you could also try out Harlan Coben' Myron Bolitar and Win Spencer series.
other auhors that you might enjoy could be Greg Rucka's Atticus Kodiak series (one hell of a name for a character), and Stephen Hunter's Swagger series.
by far the best pairing i have read is the one mentioned by several before me, Robert Crais's Cole and Pike series. Crais' stand alone Pike novels are great books too, in fact i prefer those.
