When Andrew arrives in London, his infatuation with the lives and practices of Doctors Ivory and Deedman cast a very large shadow upon his life. Andrew covets what they represent and the values they hold dear: “He listened with interest when Ivory and Deedman, two well-known and successful doctors, talked loudly about their medical experiences. He said to himself: 'I must get to know these men better. They're so rich and successful!” It is clear that Deedman and Ivory represent the values of materialism and economic wealth. These ideas influence Andrew as they set him on a path of not settling for a life of destitution. Rather, Andrew recognizes that, like them, he wants to use his medical expertise as a way to generate money.
Another value that the London doctors have on Andrew is how they make their money. Andrew is intrigued by the development of this little community of doctors that are able to derive new and efficient ways of making money:
“I played a clever trick the other day,' said Ivory. 'I persuaded a patient to have a course of 12 treatments. I told him that the usual charge for this was fifty pounds, but that I would be willing to reduce the price to forty-five pounds if he paid me immediately. He gave me a cheque at once!'
'That's the way to make money!' Freddie laughed. 'And a bottle of medicine would have done him just as much good!”
The idea of being able to "con" patients so that doctors can make more money influences Andrew. Andrew realizes that he is able to use his influence in procuring more money from patients. This value influences his life when Andrew tells Christine to mix the medicines while he is seeing more patients, even having to use "coloured water" if she must. In this light, the materialist personality of the London doctors is shown to exert a major influence and role in Andrew's life.
Finally, the lack of value that the London doctors place on the lives of their patients holds a tremendous influence on Andrew's view of medicine and his place in it. When Vidler dies on the operating table, Andrew knew the truth. Medical incompetence killed a patient: “Andrew was almost blind with anger. 'You know that it's the truth. You did the operation so badly that it was almost murder!” This influences Andrew's life when he decides that he must turn away from making money at such a driven pace. Andrew tells Freddie that he is "tired of all this" in terms of making money. He also makes it clear to Freddie that Andrew feels there is something wrong in a system where the only focal point is to generate wealth: "There are too many doctors whose only thought is to make money.” In seeing how the London doctors operate, their lack of values casts a very large impression on Andrew and compels him to change his approach to administering medical services to his patients.
