Elegy is a 2009-2010 comic book story arc that ran in the main feature of DC Comics' flagship title, Detective Comics, from issues #854-860. It is written by Greg Rucka with artwork by J.H. Williams III, with colors by Dave Stewart.The story is notable for featuring the modern incarnation of Batwoman, replacing Detective's regular feature character Batman in the wake of that character's apparent death in the DC event series Final Crisis. Although a title had been in the planning stages since before the character's first appearance in 52, various production setbacks and DC events delayed the title until Bruce Wayne's removal from the present day DC Universe. Deemed the appropriate time, the story was placed as the main feature in Detective. Source: Wikipedia (en)
