He was certain that the ungainly monster he"d seen had something to do with Arden"s excavations at the glacier face; and there had only been one way to satisfy his questioning mind: go and investigate.

Penley lurched forward through the drifting snow, moving diagonally across the slope that would bring him close to the excavation site. But at the top of the wind-skimmed ridge, he paused and crouched, his eyes squinting into the wind, hardly able to believe what he saw.

The usually smooth curve of the glacier, instead of gleaming dully in the fading moonlight, glinted and sparkled like a frozen waterfall. In front of the shattered crystalline wall, ankle deep in ice fragments, towered the alien creature.

Its arm was pointed at the ice face and, even at this distance the whine of some unseen device could be heard, faint but jarring to the ear. And as Penley watched, great frozen gouts of ice spurted and crumpled away, as though struck by a gigantic, invisible hammer! The creature was carving its way into the heart of the glacier!

Penley shaded his eyes and peered harder into the stinging spume of snow. Now he could make out the girl-

apparently helping, though without much enthusiasm. But it was what stood beyond, gaunt and gleaming in the thin light of the dying moon, that caught Penley"s eye and held it in unbelieving amazement. Like prehistoric stone monoliths.

carved and dragged from the face of the glacier, towered four immense blocks of ice.

At last the searing whine of the sonic weapon ceased.

With a series of great heaves. Varga tore the last remaining block of ice free of the glacier, and dragged it across to the others. The five gleaming crags loomed menacingly against the night sky: Victoria seemed to flinch from their cold power. Varga strode proudly up to them, and struck the fractured ice with his great fist.

"It is done," he hissed, elated. "They are free!"

He wheeled to face Victoria, and snapped out his orders. "Bring the power packs to me!"

She could do nothing but obey. s.n.a.t.c.hing them front her, he deftly placed the electrodes at key points on the first two blocks of ice. They began to hum ominously. Varga faced his comrades boldly, and barked a command at their lifeless forms.

"Awake from the dead!"

5.

The Omega Factor Dawn at last. Outside the Base airlock, the equipment that Arden and Jamie would need for their investigation was already packed aboard the sleek form of the airsled. It included all the usual snowtrek survival gear; drilling tools, power packs and self-heating food dispensers. But most important of all was the directional radiation detector, which would locate and identify any potentially dangerous fissionable energy source in the glacier. Both Jamie and Arden were eager to set off, but Clent had insisted the standard formality of departure briefing. Jamie stamped his feet impatiently as he spoke to the Doctor.

"Does he always have to do everything by the rule-book?

Why doesn"t he just wish us luck and let us get on with it!"

The Doctor shrugged. Clent was too complex a person to explain easily to someone as young and direct as Jamie.

"Forget about Clent, lad, and concentrate on being careful..." Then he added thoughtfully, "Keep an eye on Arden, too. I don"t think he quite realises how dangerous that creature is."

Jamie knew that well enough, and wasn"t afraid to admit is "After what happened in the laboratory, he must be blind then!"

"He is a scientist, after all," murmured the Doctor, his eyes glinting mischievously. "You know what they"re like."

Jamie caught his glance, and chuckled, remembering what he"d had to put up with from the Doctor in the past.

"Aye! I know that all right!"

The briefing over. Arden was eager to leave. His enthusiasm bubbled over as Clent followed him through the airlock door.

"I hope we"ll at least get a chance of taking a film of the warrior!" he blurted out boyishly. "Mind you-we"ll have to tread carefully. We don"t know how many more of them will turn up."

"I don"t want you exposing yourself to unnecessary risks.

Arden-remember that!" replied Clent crisply.

Arden paused and faced Clent, his face sober. "Listen, Clent, we both know that I"m responsible for what"s happened-as well as Davis"s death. I"m not likely to be that stupid again, believe me!"

Clent didn"t reply immediately. They both knew that if a dangerous power source was discovered in the glacier, Arden"s archaeological adventure would in fact have saved Clent and the Base from complete annihilation. If the warrior had been left in the ice, no one would have been wise to the possible danger.

"Just get that information back to Base," insisted Clent.

"And no desperate attempts to rescue the girl. She"s the least of our worries: "Well I"m no leaving Victoria to that creature up there if there"s half a chance of saving her!" snapped Jamie, who had heard the last remark.

"You will take your orders from Scientist Arden!" replied Clent, and disappeared through the door before Arden and Jamie had stepped into the airlock-and from there into the Arctic world outside. Once the temperature-sealed door had closed, even the Doctor couldn"t hear the whine of the airsled as it skimmed across the snow towards the glacier. He turned and followed Clent back to the main building.

Clent was waiting for him in the corridor.

"Come along, Doctor," he said genially. "Time for you to show us what you can do."

The Doctor forced a smile. He would much rather be with Jamie on the way to the ice face-but for now at least, his immediate purpose lay in unravelling the mystery of the Ioniser malfunction. It had to be prevented from happening again. "By the way," he asked, "what was Penley working on when he left?"

The Doctor noted the effect of his question with interest.

Clent glowered and looked the Doctor in the face. "That information is top secret." Turning on his heel, he brusquely led the way inside.

Storr thumped the table top angrily. "A creature carved out of the ice! It"s you that"s been in a coma!"

"I"m telling you-it was teal, and terrifying. And I"m not one for fairy stories-any more than you are. If I"d only seen it at the glacier, I"d agree with you. But it was inside the Base as well."

Storr stared at him. "Leave me out of your fun and games, then!" he growled. "I"ve got enough to cope with."

"You"re certainly back to your old cheerful self," said Penley-and then stopped. "What"s the matter?" Storr moved swiftly towards Penley, and whispered into his ear. "Someone"s outside. Not an animal-human. Trying to get in!"

"They must"ve tracked me back here from the Base.

Quick-hide yourself. We don"t want you carted off to Africa vet."

In a second, Storr had hidden himself, and Penley was to all intents and purposes alone. Satisfied, he moved to boldly confront the intruder-and stepped hack in surprise at the sight of Jan Garrett when he drew back the interior screen.

Penley"s eves glanced quickly behind Jan. She shook her head.

"It"s all right-I"m alone."

"Well, now you"ve followed me here, what do you want?"

She had moved farther inside; the screen fell back across the doorway.

"Elric..." It was months now since anyone had called him by his first name. Jan had been his equal then: a genuine friend who showed some understanding of and sympathy for his clash with Clent-but not, he remembered bitterly, a fellow protester. Miss Garrett was too ambitious for that.

"You haven"t forgotten my face then, Miss Garrett," he said politely. He glanced at her lapel. "No orders of merit yet?

Not even for trying to cope with that stupid machine."

"You"re the only one who ever understood it," she answered bluntly. "We"re in desperate trouble-help us!"

"Us? Does that include Clent?"

"He doesn"t know I"m here."

"I was going to say-he"s the last person to need me me! All he needs is a mirror-preferably rose-tinted and of the magnifying sort"

"He"s ready to admit... that you have the knowledge he requires. He needs you-it"s the only way he can be sure that the Ioniser will be permanently stabilised."

"I"m surprised it hasn"t already run wild, to tell the truth. Especially when I heard the evacuation broadcast.

Some fluke saved him, I suppose?"

"A stranger came. He"s eccentric-and infuriatingly like you. He doesn"t think much of computers," she added.

Penley smiled as he remembered the clownish intruder he"d met over Clent"s unconscious body. "Good for him!"

"But he doesn"t know it all!" protested Jan. "Only you know all the imperfections of Ioniser theory-even this stranger says it needs an expert!"

"And what does Clent say?"

"You know how proud he is. But his back"s to the wall.

Sooner or later he"s going to have to make his report to the World Authority..."

"So sooner than have to admit failure, he"d like back so he can produce a scapegoat! No thanks-let him face the music himself!"

"It was never easy. It"s ten times worse now. Arden"s made a fantastic discovery in the glacier." She took a deep breath and stared at Penley. "Aliens."

To her surprise, Penley didn"t even smile. He leant forward, his eyes keenly interested. "Of course!" he exclaimed.

"it must be alien! That thing could never be an earth hybrid or a throw-back!" He saw her look of surprise. and explained, "I"ve seen it, you understand, at close range-working at the ice face, blasting great chunks free!"

There was a small silence before Jan spoke again; this time her voice sounded strained. "We think there may be an alien s.p.a.ceship buried inside the ice," continued Jan, "and if it contains a nuclear power source..."

She didn"t need to say any more. But Penley"s brutal answer shook her.

"Then Clent"s got no option, has he? He daren"t use the Ioniser any more. He"ll have to evacuate!"

Jan"s anger flared. "You know what"s at stake! Five thousand years of civilisation! Clent won"t give that up-none of us will! Even you can"t deny what we"re here for!" She paused, trying to control her anger. "Doesn"t our civilisation mean anything anything to you?" to you?"

"I know what it means to Clent!" replied Penley sharply.

"It"s a computerised ant heap! Well I"m a man-not a machine! I"d sooner live with the Ice Age than with his his sort of robot universe!" sort of robot universe!"

He paused for breath. Jan took out her tranquiliser gun and pointed it straight at him. "You most be desperate," he remarked. "But it"ll do no good. You"ll never manage to carry me even as far as your airsled."

"I"m willing to try," she said, then yelped with pain as Storr knocked the weapon sharply from her numbed hand.

She turned, stared at Penley"s savage-faced companion, and drew back nervously, holding her wrist. "Who... are you?" she whispered.

"A friend," said Penley, picking up the gun before Storr could reach is "You"ve said enough, Jan. Now leave us in peace. I"m not coming back with you-that"s final."

Storr turned on Penley. "You"re not letting her walk out of here just like that! Once she gets back there, she"ll have this place swarming with security!" Desperate for a weapon, Storr s.n.a.t.c.hed up a knife-but Penley"s voice brought him to a halt.

"Storr-no!" The gun was pointing at Story now. He dropped the knife back on to the table.

"It"s the only way!"

"It"s not my way-or yours." replied Penley calmly, then switched his gaze to Jan. "She won"t give us away. I"m sure of that."

"I give you my word..." Jan said quietly.

Storr turned array, disgusted by Penley"s weakness. "I don"t trust any of them," snarled the burly hunter, "whatever they say!"
