Could te recommend me a series to watch?

I Amore some tv shows about cops, FBI, lawyers and so on: White Collar, Castle, The Mentalist, The Good Wife. I'm watching Rokkie Blue now.

Also I like some medical shows, like Private Practice, and also I'm watching Three Rivers right now.

And I Amore period drama shows, like Downton Abbey.

And I don't like fantasy.

So, what are your recommendations?

PS: House, M.D. and Bones are in my lista already, I'm planning to see them.
