51.) Just as he does in the show, Sherlock repeatedly forgets Lestrade's first name in the books. (Trivia: what is his first name?)

52.) Benedict Cumberbatch read the Sherlock Holmes books, as expected, but Andrew Scott didn't, because he wanted a fresh take on the character and wanted him to be unique.

53.) A lot of the cast's family members guest star in the show including: Amanda Abbington (Mary), who is all Martin Freeman's wife, young Sherlock is Steve Moffat's son, and Sherlock's parents are Benedict's actual parents!

54.) The Empty Hearse is the most viewed episode.

55.) The Blind Banker is the least viewed episode. (This is my second least favourite episode.)

Yay Sherlock! I will be posting some more Sherlock facts eventually!
