Miss Wenceslas:
[approaching Sherlock, who is disguised as a security guard] Don't you have something to do?

Sherlock Holmes:
Just admiring the view.

Miss Wenceslas:
Yes, lovely. Now go back to work. We open tonight.

Sherlock Holmes:
Doesn't it bother you?

Miss Wenceslas:
What?

Sherlock Holmes:
That the painting's a fake?

Miss Wenceslas:
What?

Sherlock Holmes:
It's a fake. It has to be. It's the only possible explanation. You are in charge, aren't you, Miss Wenceslas?

Miss Wenceslas:
Who are you?

Sherlock Holmes:
Alex Woodbridge knew that the painting was a fake, so somebody sent the Golem to take care of him. Was it you?

Miss Wenceslas:
Golem? What the hell are you talking about?

Sherlock Holmes:
Are you working for someone else? Did you fake it for them?

Miss Wenceslas:
It's not a fake.

Sherlock Holmes:
It is a fake. I don't know why, but there's something wrong with it. There has to be.

Miss Wenceslas:
What the hell are you on about? You know, I could have you sacked on the spot.

Sherlock Holmes:
Not a problem.

Miss Wenceslas:
No?

Sherlock Holmes:
No, I don't work here, you see. Just popped in to give you a bit of friendly advice.

Miss Wenceslas:
How did you get in?

Sherlock Holmes:
[scoffs] Please.

Miss Wenceslas:
I want to know.

Sherlock Holmes:
The art of disguise is knowing how to hide in plain sight.
