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 
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.
But the only person in that hovercraft was ...
 Schofield saw the gaudy orange hovercraft pull alongside the speeding British hovercraft. Now there were 
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.
'Come 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 
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?
'Is everyone OK?'
'What about the hovercraft?' Schofield asked.
'
'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?'
'All right, then,' Schofield said as he looked down at Kirsty. 'Stand by. You're about to get another passenger.'
Schofield got Renshaw to pull his hovercraft alongside Rebound's transport. He wanted to put Kirsty on the transport and then send it on its way to McMurdo while he and Renshaw took care of the last British hovercraft.
The two speeding hovercrafts came together.
Both side doors slid open.
Book appeared in the side door of Rebound's transport raft. Schofield stood with Kirsty in the door of the orange French hovercraft opposite him.
The last British hovercraft hovered ominously behind them, two hundred yards astern.
'
Schofield said to Kirsty, 'You ready?'
'Uh-huh,' she said.
They stepped out onto the skirt together.
In the cabin of the transport craft, Rebound was keeping a wary eye on the British hovercraft.
It just seemed to sit there, watching them.
'What are you doing, you son of a bitch?' Rebound said aloud.
Book yelled, '
Schofield and Kirsty edged forward, toward the edge of their hovercraft's skirt The wind buffeted them relentlessly.
