Here are links to PDFs of a few Companies I have been working on.
My first inspiration was to represent Clive Cussler's fictional Van Dorn Detective Agency with its hero Isaac Bell. Cussler, of Dirk Pitt fame, has written--what?--five or six books in this series.

I've tried to turn them into a master-criminal ring in their own right: Annie Diamond's Forty Thieves.

It's a mix of fiction and fact, and, I think, has more personality than Cussler's very dry Van Dorns. Plus I threw in a female agent with Mystic Powers just for fun.
http://wrgmr.com/pinkertons.pdfFinally, just for fun, I took the characters from one of my favorite series of books, Jim Butcher's Dresden Files, moved them back in time a century, and created a Company ready to take on all comers from the Mystical to the Supernatural. It's called the Chicago Police Special Investigations Division, but it's really all about Harry Dresden, Wizard, er, uh, I mean, Mystic. And about a dozen special Talents and Mystic Powers.
