When one of now (best) surgery student Julia's patients dies after a seemingly successful surgery, she refuses to accept from staff that it may have been nobody's or her fault, becoming obsessed with the idea that it was murder, which an autopsy she orders doesn't contradict. Reluctant Murdoch, who concentrates on inventions for their new home, comes investigate, discovering an unusual pattern of deaths among alcoholics in the ward, they work out who poisoned half a dozen. Crabtree has a brief courtship with a suspect: nursing student, Florence Nightingale Graham, but encourages her to sell a face cream she concocted; when it seems a success, she resigns nursing school to sell it under the name Elizabeth Arden and relocates to New York City to enter the cosmetics industry full-time.
