There's a scheme on to get the stuff, when who should come on the scene but our little party, and that makes 'em all nervous, 'cause Monty's a bad man to be up against.

Remember: she claimed that she knows Monty and he knows her.

She means by that that he knows she's a desperado, and she thinks he'll draw the line at a trip that promises murder and blackmail and such like dirty work.

So she puts a scare into us with a view to our throwing a scare into him.

If I scare any one, it's going to be that dame herself.
