- Now, who had access to the candlestick?

- All of us. It was given to you.

- Yeah, but I dropped it on the table. Anyone could've picked it up. You, him.

- Look. We still have these weapons: the gun, the rope, the wrench, the lead pipe. Let's put them all in this cupboard and lock it. There's a homicidal maniac about.

- Good idea.

- What are you doing with the key?

- Putting it in my pocket.

- Why?

- To keep it safe, obviously.

- That means that you can open it whenever you want.

- But it also means that you can't.

- But what if you're the murderer?

- I'm not.

- But what if you are?

- Well, it's got to be put somewhere. If I've got it, I know I'm safe.

- We don't know that we are.

- I've an idea. We'll throw it away.

- Good idea! Wonderful! Right away! Brilliant! That'll do it!

- Sorry. Can we help?

- I'm sorry. I didn't mean to disturb the whole household, but my car broke down out here, and I was wondering if I could use your phone.

- Just a moment please.

- Very well, sir. Would you care to come in?

- Well, where is it?

- What, the body?

- The phone. What body?

- There's no body. Nobody. There's nobody in the study.

- No!

- But I think there's a phone in the lounge.

- Thank you.
