To his great pride, Andrew was now a doctor in one of the oldest and most famous hospitals in London.

The Victoria was certainly old. The building was in a noisy, dirty street and it rarely saw the sun, even in summer. The department in which Andrew worked smelt of old age.

Andrew worked at the Victoria on two afternoons a week, and all his patients had some form of lung disease. But, though he was excited about his new appointment, Andrew could not put his heart into his work. He had lost interest in his coal dust discoveries. He had more important things to think about now! He decided that it was not worth his time and trouble to make a thorough medical examination of every person who came to see him. Instead, he took a quick look at each patient, and then gave him or her a bottle of medicine.

Six weeks after he started work at the Victoria, Andrew received a letter from Denny. He gave a sudden cry of pleasure. 'He's coming home - to work in England. Heavens, it will be nice to see him again, Chris!'

She was as pleased as Andrew was - but for a different reason. She had always felt that Denny and Hope had been a good influence on Andrew, and she hoped that Denny might influence his behaviour now. 'I think that I will invite Denny and Hope to dinner next week,' she said.

'All right,' he replied, 'but they will have to come on Sunday. I'm too busy during the rest of the week!'

On the following Sunday, Denny arrived. He looked older, but seemed to be happier. Yet he was the same Denny.

'This is a very grand house!' he greeted them. Then, turning to Christine, he added: 'And who is this well-dressed gentleman? Is he Dr Manson?'

Seated, a moment later, he refused a drink. 'No, thanks. I don't drink now. I'm going to settle down.'

He told them that he had found himself a good post at a country hospital.

Andrew looked at him quickly. 'You shouldn't bury yourself in the country, Philip! With your degree, you could get a much better post in London. Come to London!'

'What have you been doing to him?' Denny asked Christine. 'He doesn't sound like the man who blew up that sewer with me at Drineffy!'

At that moment Hope arrived. He and Denny had not met before; but they liked each other at once. Five minutes later, as they sat down to dinner, they began to joke about Andrew's success to his face.
