The end credits note that the game was based on a novel by Jalil Amr
. This doesn't refer to a published novel, but to something along the lines of fanfiction. Emailing Frogwares for more information about it, would result in a reply from the company's CEO Waël Amr
stating: "The author wishes the novel not to be public and anyway it’s in French!"
Much of the game takes place at Sherringford Hall. Sherringford Hope (or Holmes) and Ormond Sacker were Sir Arthur Conan Doyle
's original name choices for Sherlock Holmes and Dr. John (or James) Watson.
