Between drama and humor ...

One of the few Philip K. Dick novels not belong to the genre SF, "Confessions of a Crap Artist" went absolutely jubilant by baroque and colorful characters to haywire psychology. One soon realizes that the barjo in question (who must be 313 pages to realize that he is really barjo) perhaps is not the most barjo of all. His sister is probably not bad in the genre either: manipulative psychopath, conceptions of good adopted home life, explosive mix of superficial charm and inner vulgarity that makes life impossible for her husband, who falls into a manic depression that leads to murderous impulses ... Put all these people cohabiting, add two, three disruptive players and you get the explosive mixture that makes up this book. The result is tasty in the extreme.

Note that a French film version exists, released in 1992, which include playing Richard Bohringer and Jerome Boivin.
