Looking for Sherlock Holmes....

So does anyone know a good detective? There are a couple people who I don’t really know anything about that I would like to find more information on. What I do know is only hear-say. I have searched every website known to man on how to find someone but when you don’t know much about them it’s a bit hard. I know you probably have no idea what I am talking about but if you would like to help me or have tons of spare time to spend doing my dirty work, heck just ask and I’d be glad to let you know what I’m up to.
