Moriarty is standing outside 221B Baker Street. Presumably he is the one holding the camera and is filming the entrance door.

Moriarty: (Whispering) Who lives in a house like this?

Camera flashes static for a second and returns to a view of the door.

Moriarty: It’s only me…

Camera cuts to a view of the reception hall.

Moriarty: How clean is your house?…I smell baking…it’s apple pie. The glorious Mrs Hudson.

Camera view going up the stairs.

Moriarty: (In a sing-song tone) Hellooo.

Camera cuts to a view of the living room.

Moriarty: (Looking at the wallpaper, sounding disgusted) God, look at the wall. So here we are, Sherlock Holmes HQ.

Camera closes in on a table. There is a music manuscript on it it, [bad word] by Sherlock.

Moriarty: Oooh, too many notes.

Camera cuts to a view of the top of a drawer. There is a pack of cards, 4 dice and other miscellaneous random items.

Moriarty: Boring…boring.

Camera cuts to a view of a bison skull hanging on the wall. Sherlock has put headphones on it.

Moriarty: (Amused) He’s put headphones on. Good God.

Camera swivels around to view of the bookshelf.

Moriarty: Books, books, books…

Camera cuts to view of the knife still firmly nailed to the mantelpiece from “Study in Pink” 

Moriarty: What have we got here? (Closer camera shot of the knife) Temper, temper, temper.

Camera cuts to the infamous skull.

Moriarty: (Almost incredulously) skull?! (Ponders) I wonder what your skull would look like on my wall? 

Quick camera cut to a view of the kitchen floor, then camera cuts to a painting of a skull hanging on the wall.

Moriarty: More skulls…more skulls.

Camera quickly cuts to some pictures on top of a drawer, then cuts to a glass case displaying bullets. Under the bullets are labels saying “9mm Auto”, “.45 Auto Magnum”, “10mm Auto”, “.455 Rev”, “.45 Auto”, “.38 Rev Target”, “.38 Rev Drill” and “.380 Auto”.

Camera cuts to a focus shot of a sudoku [bad word] s cube.

Moriarty: (Sarcastically) How the hours must fly by.

Camera cuts to a view of the skull on the mantelpiece again.

Moriarty: Alas, poor Sherlock. I knew him well

Moriarty sniggers to himself as the camera view slowly pans up back to the painting of the skull.

Moriarty: Time to go, time to go…

Moriarty starts to laugh sinisterly and the sound of the laughter echoes as the camera view finally focuses on the shadow Moriarty has cast on the wall.

The picture goes pitch black suddenly.
