‘Stop!’ yelled Steven.
THIRTY-EIGHT
‘Don’t touch the door,’ said Steven. ‘You said the room was under constant negative pressure but listen… the ventilation system isn’t running at all.’
‘We turn it off at the weekend,’ said Lukas, and then had immediate second thoughts. ‘But on the other hand, it should have started up automatically when someone came in here…’
Steven, who had been wandering round the lab, inspecting the benches, held up two glass petri dishes, one in either hand, and asked Lukas what they were.
Lukas looked puzzled as he walked over to join Steven. ‘We don’t leave cultures of micro-organisms lying around ever,’ he said. He took one from Steven and examined it closely. ‘It’s like some kind of fungus,’ he said. ‘I don’t understand it. This has nothing to do with us.’ He looked at the other paraphernalia on the bench, more petri dishes, racks of test tubes, flasks. ‘We haven’t been working on anything like this. I’ve no idea how any of this got here…’
‘I have,’ said Steven. ‘Monk’s been setting the scene for one of his “accidents”.’
Macmillan, who had now joined the other two at the bench, surveyed the scene and could take little comfort from the look on Steven’s face. ‘Go on,’ he said.
‘I don’t think this is just any fungal culture,’ said Steven. ‘It’s the organism they used on John Motram. The cultures have been left here to make it look as if we were investigating the organism when we had our accident. At least, that’s what the authorities are supposed to think when they find us with our brains turned to mush.’
‘But how?’ asked Macmillan. ‘We’re not going to contaminate ourselves with these.’ He eyed the cultures on the bench. ‘Are we?’
‘No,’ said Steven thoughtfully. ‘They’re window dressing. We were supposed to come round, thank our lucky stars we were still alive and then walk out of here… and that’s when it’ll happen.’
The other two followed him over to the airlock exit where he stopped and turned round to look up at the ceiling, in particular the rectangular wire grating above them.
‘That’s for the positive pressure airflow into the room,’ said Lukas, following Steven’s line of sight. ‘Air leaving the lab has to go through the filter system over there, maintaining a pressure differential.’ He pointed to a series of extractor units on the other side of the room.
‘It’s my bet the system’s been loaded with toxic spores of this organism,’ said Steven. ‘As soon we trigger the door release, the fans will spring into life, flooding the room with fungal spores instead of the fresh air they’re supposed to pump in. Monk will have jammed the door on the other side of the airlock so we can’t get out.’
‘So we’re trapped,’ said Macmillan, reaching a conclusion no one felt inclined to argue with.
‘Unless we can come up with a way of getting out of here without triggering the ventilation system,’ said Steven, looking at Lukas, who shook his head.
‘There are half a dozen safety systems in place to make sure that it does turn on whenever it looks as if the lab is going to be open to the outside world,’ he said. ‘There’s even an auxilliary back-up if mains electricity should fail.’
‘Shit.’
‘What happens if we just sit tight and wait?’ asked Macmillan. ‘I mean, I know it could be a long weekend for us, but when one of Lukas’s people arrives on Monday morning…’
‘They’d trigger the fans; we’d be dead by the time they figured out how to open the door and it would still look like an accident. Besides, Monk isn’t going to let that happen. He’s going to come back to check on things and unjam the door mechanism so his “accident” looks perfect.’
‘If you’re right about all this and we should breathe in these spores, how long have we got?’ asked Lukas.
‘Depends how long it takes us to kill each other,’ said Steven, to the horrified looks of the other two. ‘I’ve thought a lot about what happened to John Motram. I’m sure the Public Health and hospital people up in Scotland identified the fungus correctly, but they weren’t to know that it had been genetically modified. John Motram’s symptoms had Porton Down written all over them… the madness, the aggression. This bug’, he held up one of the dishes, ‘has been designed as a bio-weapon. The clever thing to do these days is not to design weapons that kill but to come up with ones that will cause maximum disruption and create a huge drain on your enemies’ resources. Something that drives your victim mad and turns him into a homicidal maniac, intent on killing his comrades, would be seen as the perfect weapon. The fact that the victim doesn’t die himself but develops breathing problems and liver disease, demanding expensive and intensive medical care as well as restraint, would be seen as the icing on the cake.’
Macmillan shook his head. ‘How would Monk get his hands on something like that?’
Steven shrugged. ‘The old pals act again?’ he suggested. ‘A friend of a friend at Porton thought they might like to see how their latest project worked in practice? The tomb opening at Dryburgh would have been seen as the perfect scenario for a test run.’
Macmillan looked ashen and Steven knew why. Sir John was of the old school and, despite plenty of evidence to the contrary over the years, couldn’t bring himself to believe that the UK would involve itself in such things. He’d never quite embraced the concept that you had to be as bad as the bad guys in order to survive. ‘This is still all supposition,’ he said, without much conviction.
‘Then let’s hope I’m wrong.’
‘What d’you think Monk will do when he comes back and finds us still alive?’ asked Lukas.
‘Trigger the fans,’ said Steven.
‘Stupid question,’ Lukas conceded.
‘As I see it,’ said Macmillan, ‘we’ve no evidence that what Steven is suggesting is right but we can’t take the risk of putting it to the test. We have to find a way of getting out of here without triggering the ventilation system.’
‘Easier said than done,’ said Steven, who was becoming edgy. He was very conscious of the fact that time was ticking by and Monk would be coming back.
‘Surely we could afford to trigger the system as long as we could get out quickly enough afterwards?’
‘We’d have to hold our breath for as long as it took.’
‘What I was thinking of was an explosion,’ said Macmillan. ‘If we could blow a hole in the wall, we could escape to the outside. Do you have the wherewithal to do that, Lukas?’
Lukas looked doubtful. ‘It’s a biology lab, Sir John,’ he said. ‘We don’t have much call for things that go bang…’ He looked to the glass-fronted chemical cupboards without much conviction.
‘What’s in the red cylinder?’
‘Hydrogen. We use it for creating anaerobic conditions for bacteria that don’t like oxygen.’
‘I seem to remember you can get a pretty fair bang with hydrogen gas, can’t you?’
‘You certainly can,’ interrupted Steven, who was losing patience. ‘There’s no doubt we have the ability to blow ourselves to kingdom come, which might be quicker than the fungal route, but as for blowing a hole in the wall, forget it. Unless Lukas can come up with something like nitro-glycerine — or anything else that we could create a controlled, localised explosion with — we can forget the big bang theory.’
‘Sorry,’ said Lukas. ‘No can do.’
‘So where do we go from here?’ said Macmillan.
Steven looked at his watch. ‘We came round about twenty minutes ago. Monk would expect us to have walked into the trap and be fighting each other to the death by now. He’ll probably be back here some time within the next hour to… tidy up loose ends.’
‘Christ,’ said Lukas. Macmillan said nothing.
‘As I see it, there’s no possibility of disabling the ventilation system for the reasons Lukas gave earlier — too many safety mechanisms — so that just leaves one option. We’ve got to remove the spores from the system. Monk and his pals couldn’t have had that much time to set this up so it’s my guess it will be something fairly simple inserted in the trunking above us. I’ve got to get up there to see if I can find it. What d’you think, Lukas? Is there room?’
