as the channel that had brought him here, there were several others; the widest, stone at its bottom rather than ice, was carrying the flowing water away. Most of the others were feeding it, streams running from them into the pool.
One, though, had dried up, crystalline sparkles along its floor. As far as he could tell, it headed back in the general direction of the collapsed bridge - and Sophia.
He sloshed out of the pool and hurried into the frozen channel.
One of Hammerstein’s men ran back to him. ‘No good, sir - I lost sight of him.’
Hammerstein glowered at the wrecked bridge. He had seen Sophia Blackwood trying to jump from it as it fell - but she had landed on the far side of the rubble, out of sight. For the moment, she was unreachable.
But not for long. ‘Follow me,’ he said, climbing over the wall and dropping on to the ice below, then climbing down into the nearest channel. ‘We’re going after them.’
Despite the cold, Chase was sweating, steam filling the darkened ice channel. The large building was, he guessed, where the volcanic vent emerged; the Veteres had presumably used it to supply this part of their city with hot water, an ancient form of central heating. Nina would be fascinated, he knew, but his concerns were more prosaic.
Foremost on his mind:
The channel twisted and coiled, others splitting off it to form a confusing labyrinth. Unable to get his bearings from the cavern’s ceiling, he was no longer sure if he was heading in the right direction to find Sophia - or even if the passage he was following joined up with hers. He had tried to climb out, but again the smooth, slippery walls defeated him.
He moved on. In places the walls between channels were thin enough to become almost transparent; in others, they were more like mirrors, his reflection rippling confusingly around him. The beam from his gun’s light bounced off the glittering walls, making it seem as though there were dozens of men prowling through the ice around him . . .
He stopped, statue-still.
One of the lights was still moving.
Chase flicked off the spotlight. The passage plunged into near darkness, the all-pervading blue of the cavern coming faintly through the surrounding ice. The moving light paused, casting faint echoes of itself all around.
Chase took his best guess of the gunman’s true position, then crept into the gloom.
The trooper looked cautiously round. He was sure he had seen a light - which had then disappeared - but the distortion of the surrounding ice walls made it hard for him to be sure of its exact location. Gun raised, he lifted his radio. ‘This is Reiss,’ he whispered. ‘I’m in the eastern part of the covered section - are either of you near me?’
Hammerstein responded quietly. ‘No - I’m at the south end, and Munk is north of me.’
‘I just saw a light go out - he’s here, close by.’
‘We’ll come to you. Be careful. Out.’
Reiss clipped the radio back to his belt, then moved step by step along the passage, his gun’s spotlight illuminating the way. Steam curled past as he rounded a corner and entered an intersection, other channels twisting away in different directions.
He advanced, pointing the light down each passage in turn. Movement in one - he snapped the gun to it, before realising it was just the glint of his own beam. Tensing, he continued his sweep, moving onwards to check a second channel, a third . . .
A shadowy figure behind a translucent wall—
Reiss fired - and the thin wall burst apart, shattered chunks cascading everywhere to reveal . . .
Nothing.
He aimed his spotlight at the ragged hole, seeing another shiny wall of ice beyond it. His radio crackled. ‘Reiss!’ called Hammerstein. ‘Did you get him?’
Reiss unclipped the radio. ‘No, it was just a reflec—’
Chase stepped up behind him and snapped his neck with a brutal crack.
The soldier collapsed, head lolling horribly. ‘Ice to see you,’ said Chase in an Arnold Schwarzenegger voice, immediately wishing he’d thought of something better. He took the magazine from the dying man’s TAR-21, then continued deeper into the maze.
‘Reiss!’ Hammerstein shouted. ‘Reiss, answer!’
No reply. But the abruptness with which he had been cut off told Hammerstein his subordinate was dead. ‘Man down,’ he warned his remaining team member. ‘Munk, watch yourself. These tunnels are like a damn hall of mirrors - don’t fire unless you’re sure it’s him.’
‘Roger,’ replied Munk. He had increased his pace through the maze on hearing gunfire, but the sudden termination of Reiss’s message brought him to a sudden stop. The echoes made it hard to judge, but the loudness of the shots suggested they had been no more than twenty metres away, to the east.
The channel he was traversing curved in that direction. He peered round the corner. No sign of anyone. He rounded the bend and moved warily along the frozen passage, his distorted reflections slithering along the glassy walls alongside him. The gun’s spotlight beam flickered back at him, diamond-glints trapped within the ice. He stopped, listening.
A faint crunching. Boots on ice. Close by.
It couldn’t be Hammerstein; the noise was coming from the wrong direction. And there was no sign of another spotlight.
Chase.
Munk brought his gun up to his shoulder, the scope’s glowing dot a floating holographic point. Ahead, the channel he was in criss-crossed another. Another muffled crump, another step by his quarry. Getting closer . . .
He switched off the light, not wanting to give Chase any advantage. Reflections became sinister twisted shadows as he slowly advanced. He reached the intersection and looked round the first corner.
Movement. His heart thumped. A figure was creeping along the passage. But it rippled as it moved, merely a reflection. The channel twisted sharply; Chase was round the corner . . .
Munk stepped out, taking aim at where he would emerge, the red dot hovering at head height as the reflection turned—
Shots tore
Hammerstein heard the shots. Not far away. But had it been Munk firing, or . . .
‘Munk,’ he said into the radio. ‘Munk, respond.’ Silence. ‘Munk!’
It had been Chase. Hammerstein spat a Hebrew curse and reloaded the grenade launcher. If it took overkill to bring him down, so be it.
28
Two down, one to go, but even with the improved odds Chase didn’t feel like celebrating. The man he had just killed wasn’t the leader, Hammerstein - which meant he still had to face the most dangerous member of the unit.
He moved on through the ice tunnels. The steam grew steadily thicker; the icy walls started to drip, water
