I don't know much about the noir genre, but I checked out a new graphic novel called Dark Heat by Barry Graham and Vince Larue because I like Vince's beat-inspired writing and artwork, which often emphasizes themes from Michael McClure and Gary Snyder. Vince Larue also drew a very cool cover for my 2011 Kindle book about poker, The Cards I'm Playing: Poker and Postmodern Literature.
It's a strange leap that Larue makes from Snyder-inspired Zen Buddhism to macabre mystery comix, but Dark Heat shows many familiar influences, and also touches upon psychological and spiritual themes that remind me of The Sopranos, Psycho, Paul Auster, The Watchmen, Fletch, Taoism and a whole lot of good movies that have Steve Buscemi and/or Viggo Mortensen in them. This story begins in gritty realism, and ends with a postmodern exploration into what's real and what's not. For your noir pleasure: Dark Heat by Barry Graham and Vince Larue.
