Part 18 (1/2)

'Are they wet?' whispered Li.

'They're waterproof,' hissed Alex. 'They'll light no matter what. You've seen them.'

Paulo looked up again. Li suddenly felt faint. A cough welled up in her throat and she pressed her mouth together in a tight line. If she coughed it would give their position away.

Alex was on his fourth match. The same thing happened. What was going on? He looked at the dead match in his hand, puzzled. Overhead the jets screamed. The noise seemed to throb in his head and he let it fall forwards against the drainpipe.

Paulo didn't feel too good either. His foot touched a dead vole and he felt sick. He tilted his head back to take a breath of fresh air from the crevice.

Fresh air... He suddenly realized. There must be a backdraught, was.h.i.+ng the fumes from the generator back down into the cave. That was why the matches wouldn't light. The cave was filling with carbon monoxide and putting them out. That's why there were all these dead creatures. It was like being locked in a small garage with the car engine running. If they didn't get out, they would asphyxiate too.

Alex suddenly found himself snapping awake, as though he had been about to fall asleep. Paulo was shaking him and pointing up the pa.s.sageway.

Alex was confused but his training took over. If Paulo thought something was dangerous enough to abort a mission, he didn't argue. He crawled.

Li was slumped against the wall, her head moving slowly from side to side. Paulo threaded his arm under her shoulders. She lay across him as though she was drowning. With the other arm, he pulled himself along after Alex.

Hex stared at the man as the sixth bullet emptied into the blue drum near his feet. The bald man didn't say a word, just concentrated on shooting. A professional.

Finished, he slammed the door. Hex heard the lock click.

The room became dark, except for a small window above the door. Too small to escape through, it was more like a large gla.s.s letterbox than a window.

The drums started to leak. The fumes caught his throat; it squeezed tight and he coughed violently. Through watering eyes he tried to read the label: PMK PMK. He didn't know what that was, but it had a big orange label with a cross on it, and underneath the word 'HARMFUL'. He coughed again. Other labels came into focus. METHYLAMINE METHYLAMINE. That accounted for the smell amines, if chemistry lessons were to be believed, smelled sharp and fishy. Next to methylamine was a row of orange labels. HIGHLY FLAMMABLE. HARMFUL. CORROSIVE. A box at the back labelled KETAMINE KETAMINE.

He tried to climb up on the drums but they slithered down in a slippery avalanche. Hex stepped out of the way and looked around the walls. Was there an air brick, a ventilation hole of some sort? No, nothing. He coughed again and kicked a drum out of the way. Why were there so many? If you needed that much chemical, wouldn't a big one be easier?

Give his brain a problem, he would try to solve it. There were a lot of small drums because you could hide them in a deer carca.s.s. Just like he'd seen the previous night when he and Li were watching the gamekeepers. That way you could take raw materials up to the factory on the moor without being seen.

For a moment Hex felt quite proud of himself for the deduction. Then a spasm seized his throat. It was more than coughing; it was retching.

There must be a way out but the walls were smooth and solid. Only one way in and out. One tiny window and no way to break it. The perfect place to keep a stack of illicit chemicals and the perfect place to keep an inconvenient guest out of sight. No difficult bullet holes for a coroner to query. They could just leave him in here with this noxious stuff until he was done, then remove him to some desolate spot and no one would know what had happened. He could disappear as efficiently as they undoubtedly would.

His eyes were streaming. The foul-smelling liquid was forming pools on the bare concrete floor; soaking into the cardboard ketamine box. Tears were streaming down his face. His nose and throat were raw. He kept retching in dry heaves.

Hex had really thought he was going to die when the man got out the gun. When the bullets went into the blue drums of chemicals, he had actually felt relieved. Now that seemed rather naive. Perhaps it might have been better if they had just shot him.

27.

LAST C CHANCE.

Alex crawled fast. Above, the sound of the helicopter and the fighter planes dwindled away. Were they leaving? Or was it just that he couldn't hear them any more? Was that also their hopes of flus.h.i.+ng these guys out?

They crawled past the end of the exhaust pipe. Behind him, Li had revived. Paulo brought up the rear, pus.h.i.+ng them on.

When they reached the end of the tunnel, Paulo stopped and they all gulped in fresh air. For a minute they all lay there, gasping.

Alex looked back the way they had come. 'We've got to get back. The police are waiting.'

Paulo pulled him back. 'Hombre, we can't. We'll die. And you'll never get the rope lit because there's no oxygen for it to burn.'

Li looked rather sick. She pushed some rocks out of the way and sat with her back against the tunnel wall. Paulo checked her pulse. 'I'm still alive,' she muttered, but she sounded faint. Perhaps because she was the smallest she had been worst affected.

Paulo moved away and winced as he bent his finger back on one of the pieces of rock she had moved. As he sucked the wound he had an idea. 'Pick up some of these,' he said, and grabbed a couple of small rocks.

Alex watched him crawl at top speed back down the tunnel, one-handed. He scooped up some rocks and followed.

Paulo had stopped at the end of the pipe. The smell of diesel fumes made Alex feel sick. Paulo was stuffing the pieces of rock into the end of the pipe. Alex pa.s.sed him his. They fitted in nicely.

After a few seconds Alex could have sworn the tang of diesel fumes was less strong. Paulo sat back on his haunches and grinned. 'In about sixty seconds they will smell fumes in there and the generator will stop. At that point the rats will come swarming out of their lair.'

They hurried back to Li. She was still taking deep breaths but was looking more alert.

Paulo ran his torch over her. 'How do you feel?'

'A bit sick,' Li said. 'I'll be fine.'

She got to her feet and staggered a little. Alex put out his arm and she took it. He realized he could still hear the planes.

Paulo took Li's other arm. 'Come on, let's go and see the show.'

The tunnel led upwards to a dusky sky. With every step they took towards the light the air became cooler and fresher. The sound of the planes and the helicopter became louder. The last part sloped up steeply.

Cautiously, the three members of Alpha Force emerged.

Up on the hill, the trapdoor was open, its light s.h.i.+ning into the sky. A helicopter skimmed ten metres off the ground, a triangle of light trailing from it like a skirt. Figures were running around on the moor. The skirt of light touched them, then lost them, then found them again. A shot was fired. Another helicopter circled in the sky, its spotlight brus.h.i.+ng over a number of bulky figures, crouched over sniper rifles around the moor. Armed police.

If the police hadn't believed them before, they certainly did now.

The gamekeepers were heading down the hill towards them. A pistol cracked. The submachine guns answered. Further off in the darkness Li saw a hooded shape, piercings twinkling, moving away in the darkness.

'Ivanovich,' she hissed. A wave of giddiness pa.s.sed over her and she lay back against the opening of the cave.

Paulo saw the drug dealer. A bulky figure was moving about ten metres away in the heather a police marksman. But he was facing the wrong way. He hadn't seen Ivanovich.

They couldn't shout for his attention. They'd never be heard in all the confusion.

Paulo squirmed forwards on his belly and tapped the rifleman on the shoulder. A head snapped round. Eyes looked at him from behind a balaclava. Paulo pointed at Ivanovich, half running, half crawling down the steep hill. The sniper fired, and the night lit up with starbursts of muzzle flash as other hidden gunmen followed his lead, the sound swallowed by the beat of the helicopter.

The heli pa.s.sed overhead, its spotlight swinging and illuminating Paulo. He was on an open patch of ground. Alerting the sniper had stopped Ivanovich getting away, but it had put him right in the line of fire.

He needed to get back under cover. He began to crawl, elbows digging into the earth.

The spotlight swung away. Alex saw that the gamekeepers were facing a line of armed police, bulked out by body armour. They raised their hands in surrender. Paulo was crawling towards him, his eyes glinting with determination.
