Sheila shrugged. 'He seems pretty optimistic,' she said.
'If it does work, will it kill the person?' Pitt asked. He was thinking about Cassy and even Beau.
'There's no way to know,' Sheila said. 'For as much as we know, at this point we're stumbling around in the dark.'
'Hold up!' Vince said. He had the binoculars pressed against his eyes. 'I think I see some tracks leading off toward the south.'
'Where?' Beau asked.
Vince pointed.
Beau nodded. 'Take us down to the ground,' he told the pilot.
The pilot set the helicopter down on the tarmac. Still, a tremendous amount of sand and dust swirled up into the air.
'I hope all this dirt doesn't cover the tracks,' Vince said.
'We're far enough away,' the pilot said. He turned off the engine and the rotors came to a halt. Vince and the policeman sitting next to him, named Robert Sherman, immediately got out and jogged up the road to where the tracks were. Beau and the pilot climbed out of the cab as well, but they stayed next to the copter.
Beau was breathing heavily through his mouth with his tongue hanging out like a panting dog. The alien skin was not equipped with sweat glands, and he was beginning to overheat. He looked around for shade, but there was no escape from the merciless sun.
'I want to get back into the chopper,' Beau said.
'It'll be too hot in there,' the pilot said.
'I want you to start the engine,' Beau said.
'But that will make it difficult for the others to return,' the pilot said.
'The engine will be started!' Beau growled.
The pilot nodded and did as he was told. The air conditioning came on and quickly lowered the temperature.
Outside the slowly rotating blades kicked up a miniature sandstorm. They could barely see the two men a hundred yards ahead as they bent over to examine the ground.
The radio activated and the pilot slipped on his headset. Beau glanced off at the featureless horizon to the south. Along with his anger he was feeling progressively anxious. He hated these human emotions.
'It's a message from the institute,' the pilot told Beau.
'There's a problem. They cannot go to full power on the electrical grids. The system trips the circuit breakers.'
Beau's long snakelike fingers intertwined to form tight, knotlike fists. His pulse quickened. His head pounded.
'What should I tell them?' the pilot asked.
'Tell them I'll be back soon,' Beau said.
After signing off, the pilot removed his headphones. He was experiencing a trace of Beau's mental state via the collective consciousness, and he fidgeted in his seat. He was relieved when he saw the others returning.
Vince and Robert had to cover their faces against the stinging sand as they ducked under the rotating blades to climb into the copter. They didn't try to talk until the door was closed.
'It's the same tracks that were at the old gas station,' he said. 'They head south. What do you want to do?'
'Follow them!' Beau said.
With great difficulty Harlan, Sheila, Pitt, and Jonathan had managed to get six of the infected mice into a type III biological safety cabinet.
'It's a good thing they weren't rats,' Pitt said. 'If they had been any larger than mice, I don't think we could have handled them.'
Harlan was letting Sheila put disinfectant and bandages on several of the bites he'd gotten. 'I knew they were going to be trouble,' he said.
'What are we going to do now?' Jonathan asked. He'd become intrigued by the experiment.
'We're going to introduce the virus,' Harlan said. 'It's in that tissue culture flask that's already inside the hood.'
'Where does this cabinet vent?' Sheila asked. 'We don't want this virus getting out if it's not going to work.'
'The exhaust is irradiated,' Harlan said. 'No worry there.'
Harlan stuck his bandaged hands into the thick rubber gloves that penetrated the front of the cabinet. He grasped the tissue culture flask, pulled out the stopper, and poured the medium out in a flat dish. 'There,' he said. 'That will vaporize rapidly, and then our little furry friends will be breathing in the artificial virus.'
'What are the black dots on the back of each mouse?' Jonathan asked.
'Each dot represents how many days ago the mouse was infected,' Harlan said. 'I was infecting them sequentially so that I could follow the infestation process physiologically. Now I'm glad I did it. There might be a different reaction depending on how much the enabled virus had expressed itself.'
For a few minutes all four people stood in front of the cabinet and watched the mice race around the cage.
'Nothing is happening,' Jonathan complained.
'Nothing on the level of the entire organism,' Harlan said. 'But my intuition tells me a lot is happening on a molecular/cellular level.'
A few minutes later Jonathan yawned. 'Wow,' he said. 'This is like watching paint dry. I'm going back to the computer.'
A few minutes later Pitt broke the silence. 'What is interesting is how they are seemingly working together. Look how they are forming a pyramid to explore up the glass.'
Sheila grunted. She'd seen the phenomenon but wasn't interested. She wanted to see something physical happen to the mice. Since their level of activity hadn't changed, she was beginning to feel progressively nervous. If this experiment didn't work, they'd be back to square one.
As if reading Sheila's thoughts, Harlan said: 'We shouldn't have long to wait. My guess is that it will only take the induction of one cell to initiate a cascade. My only worry is that we didn't test the viability of the virus. Maybe we should do that.'
Harlan turned away to do what he'd suggested when Sheila grabbed his arm. 'Wait!' she cried. 'Look at that mouse with the three dots.'
Harlan followed Sheila's pointing finger. Pitt crowded in behind, looking over Harlan's shoulder. The mouse in question had suddenly stopped its incessant rapid wandering around the cage to sit back on its haunches and repeatedly wipe its eyes with its front paws. Then it jerked a few times.
The three observers exchanged glances.
'Are those mouse sneezes?' Sheila asked.
'Damned if I know,' Harlan said.
The mouse then swayed and toppled over.
'Is it dead?' Pitt asked.
'No,' Sheila said. 'It's still plainly breathing, but it doesn't look so good. Look at that foamlike stuff coming out of its eyes.'
'And mouth,' Harlan said. 'And there's another mouse starting to have symptoms. I think it is working!'
'They are all having symptoms,' Pitt said. 'Look at that one with the most dots. It looks like it is having a seizure.'
Hearing the commotion Jonathan returned and managed to squeeze his head between the others. He caught a quick glance at the ailing mice. 'Ugh,' he said. 'The foam has a greenish tinge.'
Harlan put his hands back into the gloves and picked up the first mouse. In contrast to its earlier belligerent behavior, it did not resist. It lay calmly in the palm of his hand breathing shallowly. Harlan put the animal down and reached for the one that had had the seizure.
'This one is dead,' Harlan said. 'Since it had been infected for the longest time, I guess that's telling us something.'
