I saw the episode once now.
I think I’m going to add new discoveries day by day till I got a DVD.

-Sherlock came into his flat with a bloody long harpoon
based on “The Adventure of Black Peter”

- I suppose I saw Sherlock is looking for some cigarettes in a Persian slipper.
Sherlock Holmes in The Canon has a habbit to keep them in the same one.

- John has a new laptop. Apple!

- I wondered why Sherlock drove a car. In The Canon “His Last Bow”, Watson drove a Ford car. I know the fact Martin Freeman doesn’t have a drivers’ license via Baker Street Babes Podcast. (20120116)

- The place Mycroft received an alert phone call is The Diogenes Club?

- The poisonous fog looks like the gas in “The Devil’s Foot”

- I feel the motion graphics of Sherlock’s “Mind Palace” are slightly exaggerated.

I can’t understand the whole story because the lack of my hearing skill of English. I’ll check the following again when I get Season 2 DVD in the end of this January. It has English subtitle. ;-D

- The ringtone of Moriaty: Bee Gees – Stay’n Alive
Literally they are.

- The case three geeks asked Sherlock:
The Geek Interpreter (John’s Blog)

- The case A female dead body in Barts:
The Speckled Blond (John’s Blog)

- “The Six Thatchers” in John’s Blog:
The Six Thatchers (John’s Blog)

- The case at a theatre:
The Alminum Crutch (John’s Blog)
This case exsists in The Canon “The Adventure of the Musgrave Ritual”
The theatre is on the “Strand”.
The Detective is “Sidney Paget” Of course he is a painter of The Canon.

- The thumbs Mrs Hudson found in the fridge is based on “The Engineer’s Thumb”
But I heard she said “thumbs”
The engineer lost only his left thumb.

- The word Mycroft said to Sherlock in The Buckingham Palace: How would you know?

-The words during Sherlock and John are fighting:
J: I was a soldier! I killed people!
S: You’re a doctor!
J: I had bad days!

- The word Sherlock open the safety box in Irene Adler’s House: Vatican Cameos!
I don’t know what it means.

- The word Irene said to Sherlock after he opened the safety box is fun: You’re so observant and flattered.
