In the BBC show 'Sherlock' I recall seeing the number 1895 frozen upon Johns laptop and later, in season three, in the episode 'The Abominable Bride' there is the theme of the 19th century. If I recall correctly, 1895 is in the 19th century. Could it have been, an easteregg, a hint for us to follow to find out of the past in order to know the future???
