Sherlock, Series 1

Sherlock:
Ah, Anderson. Here we are again.

Anderson:
It's a crime scene. I don't want it contaminated! Are we clear on that?

Sherlock:
Quite clear. And is your wife away for long?

Anderson:
Oh don't pretend you worked that out! Somebody told you that!

Sherlock:
Your deodorant told me that.

Anderson:
My deodorant.

Sherlock:
It's for men.

Anderson:
Well of course it's for men! I'm wearing it!

Sherlock:
So's Sergeant Donovan. [sniffs] Ooh... I think it just vaporised. May I go in?

Anderson:
Now look, whatever you're implying-

Sherlock:
I'm not implying anything. I'm sure Sally came round for a nice little chat, and just happened to stay over. And I assume she scrubbed your floors, going by the state of her knees.

[Sally looks visibly embarrassed]
