Quote context

[...]

- Saul?

- They didn't tell you about Saul?

- No, they didn't.

- Saul is the worst, you know.

- We have to watch him because you see, he wants, he just wants to destroy, to kill. Poor Saul.

- Where is he?

- I know where he is. He's upstairs behind that bolted door, isn't he?

- Yes, locked in.

- Saul is why we have to keep Morgan.

- But if he did get out?

- Saul quite certainly would set fire to the house. He tried to once before. He wanted, he said, to make this house a burnt offering.

- But isn't he safely locked in?

- Yes, but you see, if Morgan is bad, I think he might open the door.

- Philip, what if he's come to?

- Wait here, I'll go down and look at him.

- He's gone upstairs. I heard him. He's gone to let Saul out.

- Wait for him downstairs and kill him.

- What are we to do? Can't we stay in here?

- No supposing he set fire to the place. Come on.
