Issue: Detective Comics #800
Subtitle: Alone at Night
Date: January 2005
Weeks after the gang war ended, Batman began to find OD'ed junkies. Without drugs for so long, they took too much when they began to reappear on the streets. He beat up a dealer and got some names and locations. The drugs seemed to bear the signatures of multiple gangs in the city. He led the police to a cutting ring where he was astonished that it was Yakuza and not Triad or Escabedo.
Leaving, Batman realized he'd become to dependent on Oracle, who'd recently left Gotham City. Onyx had taken over for Orpheus, who'd become somewhat a martyr. Robin and Batgirl also left town. Alfred was tending to Dick, who was still recovering from his gunshot wound. Batman was back to being alone. He tracked down Mad Hatter. Killer Croc and Alexandra Kosov were at his side. Batman saved their hostage after learning Black Mask was their boss. He caught Catwoman up on what was going on.
