Whatever Happened to the Caped Crusader?

All this post-modernist talk on Friday began to remind me of a certain comic book I once read called Whatever Happened to the Caped Crusader. It was a short Batman comic book written by Neil Gaiman. Neil Gaiman is very popular in post-modern culture and for him to write a batman comic book was very surprising to me.
The story begins at Batman's funeral and everyone, friends and foes alike, are there. Slowly each friend and foe tells their story of how Batman died. Alfred claims that after Bruce Wayne's parents were shot, he and a group of his friends pretended to be all the villains that Batman thought were real so that he would feel that taking on the role of batman meant something. Sadly, one of Alfred's friends goes insane and shoots Batman in the head. Catwoman comes to the front and tells a different story. She says that she found Batman bleeding on her couch in her living room after swearing off crime. The Joker tells an even different story, claiming that he poisoned Batman.
Each villain and friend of Batman tells a story of how Batman died, each one completely different from the last.
The first time I read this comic, I was very confused. I then asked my brother who checked out the comic, and who was an avid Neil Gaiman fan, told me that it was story about stories. It said that no matter how different one story is from another, the principles remain the same: that Batman was a noble and heroic person.
I feel that this relates greatly with post-modernist views: about how we try to break things down into their most basic elements. Everything is complicated and can't be fully understand, much like Batman and his multiple deaths.
