Deadmines, Part Three?

Objectives
Find Marcus "Bagman" Brown outside the Deadmines in Westfall.

Description
I've heard suspicious rumors of movement in the Deadmines. After everything you pulled off in the Wailing Caverns, you'd be the perfect person to look into this! I have a friend in Westfall. He may not look like much, but he's quick as a whip and may have more information on what is happening in Westfall. We've already dealt with the Van Cleefs... twice. So what could be making that sort of ruckus down there?

I don't know nothing about nothing! Better get going before my shiv finds your face! Don't test me, cause I ain't all that bright!

Oh, Breanni? Yeah, sure! She's an old friend!
