that silica is to blame, but there is no medical literature on the subject. Andrew intends to investigate this further, since, if confirmed scientifically, it would enable those workers who are affected to seek compensation. Although Andrew and Christine have money troubles, their marriage is a happy one. At a dinner party hosted by a wealthy mine proprietor the Mansons are introduced to Professor Challis. Over dinner Andrew is encouraged to discuss his research. At home afterwards Andrew complains bitterly about the elitist attitudes and hypocrisy of their fellow diners. Andrew befriends Con Boland, a jovial Irish dentist and family man with five children. Andrew gains Con's support and hopes to gain the support of the other three medical assistants in his mission to refuse to pay Dr. Llewellyn 20% of their income. Episode 5: Andrew informs Dr Llewellyn that he intends to meet with the other medical assistants that evening and that he expects them to join forces in refusing to pay 20% of their income to him. However, to Andrew's dismay, during the meeting that follows he fails to gain the necessary support from his fellow medical assistants. In his despair at the hopelessness of his situation, Christine convinces Andrew to study for the M.R.C.P. qualification offering to help him with the language proficiency requirements. The arduous combination of work and study is stressful to Andrew, who takes his frustrations out on Christine. However, he travels to London and sits the examinations where his oral examiners are Sir Robert Abbey and Dr. Maurice Gadsby (both of whom feature again later in the series). He passes. Immediately on his return from London he is called to an accident in the mine, where, under dangerous and challenging circumstances, he amputates the trapped leg of a miner. Christine informs Andrew that she is pregnant. One morning, five months into her pregnancy, she mentions to Andrew that she is worried about the state of the bridge, and Andrew promises to ask the committee to do something about it. However, the bridge collapses when Christine is crossing it. Whilst Christine does not appear to suffer significant injuries to herself, she miscarries the baby and Dr. Llewellyn informs Andrew that she is unlikely to ever bear another child. Andrew's research into silicosis in anthracite workers is progressing well, and he applies for an M.D. on the basis of his thesis. His experiments involve testing
