Bluff him.

Bluff

You can't really call it lucky that the police are after you, but their impeccable timing has just saved you from getting capped. Now if you can just double your luck with a clever ruse...

"Get your hands off me!" You shove Walter away and retreat to a safe distance. Pointing your finger menacingly at him and his posse, you explain the situation.

"Who am I? I'm someone who knows all about your little operation here. I know what you've done; I know that you've enslaved these women against their will!" It's a good thing your acting skills aren't too shabby, considering how ill-informed you really are.

Walter's eyes widen in anger...or shock...or fear...it's hard to tell. "Wh-what are you going to do? What do you want?"

"I want in, Malthus!" you bark, drawing the man's last name from a placard on the wall inside the mansion. Again, lucky that you're standing by the windows. "I want a piece of your gig, or else I'll have the police on this place like a priest on an altar boy."

"You can't be serious!"

Time passes as Malthus stands about nervously, hearing the sirens getting louder and louder, sweat beginning to bead up on his forehead.

He looks like he might crack, but you put the pressure on him anyway. "I could run circles around your house. That'll give this these cops plenty of time to see the rest of your machinations. Who's going to stop me? You? Your fifty-year-old servants? Don't even think about those pistols. The police will be very interested to hear where you got those suppressors."

"Alright! Alright!" he capitulates, "Whatever you want! Just get rid of them!"
