Enola Holmes: 10 Things From The Books Not Included In The Film
8. Florence Nightingale
In The Case of the Cryptic Crinoline, Florence Nightingale appears in one of the stories as a seemingly invalid old woman, mentioned in connection to Enola's kidnapped landlady, the deaf war widow, Mrs. Tupper.
Despite largely being remembered as "The Lady with the Lamp", a Victorian figure of healing who ensured that soldiers were tended to during the Crimean War, Florence Nightingale was also a remarkable statistician, detail-oriented and disciplined in her work. Lesser known is her role in history pioneering modern data visualization with the use of infographics to express statistical data.
In the story, while initially introduced as a reclusive invalid, it's later revealed that Nightingale was a spy during her time tending to people in the war, and that she'd asked Mrs. Tupper to smuggle something back to England in her crinoline - which Mrs. Tupper was not aware of, due to her deafness, a message which caused her kidnapping.
Within the story, Nightingale also plays a part in helping Sherlock understand why Enola fears him so much despite her deep respect and adoration of him, and offers to shelter and care for Mrs. Tupper when Enola is forced to relocate after rescuing her from her kidnappers.
