O'Leary works the hospital corridors with the weary patience of a man who has learned that important things get forgotten and that keys vanish at convenient hours. He badgers Miss Keate about the missing south-door key, then shuts himself in the inner office to think, linking the crimes to the radium and to whoever slipped through the south wing at midnight. His willingness to suspect doctors, nurses, and neighbors alike keeps the investigation moving even as it strains the nerves of everyone around him.
