Not to be confused with The League of Extraordinary Gentlemen: Black Dossier graphic novel.
The Black Dossier is a file created by MI5 on the secret history of the League of Extraordinary Gentlemen in all its incarnations. The Dossier contains a collection of numerous texts with different authors and formats.
The Dossier was first compiled by Gerry O'Brien for Harold Wharton on the history of the League and their exploits. O'Brien also comments several times that he is doubtful of the validity of several of the members stories.
The dossier was originally in the possession of the British Secret Service, until in 1958 Allan Quatermain and Mina Murray (who had by this time resigned from the league) stole it to find out how much MI5 knew about them. They took the book back with them to the Blazing World and giving it to Prospero. What happened with the dossier afterwards is unknown.
