First appearance: the patient in room 18
As a major figure in The Patient in Room 18, Dr. Louis Letheny is not background color—the story leans on what they do once the chapter opens.
Head doctor; observes everything through cigarette smoke; plays a piano piece that intensifies the oppressive mood.
Dr. Letheny is felt everywhere in the early chapters — in the patients who were under his care, in the cottage where his daughter waits, in the car Jim Gainsay borrowed, and in the corridor where Miss Keate learns the news. His absence is the wound around which the other characters organize themselves, and the question of what happened to him shadows every conversation about the radium, the missing key, and the figure who moved through the south wing at midnight. He never appears on the page, yet his fate is the engine of the book.
