I'd been travelling pack through the pages of the book sub-forum seeking a Detective genre thread, this one appears close enough to suit.
First, I'd add a couple of heros, George C. Chesbro's Mongo series and Andrew Vachess' Burke series. Mongo, someone I haven't encountered in years incorporates the supernatural into the tale, while Burke is an anti-hero fixated on going after pedophiles.
I'm reading Tim Cockney's Backstabber at present, featuring undertaker/detective Hitchcock Sewell, based in Baltimore. Nice read so far. The patter strikes me as being more southern than I'd anticipated, but maybe Maryland is the south more than I'd credited it with being.
As almost always with detective heroes, this guy peppers the tale with musical references, a staple for the genre, both private eye as well as regular cops like Ian Rankin's Inspector Rebus series based in Scotland and John Sandford's Lucas Davenport series set in Minneapolis. Vachess' Burke has a thingy for blues which translated into the real world, me having encountered and bought a CD of songs mentioned in the books. Hitchcock's taste, or at least expressed knowledge of music seems more eclectic than most other heros I encounter, who tend to focus on one type of music, be it blues, jazz, or rock. Detective heroes also feel compelled to share their favorite brands of booze, not infrequently in a refreshingly low brow manner such as sucking down a brew such as Hamms, Busch, Pabst, or Rainier
