Shannon's Way
A. J. Cronin
 Robert trains to be a doctor at the fictional Levenford Infirmary (Levenford is loosely based on Dumbarton), and falls in love with Jean Law, a young medical student belonging to the Plymouth Brethren who rejects him when she discovers that he has deceived her about his history and religion (he is a Roman Catholic). He develops an interest in a disease contracted from infected cows' milk, and devotes his spare time to researching it: it turns out to be brucellosis. Dr. Shannon contracts a nervous breakdown when he completes the project only to find that someone else has anticipated his results, and is nursed by and marries Jean.
