I need to get some air. We're going out tonight.

Actually, I've got a date.

What?

It's where two people who like each other go out and have fun?

That's what I was suggesting.

No, it wasn't. At least I hope not.

Where are we headed?

I need to ask some advice.

What? Sorry?

You heard me perfectly. I'm not saying it again.

Don't worry. Next date won't be like this.

Sergeant, we haven't met.

Yeah, I know who you are and I would prefer it if you didn't tamper with any of the evidence.

We're obviously looking at a suicide. It does seem the only explanation of all the facts.

Wrong, it's one possible explanation of some of the facts. You've got a solution that you like, but you are choosing to ignore anything you see that doesn't comply with it.

But if his door was locked from the inside, how did the killer get in?

Good, you're finally asking the right questions.
