Batman: Whatever Happened to the Caped Crusader?

Blurb

"Whatever Happened to the Caped Crusader?" is a 2009 story featuring the DC Comics character Batman. The story is published in two parts, in the "final" issues of the series Batman and Detective Comics, released February and April respectively. Written by Neil Gaiman, pencilled by Andy Kubert, and inked by Scott Williams, the story is purported to be the "last" Batman story in the wake of severe psychological trauma that Batman endures within the Batman R.I.P. story, and his ultimate fate in Final Crisis.
The story's title is a reference to the backup stories published in DC Comics Presents from the early 1970s to the mid-1980s akin to writer Alan Moore's "last" Superman story Whatever Happened to the Man of Tomorrow?.
