Andoman Islands
From Tardis Wiki, the free Doctor Who reference
The Andoman Islands were the location of Port Blair.
Richard Carnac Temple was the recognised authority on the Andoman islanders, and he co-wrote a treatise on their language. In Arthur Conan Doyle's The Sign of the Four, Sherlock Holmes's description of the islanders drew from Temple's accounts. (PROSE: The Book of the War)
Behind the scenes
In the real world, the name of the islands is spelled "Andaman"; however, due to Tardis Wiki rules, the apparent typo in The Book of the War is regarded as their name in the Doctor Who universe.
