Adelaide stirred, and opened her eyes. ‘Leonard?’ she said. ‘What is it? Why have you stopped?’
Dr. Petrie looked up. Then he nodded towards the distant skyline. Adelaide blinked her eyes and peered into the gloom.
‘Leonard…’ she said. ‘That’s New York! Leonard, we’ve made it!’
She reached over happily and kissed him. But he gently pushed her away, and pointed out into the dusk.
‘Look again.’
She frowned. ‘What’s happened?’ she said. ‘Where are the lights?’
He shook his head. ‘They could have had a power failure. It’s happened before.’
Adelaide stared at him. There was an uncomfortable silence between them that was prolonged by their mutual refusal to acknowledge what had happened. Finally Adelaide said, ‘It’s the plague, isn’t it? They’ve caught it here.’
Dr. Petrie nodded. ‘Yes,’ he said huskily. ‘I expect they have.’
‘What are we going to do?’ she asked. ‘Oh God, Leonard, we can’t go on running away for ever. The plague seems to spread faster than we can move.’
Dr. Petrie coughed. ‘I don’t know. I just don’t know what to do. I suppose in the end we’ll catch it like everybody else.’
‘We haven’t caught it yet.’
Dr. Petrie stared at the dribbles of rain coursing down the windshield. ‘I don’t know whether that’s a blessing or not. What’s the use of staying alive when there’s nobody else around to make it worthwhile? What does a doctor do when all his patients are six feet underground?’
Adelaide leaned over and kissed him. ‘Leonard, you’re tired. You’ve been driving for days. Don’t get depressed.’
Quite unexpectedly, Dr. Petrie found himself weeping. It was years since he’d last cried. Adelaide watched him tenderly and said nothing.
‘I’m sorry,’ he said, blowing his nose. ‘That was ridiculous.’
Adelaide shook her head. ‘No, it wasn’t. You have a lot of things to cry for.’
‘It doesn’t help solve our problem.’
‘It might do. It might stop you from bottling all your feelings up, and turning yourself into a nervous wreck. You’ve had so much to contend with.’
‘I’m a doctor. Doctors don’t get sick.’
Adelaide smiled. ‘Don’t you believe it.’
Prickles, who had been sleeping on the back seat, stirred and yawned. ‘Is it time for Star Trek yet?’ she said, sitting up.
Adelaide pulled a face at her. ‘How can you watch Star Trek in a car?’
‘I forgot,’ said Prickles, rubbing her eyes. ‘I was having a dream I wasn’t in a car.’
‘Anyway,’ said Adelaide, ‘having no television is probably the best thing that ever happened to you. All that garbage they put on for kids. And think of your health. Think of all that radiation you get from sitting in front of color TVs. Not to mention the eyestrain.’
Dr. Petrie was just about to start up the car again, but he paused. He turned to Adelaide and said, ‘What?’
She was confused. ‘What do you mean?’
‘What was that you just said?’
‘I don’t know. Eyestrain, something like that.’
‘Before that.’
‘Oh, you mean radiation?’
‘That’s right. Radiation! Radiation from color TVs!’
Adelaide said brusquely, ‘I wish you’d kindly explain what radiation has got to do with anything.’
‘I don’t know precisely,’ said Dr. Petrie. ‘But do you remember what they said on the radio about certain people being less prone to plague than others? Children was one category, and so were ConEd powerworkers, and doctors.’
‘You’ve lost me.’
‘No, it’s very simple. That was what I was trying to work out before. I was trying to think why Anton Selmer and I should both escape the plague, even though we were heavily exposed to it. There were one or two other doctors at the hospital, too, who seemed to be immune. Now you mention children, sitting in front of color TVs. How many hours of television does the average American kid watch per day?’
‘Don’t ask me. Six or seven?’
Dr. Petrie nodded. ‘Right – that’s a lot of television, and a lot of radiation. And that’s what Dr. Selmer and I had in common, and what we’ve all got in common with certain types of power workers, and others. We were supervising X-Rays, and we must have picked up a mild dose of radio-activity.’
Adelaide thought about it. ‘It’s a theory, isn’t it?’ she said. ‘I mean, it’s better than no theory at all.’
Dr. Petrie started up the car, and they pulled away from the curbside.
‘It could be nonsense, but it’s the only thing that seems to fit. I mean, if the plague has been mutated into a super-plague, maybe it was mutated by radio-activity. In which case, radio-activity seems to be the only thing that can ward it off.’
They drove through the rain towards the Holland Tunnel entrance.
‘Are you going into Manhattan?’ Adelaide asked.
Dr. Petrie nodded. ‘I guess we have to. They can’t have had the plague for very long, and if I’ve got some kind of theory about curing it, I think I really have to tell someone.’
‘But Leonard—’
‘What’s the matter? Don’t you want to go?’
‘Leonard, it’s not a question of wanting to go. Look at it – it’s dark and it’s getting darker. That city’s bad enough when it has lights. It’s going to be a jungle in there. You can’t take Prickles into that.’
Dr. Petrie slowed the car and took a long left-hand curve. The rain fell through the light of their headlamps in a careless pattern.
‘Adelaide,’ he said quietly, ‘I don’t see that we have any choice. All we have to do is find someplace secure to stay for the night, and then tomorrow we can get in touch with the hospitals. As long as I can tell someone about this radiation theory, we’re okay. Then we can leave.’
‘Leonard,’ said Adelaide, ‘I’m frightened. Can’t you understand that?’
He glanced at her. ‘Don’t you think I’m frightened, too?’
‘Then why go? We could skirt around New York altogether, and drive up to the Catskills. We could be safe there. You said before that we were going to find ourselves a place to stay until the
