- I'll have another one of those.

- I tell you, something very unpleasant is going to happen here tonight.

- Well, John, I'm going to bed. I think you should too. We'll do some more in the morning.

- Yes, of course. You must be tired, I'm sorry.

- Goodnight.

- Goodnight.

- What I don't understand, Mr Banning, is that if you hit him like you say you did, you must have killed him. You didn't do that, otherwise there would be a body. So, I must assume that you missed.

- I tell you, Inspector, I hit him, twice at least from here.

- At four yards?

- At four yards.

- I see.

- I see.

- Well, I've got men out there looking for him now. That's all we can do at the moment.

- I have one already.

- You have? Why didn't you say so?

- You wouldn't believe me.
