'So what are they going to do?'
'No one knows. But I've got a feeling they'll find a way.' He sighed again, and Bolt could see the pressure his boss was under. 'If they somehow get it out into the atmosphere, it'll be a bloody catastrophe. It's a sunny day with a light breeze, which is meant to be perfect conditions for releasing it. I don't mind telling you, I'm glad my missus isn't up in town today.'
Bolt was surprised at his honesty. Big Barry Freud usually towed the party line, but these, it seemed, were unprecedented times. 'Plenty of peoples' wives are,' he said, thinking about Mo and Saira, and their four children. He'd dropped Mo back at home on the way here earlier so he could grab a bit of sleep and they could spend some time together, and he wondered whether he'd sent them out of town as well.
'If the powers-that-be think there's a need to evacuate, then they'll do it,' said Big Barry, 'but they're setting up roadblocks coming into town and the congestion charge cameras are tracking any white lorries.' He was trying to sound confident but it wasn't really working, and he was saved from further conversation by the ringing of his phone.
It was clear the caller was from the ANPR. Barry wrote something down on the giant notepad that covered half his desk before hanging up.
'The Mazda was last caught on the ANPR yesterday afternoon at 2.47 p.m. just north of Saffron Walden in Essex on the B1052 at Linton in Cambridgeshire. If it's been used since, then it hasn't gone far because it would have been caught on one of the other cameras. They're going to send us a map showing the area where it might still be.'
Bolt smiled. 'That should narrow it down a bit.'
But when the map was emailed through to Barry's PC ten minutes later, it was clear that it hadn't narrowed things down as much as either of them would have liked. Although the Mazda's last location was surrounded by cameras, it was a largely semi-rural area of northern Essex, with hundreds of back roads and villages, bordered by the M11 to the west, and the computer-generated map calculated that the car could be anywhere in an area of almost 190 square miles.
'Christ, that doesn't help us much, does it?' said Big Barry as they pored over the printout. 'I've got a tag on those plates, so if the car starts moving again we'll know as soon as it's picked up by a camera. Until then, though…'
Bolt wasn't entirely deterred. 'You say the gas can't be released very easily manually, right? So, if they're going to come up with a way of releasing it effectively, they're going to have to take it somewhere to get it ready, don't you think?'
Big Barry shrugged. 'I don't know. It's possible, I suppose.'
'Well, maybe the car's gone to the same place. Hook hasn't got a big team. So far we only know of one person working with him.'
'I still don't see what you're getting at, Mike.'
'I'm thinking that maybe they've got a base round there somewhere. A centre for their operations.' He ran a finger in a wide circle on the map. 'A place they would have rented. If you can let me take a couple of people from my team off the CCTV trawl, we can look up all the estate agents in the area, see who's rented out property recently. It's a long shot…'
'An extremely long shot. We don't even know that the car hasn't just been abandoned in a wood somewhere.'
'But it's got to be worth a look. We've got two hundred people working on the CCTV. Surely we can spare a couple of them?'
Big Barry looked doubtful, but he was the sort of guy who always liked to cover all his bases, just in case there was an opportunity for personal advancement in one of them. 'OK, take one person.' He looked at his watch. 'It's eleven now. We'll review how you're getting on at two.'
Bolt thanked him and walked out with the map before his boss had a chance to change his mind. It was still a case of searching for a needle in a haystack, but at least the haystack was getting smaller.
And any effort was worth it if it led to Tina.
Fifty-two
The interior of the lorry's cab still reeked of death, even though they'd removed the driver's body more than an hour earlier, and Eamon Donald was pleased when he'd finished drilling the holes through to the back that were needed for the bomb's wires, and could finally get out into the comparative fresh air for a much-needed smoke. He'd been trying to give up for the best part of a decade now, a process that had started when his old man, a lifelong smoker, contracted terminal lung cancer, but he'd never managed to last for more than a week, and for the time being at least he'd given up giving up.
He lit a Marlboro Light and approached Stone and O'Toole, both of whom were hard at work among the pieces of drainpiping Stone had been sawing up earlier. O'Toole was using a large measuring jug to fill up each tube with a ready-made explosive slurry mix of ammonium nitrate and fuel oil that he was getting from a barrel next to him, while Stone was on his hands and knees attaching handfuls of six-inch nails to the tube exteriors using thick rolls of industrial masking tape. Every ingredient they were using could be bought legally by people who knew what they were doing.
'How's it going, lads?' Donald called out, making sure he stood well back from them with the cigarette.
'Another hour, I reckon,' answered O'Toole. 'Then we're going to need a break.'
Stone grunted something that sounded like agreement.
'And when you're done you can have one, don't worry.'
Donald looked at his watch. It had just turned half past twelve and they were well ahead of schedule. He was also beginning to get hungry, and hoped that Hook had got in some supplies. Donald liked his food, and he'd always found it difficult to function on an empty stomach. Somehow, though, he knew Hook wouldn't have anything tasty on offer. He wasn't the kind to get pleasure from eating. He wasn't really the type to get pleasure from anything bar, it seemed, rape and murder.
As he thought these unkind thoughts about his current employer, the barn doors opened and Hook appeared in his Friday the 13th-style boiler suit and gloves, his anaemic face looking like something out of a 'plastic surgery gone wrong' documentary. Donald wondered how the guy ever managed to blend into a crowd, as he was reputed to be able to do. To him, Hook blended in like a go-go dancer in a nunnery.
As Donald took a long, much-needed pull on the cigarette, Hook came over and guided him towards the front of the lorry, well away from Stone and O'Toole, and out of earshot.
'How's it coming along?' he asked.
'We're doing fine. Your bomb'll be ready on time.'
Hook nodded. 'Good. That's what I want to hear.' But there was something tense about him. He wrinkled his nose, glancing at the cigarette, and Donald remembered that he didn't like smoking.
Tough titty. He took another drag, savouring the taste.
They stopped at the cab, and Hook fixed him with a probing stare. 'I hear that when mustard gas ignites it loses its effect. How are you intending to fix that?'
'Ah, I see you've done your homework.'
'I always do my homework, Eamon.'
'Well, it's very simple really,' he said, unable to mask the enthusiasm he always felt when talking about bombs. 'When those two over there have finished filling the tubes with explosive mix, I'm going to put a detonator in each one and run them through the gaps in the pallets holding the gas. By my calculation there should be two tubes for each pallet. Then we wire them up to a connector box, which is basically the bridge between the explosive-filled tubes and the main detonator in the cab. When we set off the main detonator, the connector box will send a signal through the wiring and our thirty-two mini bombs will explode simultaneously, sending the nails attached to the outside of the tubing flying everywhere, and with enough force to puncture all the cylinders.
