Quote context

[...]

- Where is Brown, when's he coming?

- How long we gonna stay here?

- We've been here two days, that's all.

- I just can't take it anymore, Fante.

- I tell you, my thumb's got an infection, it keeps aching worse than a sore tooth.

- If the cops catch us, it'll ache worse.

- Cops! What can they prove?

- They don't have to prove a thing.

- They got three warrants out for us, indictments for three murders.

- So, let them indict, they still can't prove... Can they?

- You know how long it would take for three murder trials? We'd be in jail for three years.

- Now relax. Brown will get us out of town until the heat blows out, then we can come back.

- How do we know we're safe here?

- It's the safest place in the world. Grazzi built this place in prohibition days. Not even the bellhops know it's here.
