Schofield jammed his pistol back into its holster and looked down at Kirsty。 He saw the tears in her eyes。
As he looked down at her； Schofield realized that he was still wearing his silver antiflash glasses。 He took the silver glasses off and crouched down in front of Kirsty。
〃Hey；〃 he said。 〃It's OK。 It's all right。 I'm not going to die on you。I am not going to die on you。〃 Schofield smiled。 〃I mean； hey； I can't die。 I'm the hero of this story。〃
Despite herself； Kirsty smiled。 Schofield smiled； too。
And then； to his surprise； Kirsty stepped forward and hugged him。 Schofield returned her hug。
As he held her； though； he heard a strange noise。 A noise that he had not heard before。
It was a loud； rhythmic； crashing noise。
Boom。
Boom。
Boom。
It sounded to Schofield like…
Like waves crashing on a beach。
With a sickening rush； Schofield realized where they were。 They were near the cliffs。 Their evasive maneuvers during the hovercraft chase had taken them out near the sheer three…hundred…foot cliffs that towered over the bay。 The loud； booming noise that he was hearing was the sound of the mountainous waves of the ocean smashing against the ice cliffs。
He was still holding Kirsty in his arms。 As he held her； though； something behind her caught his eye。
Attached to the side of the British hovercraft's dashboard was a small partment； mounted on the wall。 Its door hung ajar。 Inside the partment； Schofield could see two silver canisters。 They were each about a foot long； and cylindrical in shape。 Each silver canister had a wide green band painted across its midsection。 Schofield saw some lettering stencilled onto the side of one of the silver canisters： TRITONAL 80/20。
Tritonal 80/20？ he thought。 Why on earth would the British bring that to Wilkes？
Tritonal 80/20 was a highly concentrated explosive poxy… a highly bustible liquid filler that was used in air…launched drop bombs。 Tritonal wasn't nuclear； but when it blew； it blew big and it blew hot。 One kilogram of the stuff… the amount contained in each of the canisters Schofield was now looking at…could level a small building。
Schofield released Kirsty gently； put his glasses back on； and moved toward the partment near the dashboard。 He pulled one of the silver…and…green canisters from it。
He came back to Kirsty。 〃Are you all right； now？〃
〃Yeah；〃 she said。
〃Good；〃 Schofield said； sliding the Tritonal charge into one of his long thigh pockets。 〃Because I really have to get back to…〃
Schofield never saw it ing。
The impact threw him off his feet。
His whole hovercraft lurched suddenly to the left。
He looked out through the gaping hole in the right…hand side of his speeding hovercraft and saw one of the two remaining British hovercrafts racing across the ice plain right alongside him！
It rammed them again。
Hard。
So hard； in fact； that Schofield felt his hovercraft slide sideways； to the left。
〃What the…〃 he said aloud。
He looked left and in a sudden terrifying instant he realised what they were doing。
〃Oh； no；〃 he said。 〃Oh； no。。。。〃
They were trying to ram him off the cliff。
Schofield began to wrestle with the steering vane of his hovercraft； but it was no use。
There was nowhere he could go。
With no room to move…no room to get a run…up…he just found himself shunting the speeding British hovercraft ineffectually。
The British hovercraft rammed them again； and Schofield snapped to look forward。 He saw the cliff edge racing by less than ten yards off to his left。 He caught a glimpse of tiny white…crested waves beyond it。 They were a long way down。
Then he looked out to his right； out through the hole in the side of his speeding hovercraft； and saw the black British hovercraft whipping across the ice plain beside him。 He saw it widen the gap between the two hovercrafts and then suddenly rush back in at them。
The two hovercrafts collided again and Schofield felt his hovercraft jolt farther toward the edge。
Five yards to go。
The two hovercrafts raced along the edge of the cliff top； three hundred feet above the churning white waves of the Southern Ocean。
Schofield was still watching the British hovercraft alongside him。
As it widened the gap between the two hovercrafts once more…like a boxer pulling his arm back in preparation for the next blow…suddenly Schofield saw another hovercraft materialize in the distance beyond the black British hovercraft。
He blinked。
It was the orange French hovercraft。
The orange hovercraft？ Schofield thought。
But the only person in that hovercraft was 。。。
Renshaw。
Schofield saw the gaudy orange hovercraft pull alongside the speeding British hovercraft。 Now there were three hovercrafts travelling side by side along the edge of the ice cliff！
Suddenly the British hovercraft rammed them again and ihe skirt of Schofield's hovercraft jutted out over the edge of the cliff。 Large chunks of snow were thrown off the edge。 They became tiny specks of white as they disappeared into the churning foam of the sea three hundred feet below。
〃e on。〃 Schofield suddenly grabbed Kirsty's hand。
〃What are we…〃
〃We're leaving；〃 he said。
Schofield pulled Kirsty over to the gaping hole in the right…hand side of his hovercraft。
He saw the British hovercraft pull away from them again； preparing itself for the killing blow。
Schofield swallowed。 He would have to time this just right。。。。
He drew his Desert Eagle pistol。
The British hovercraft rushed in toward them。
The two hovercrafts collided； and in that instant Schofield leaped across onto the skirt of the British hovercraft； pulling Kirsty with him。
They landed on the skirt of the speeding British hovercraft just as their own went careering off the edge of the cliff。 The empty hovercraft rolled through the air for an instant before it plummeted three hundred feet straight down。 It hit the water with a stunning impact and smashed into a thousand pieces。
Schofield and Kirsty never stopped moving。
They skipped across the roof of the British hovercraft； and as they did so Schofield pointed his pistol straight down and fired three quick shots into the roof beneath him； and then suddenly they were on the other side of the hovercraft and Schofield could see Renshaw's hovercraft in front of them。
The orange hovercraft swung in closer just as Schofield and Kirsty leaped off the skirt of the British hovercraft。 They landed safely on the skirt of Renshaw's craft； and it instantly peeled away from the black British hovercraft。
Schofield looked back at the British hovercraft…saw a star of blood on the forward windshield。 Someone inside the hovercraft was still moving； clambering forward in an attempt to grab the steering vane。
Schofield figured that he must have hit the driver and now whoever was still in there was desperately trying to regain control of the…
Too late。
The British hovercraft looked like a stunt car leaping off a ramp as it shot off the edge of the cliff。 It sailed through the air for a moment…soaring high…before gravity took its course and the hovercraft began to arc downward。 Schofield caught a fleeting glimpse of the man inside it as the hovercraft dropped below the edge of the cliff top and disappeared forever。
Schofield turned to see the sliding side door of the orange hovercraft open in front of him and he saw Renshaw's smiling face appear。
〃Can I drive this thing or what？〃 Renshaw said。
Now there was only one British hovercraft remaining。 Outnumbered now by two…to…one it kept its distance。
Schofield grabbed Renshaw's Marine helmet and put it on。 He keyed the helmet mike。 〃Rebound； you still out there？
〃Yeah。〃
〃Is everyone OK？〃
〃More or less。〃
〃What about the hovercraft？〃 Schofield asked。
〃She's a bit beat up； but she's OK。 We've got full power again；〃 Rebound's voice said。
〃Good；〃 Schofield said。 〃Good。 Listen； if we take care of this last guy； do you think you can get a head start and make it to McMurdo？〃
〃We'll get there。〃
〃All right； then；〃 Schofield said as he looked down at Kirsty。 〃Stand by。 You're about to get another
