Schofield spun in the water； looked about himself； then snapped up to look at the lens…like surface again。
And at that moment； the lens shattered。
Elephant seals plunged into the water from every side。 Others roared out of the submerged holes in the walls and charged at Schofield and the others。 Their shrieks and barks and whistles filled the water。
Kirsty and Renshaw broke the surface first； right near the edge of the pool。 Renshaw…still in the water…pushed hard against the underside of Kirsty's tanks； forcing her out of the water。
Kirsty stumbled frantically up onto dry land； slipped and fell； flat onto her face； and turned just in time to see Renshaw get one arm out of the water and begin to haul himself out when…yank…Renshaw was suddenly wrenched violently under the churning surface。
Kirsty screamed but cut herself off when she saw an enormous shape rise up out of the water in front of her。
She dived away from the water's edge just as one of the elephant seals launched itself out of the water and crashed down onto the ice in front of her。 Kirsty staggered and stumbled away from the edge； turned； and saw that the giant seal was loping across the flat floor of the cavern； chasing her！
Kirsty clawed at the icy ground； lost her footing； slipped； and fell。
The elephant seal charged。 Kirsty lay sprawled on the floor of the cavern； totally exposed； staring up at the gigantic demon bearing on her and…
And then suddenly boom！ the elephant seal's face exploded in a fountain of blood and the big seal went crashing headfirst to the ground。
Kirsty stared in awe as the elephant seal dropped to the floor； revealing behind it： Schofield； hovering in the pool thirty feet away； with his pistol extended。
He had just shot the seal through the back of the head！
Kirsty almost fainted。
Under the surface； James Renshaw was absolutely panic…stricken。
One of the seals had pulled him under and now it had him； had his foot in its mouth！
Renshaw looked down in desperation； and then suddenly he frowned。 The seal that had him looked smaller than the others； and it had those distinctive lower fangs that he had seen on the larger male before。
A juvenile male？ Renshaw thought。
And then another thought hit him。
If it's young； you might have a chance to get out of this。
So； with his spare foot； Renshaw kicked the small seal hard in the snout。
The seal instantly squealed with pain and released his foot； and Renshaw bolted for the surface。
He burst up out of the water a second later and saw the edge of the pool right in front of him。 Then he grabbed the nearest rock and hauled himself out of the water just as another； much larger seal； probably the juvenile's mother； swept through the water behind him and narrowly missed biting his feet clean off。
Schofield was swimming madly for the edge of the pool。
As he swam； he caught fleeting glimpses of the cave around him…he saw Kirsty over on one side of the pool； saw Renshaw over on the other。 And then he saw the the ship； the big black ship； standing like an enormous； silent bird of prey in the middle of the massive subterranean cavern。
And then suddenly his view of the big black ship was obliterated by the sight of the big bull seal rising up out of the water right in front of him！
The big seal was already moving fast and it plowed into Schofield at phenomenal speed and Schofield gasped as he felt the wind get knocked out of him and he went under。
The bull seal had rammed into his chest with its long lower fangs。 Ordinarily； Schofield guessed； this would have been enough to kill any would…be victim； since the big seal's fangs would pierce the victim's chest
But not with Schofield。
He was still wearing his body armor； and the bull seal's fangs had lodged in his Kevlar breastplate。
The elephant seal drove him downward； pushing against his chest。 Schofield struggled； but it was no use。 By virtue of his breastplate he was practically impaled on the big animal's fangs。
The seal took Schofield down。 Down and down； on the end of its nose。 Bubbles shot out from its heaving mouth as it expelled vast quantities of air in its exertion。
Schofield had to do something。
He reached into his pocket； searched for whatever lay in there。
He pulled out a British nitrogen charge； looked at it for a second。
Oh； what the hell； he thought
Schofield quickly pulled the pin on the nitrogen charge and ammed the live grenade into the open jaws of the big elephant seal。
Then he pushed himself off the big animal's fangs and the seal shot past him in the water。 It quickly realized that it had lost Schofield； and when it did； the big seal began to turn around。
It was then that the nitrogen charge went off。
The bull seal's head exploded。 Then it imploded。 And then most shocking thing of all happened。 A wave of ice shot out from the dead seal's body。 At first Schofield didn't know what it was； and then suddenly he realized。
It was the liquid nitrogen from the charge； expanding through the water； freezing the water as it went！ Shit。 He hadn't counted on that！ The wall of ice shot through the water toward Schofield； constantly expanding； like a living； breathing ice formation growing through the water。
Schofield watched it with wide eyes。 If it enveloped him； he would be dead in an instant。
Get out of here！
And then suddenly Schofield felt something nudge against his shoulder and he turned。
It was Wendy！
Schofield grabbed her harness and Wendy took off immediately。
The wall of ice behind them gave chase； expanding through the water at phenomenal speed； building upon itself at an exponential rate。
Wendy swam hard； pulling Schofield with her。 She was small； but she hauled Schofield through the water at incredible speed。
The ice wall closed in on them。
Another elephant seal swung in behind them； spying an easy meal； but the ice wall caught the big seal； enveloped it within its expanding mass； and swallowed it whole； froze it within its icy belly。
Wendy swam； toward the surface； deftly avoiding any elephant seals that tried to cut across her path。
She saw the surface； pulled Schofield toward it。
Behind them； the wall of ice had lost its momentum。 The nitrogen from the charge had ceased expanding。 The ice wall fell away behind them。
With Schofield clutching onto her harness； Wendy made her run for the surface。 Elephant seals came at them from every side。 It was like a roller…coaster ride as Wendy ducked and weaved and banked and turned to avoid the biting teeth of the elephant seals charging at her and Schofield from every side。
And then suddenly Wendy spotted a gap and caught a glimpse of the surface。
She went for it。
Elephant seals lunged and snapped at them from every side； but Wendy was too quick。 She hit the surface at full speed and exploded out of the water。
Wendy shot out from the water； with Schofield holding onto her harness。 They both hit the icy floor of the cavern with a clumsy thud； and Schofield found himself lying on his belly。 He quickly rolled over onto his back…
…only to see an elephant seal leap high out of the water behind him and e rushing down toward him！
Schofield rolled。 The elephant seal slammed down onto the ground right next to him。 Schofield leaped to his feet； spun around； looked for the others。
〃Lieutenant！ Over here！ Over here！〃 Sarah Hensleigh's voice yelled。
Schofield snapped around and saw Hensleigh waving from inside a small horizontal hole in the wall about fifty yards away。
Renshaw； Kirsty…and Wendy； too…were already moving toward the horizontal fissure。 Schofield took off after them。 As he ran across the cavern； he saw Kirsty roll in through the horizontal hole； then he saw Wendy go in after her； then Renshaw。
Suddenly a wash of static cut across his consciousness and a voice yelled loudly in his ear。
〃…you out there？ Scarecrow； are you out there？ Please respond！〃 It was Romeo。
〃What is it； Romeo？〃
〃Jesus！ Where have you been？ I've been trying to get you for the last ten minutes。〃
〃I've been busy。 What is it？〃
〃Get out of the station。 Get out of
