So, uh. Fallen London. If, for whatever reason, you need to get into New Newgate Prison for a bit, but ideally you'd like to do it without acquiring a criminal record in the process, because those are awkward, apparently a nice, handy-dandy solution could be to try and rob hell?
Or rather, hell's embassy in London. And specifically, you need to fail to rob it. Because if you do that and get caught by the devils in the act, the resulting diplomatic snafu results in you being hastily shuffled out of sight and off to prison without any of that pesky stuff like due process.
Which would not normally be a good thing? But because this is going on up at the diplomatic level, it means that smaller people, like, say, the police and judicial system, continue to be blissfully unaware of your existence for a while longer.
Just, you know. As an idle note from someone who is currently staring out of a barred stalactite window? Again.
