Denny O’Neil, Dustin Nguyen and Derek Fridolfs relate a decent one-issue tale, of a mystery that has puzzled Dick Grayson for many a year.
Dick Grayson is Batman in this story, but Bruce Wayne has returned. Because he has launched Batman Incorporated, he is busy around the world, so there is room for both him and Dick in the role. After fighting some hoods, Dick comes across a medallion in the refuse on a street. He recognizes it instantly, and Nguyen changes the art to a very child-friendly style for an extended flashback.
The Joker has stolen the medallion from the Order of St Dumas, and fights an early (but uncostumed) Azrael. Batman gets in the middle, and the flaming sword takes precedence.
Robin follows the Joker, and captures him, but the medallion is nowhere in sight. The Joker had bumped into a bum, Loomis, along the way. Loomis was arrested, along with the Joker and Azrael, but while they escaped, he went to prison for 25 years, protesting his innocence, even though the medallion was never found.
Dick finds the dying old man, assures him that his name will be cleared, and then finds the hoods and scares them into turning themselves and the medallion in.
Batman rushes back with the good news, only to find the Joker had been there first.
Lots of different moods in this story, and the art carries them all well.
