9. Sir Arthur Conan Doyle & Sherlock Holmes
Given the chosen time setting, it was inevitable that Sony would introduce some of the culturally significant points into the game's universe to go alongside the scientific anchor points and the real figures. The most noticable is the presence of Sherlock Holmes and his creator, who are subtly hinted at. It's fairly heavily hinted that the police commissioner - one Commissioner Doyle - is either based on, or is explicitly Sir Arthur Conan Doyle, and the likeness of the character to Doyle as a young man is striking (though the longer "legs" to his moustache aren't entirely accurate, but this is an alternate time). In Chapter 10 there's also a fairly explicit nod to the great detective when Galahad paraphrases the commissioner, mentioning to Alistair that he has a tendency to refer to things as "elementary".
