"Blood Walk (1987, 1988) - Two novels about San Francisco vampire cop Garreth Mikaelian: Blood Hunt and Bloodlinks. As far as I can tell, author Killough was the first to create a vampire detective."
"Nick Knight (1989) - Los Angeles vampire cop Nick Knight was the first TV vampire detective. Nick Knight is the TV movie that became the TV series Forever Knight."
"Forever Knight Season Three (1995) - The season that killed off Nick's beloved cop partner Schanke in the name of 'retooling' and ended with a shocking and controversial series finale."
"Vampire Files Volume One (1990) - The first three novels about Chicago vampire PI Jack Fleming: Bloodlist, Life Blood, and Bloodcircle. Set in the 1930's and written in a Raymond Chandler style."
"Angel (1999-2004) - Los Angeles vampire PI Angel helps the helpless and seeks redemption for past misdeeds. Started with a modern noir style but evolved to become an action-adventure fantasy."
"Already Dead (2005) - Manhattan vampire PI Joe Pitt solves cases while trying (failing) to stay out of the way of NYC's warring vampire clans. Horror-noir in a Quentin Tarantino-does-hardboiled style."
"The Nymphos of Rocky Flats (2006) - Denver vampire PI Felix Gomez solves cases that are part hardboiled, part softcore, and always humorous (though not as farcial as the book titles might suggest)."
"X-Rated Bloodsuckers (2007) - Felix Gomez #2. Felix battles vampires, sleazy porn produers, and sleazier politicians in Los Angeles. Best book of the series."
"Moonlight (2007) - Los Angeles vampire PI Mick St. John helps the helpless, seeks redemption for past misdeeds, and romances a beautiful reporter that he rescued as a child."
"Angel of Vengeance (2011) - Los Angeles vampire PI Mick Angel helps the helpless... uh, same as Moonlight but minus the beautiful reporter. Like the Vampire Files, written in a Raymond Chandler style."
