Detective Comics (1937) #822

 The team of writer Paul Dini (BATMAN: WAR ON CRIME, Batman: The Animated Series), artist J.H. Williams III (PROMETHEA, SEVEN SOLDIERS) and cover artist Simone Bianchi (SEVEN SOLDIERS: SHINING KNIGHT) deliver another intriguing tale of the Dark Knight!

    When a young socialite is murdered, her grief-stricken uncle turns to the newly reformed Riddler to find her killer.

No longer the villain of old, the Riddler has turned his brilliant brain to crime-solving, and to the surprise of both the police and Batman, he's actually good at it.

Has Gotham's most pernicious puzzler turned over a new leaf, or is it all a cover for a darker scheme?
