Part 17 (1/2)

He turned to look greedily at the case in the robot's hand. 'Oh that's it, is it, the secrets? My word there should be a nice lot in there. All on micro dots, no doubt... Come along then Dibber, open the door for the Immortal!'

No sooner were the unlikley trio out of the door than the Doctor had slipped his bonds and was releasing Peri and Merdeen.

'Quickly, you've both got to help me. There's a three-stage cut out. I've got to try and shut the machine down.'

'Will that prevent an explosion?' gasped Peri.

The Doctor shook his head. 'All I can hope to do now is contain it.'

By now all three were at the black-light console. The Doctor was making complex adjustments to the controls.

The console was vibrating and smoking, almost too hot to touch.

'Peri, you press that row of b.u.t.tons in front of you!'

ordered the Doctor.

Peri looked down. 'Which ones?'

'All of them! Merdeen flick up all the switches with red neons on them.'

Merdeen looked bewildered. 'Red what?'

'Show him, Peri!'

'How much time do we have?' asked Peri.

'Not a lot!' The Doctor was heaving at a lever on the back of the console. 'This thing hasn't been moved in centuries...'

Between them Peri and Merdeen completed their tasks.

'Now what?' asked Peri.

'Get out of here, both of you!'

'What about you, Doctor?'

'Just go. Merdeen, take her out.'

As Merdeen dragged the protesting Peri away, the Doctor heaved the ma.s.sive lever across at last, adjusted more controls.

The machine was making a strange howling noise. 'Oh dear,' said the Doctor. 'Well, I did my best. I only hope its enough.'

As he turned and dashed out of the control room, it exploded in smoke and flame behind him...

14.

End and Beginning Still wiping the green slime from his face, Balazar was moving cautiously towards the Castle. The force of the explosion in the control room knocked him off his feet.

Dibber and Glitz had escorted the staggering robot as far as the bottom of the steep metal steps. It was weakening all the time and they were wondering how soon they could risk getting the metal case away from it and heading for their s.h.i.+p.

They heard the thunder of the explosion. The robot staggered and the suddenly began to heat up, giving out a strange howling sound. Soon it was radiating heat, and glowing cherry red.

'Look out,' yelled Dibber. 'It's blowing up!'

Dibber and Glitz dived for shelter.

There was a kind of internal explosion and the robot seemed to collapse inward upon itself. Soon the glow faded and there was nothing left but a long puddle of molten metal. Dibber got up and moved to examine it.

Glitz, who had rolled himself into a ball in the corner, unwound himself and looked up. 'Is it finished?'

Dibber nodded sadly. 'You're not going to like this, Mr Glitz,' he said lugubriously.

'The robot's finished, and the secrets are finished as well.'

Glitz jumped up. 'What?'

The exploding robot had fused the metal case into a misshapen lump, welded to the remains of the robot's body.

'Still, there's this,' said Dibber casually.

He took a small s.h.i.+ny lump of metal from his pocket.

'And what's that?'

'A piece of black-light convertor aerial,' said Dibber. 'I picked it up when I blew the thing up. Pure siligtone that is.'

'The hardest known metal in the galaxy,' said Glitz.

Dibber nodded. 'And the most expensive. What's more, there's got to be a couple of tons of the stuff in that aerial.'

'I am way ahead of you, my son,' said Glitz. 'You know, we could clean up very nicely on this job - and have a tasty little kitty for the next venture...'

Dibber set off up the stairs.

Glitz paused for a moment looking after him. He'd just been struck by a very worrying thought.

Suppose it was Dibber who was the brainy one after all?

Humker and Tandrell reached the surface at last. They stood looking out of the doorway and something clear and cool came in to meet them, ruffling their hair.
