Batman 6 - The Dark Knight

Read Batman 6 - The Dark Knight Storyline:

The Dark Knight
A light shines over Gotham, a light that projects the symbol of a bat. The citizens who embrace it have accepted a masked crusader as their protector, while the criminals and corrupt who shun it are prey to the Dark Knight.
The Batman continues to wage his war on crime, reigniting hope in the city and inspiring others, like newly elected district attorney Harvey Dent. Regarded as the White Knight who will be at the center of the city's resurrection, Dent is ready to carry on Batman's fight. But before Batman steps aside, he sets his sights on dismantling all of Gotham's organized crime.
With the help of his trusted allies, Alfred, Lucius Fox, and Lieutenant Jim Gordon, Batman corners the mob, giving Dent the opportunity to convict them all. But in the mob's wake, a new class of criminal is on the rise, one that can't help but laugh as he drives Gotham's elected savior to the edge of insanity and forces the Dark Knight ever closer to crossing the fine line between hero and vigilante.
Behold the Joker
