Ray Electromatic Mysteries (A. Christopher)

Ray Electromatic is a robot detective in a sort of 1960s noir alternative history, but being a private dick is actually a cover for the job that pays the electricity bills: Ray is really an assassin since being a robot gives him the “certain moral flexibility” of John Cusack in Grosse Point Blank. Sometimes clever, sometimes funny, and often contradictory, the books in the series are like episodes of Futurama were written by different people where the show runner didn’t check for consistency in Bender’s character. The Automatic Detective (see review here) has more LOL noir dialog and more science but Ray, like Bender, has his moments.
