Terminal (mis)diagnosis and the physician-patient relationship in LM Montgomery's The Blue Castle.

LM Montgomery's The Blue Castle was first published in 1926, yet contains many insights into medical practice that remain relevant today. The protagonist, Valancy, mistakenly receives a terminal diagnosis in a letter from her physician, who has sent her a note intended for another patient. Her interactions with the physician raise issues that are still relevant in contemporary medical education and practice, primarily the importance of effective communication in the physician-patient relationship, especially in the context of diagnosing terminal illness and handling a diagnostic error. The Blue Castle offers a useful starting point for debate and discussion in medical education about these topics.
