, everything wrapped up.' The sky rumbled as if in reply and another gust of freezing rain swept over them.

'Situation has been resolved, Master,' said K9. 'The people of Metralubit and the Chelonians can exist together. The Hive has been banished.'

Romana laid a comforting arm on the Doctor's shoulder. 'K9's right, Doctor.

I don't see what there is to fret about.'

He walked a short distance away and stared out into nothingness. 'From the moment we arrived here I've felt a powerful unease.'
