Quote context

[...]

- I meant what I said about not seeing him. It's a violation of your parole.

- Now, run along, Wesson. And stay away!

- You can't tell me what to do. I can do what I like and go where I like and see any woman I happen to like. You have no authority over me.

- I have authority over you. Tell him to go.

- Please, Harry. Go.

- All right, Jenny.

- How did he know where to find you?

- I don't know.

- Well, what am I supposed to do? Hide?

- Now, you better watch your step, Miss Marsh.

- All right, I'll stay away from him, but you've got to help me. Can you get me a room and a job where he can't find me? Maybe. Report in the morning.

- Couldn't Monte have met us somewhere else?
