Southsea, Portsmouth, Hampshire, is significant to Sherlock Holmes (2009) because Arthur Conan Doyle, the author of Sherlock Holmes, started his medical practice there and wrote "A Study in Scarlet." "A Study in Scarlet" was the first introduction of Holmes and Watson; Doyle wrote this novel during his free time since his medical practice wasn't the most successful. This novel, along with "The Sign of Four," started his successful career as a writer. I found this information from a tourist website titled "Geeky Tourist". This source is an example of a gatekeeper and single authorship because it only allows one person to edit the information, and outsiders are not allowed to make any changes. Mapping this location on Cove adds grassroots layers to the story by showing where such an iconic novel/movie started.
