storyline Bruce Wayne had dinner with Councilman Waldemar and Stuart Bentley. The councilman boasted that during the last plague, he'd auctioned off the antidote after stealing it en route to a hospital. The only records were in a safety deposit box in a bank vault buried in the cataclysm. Oracle got Batman to the vault, but it had been completely looted. Babs also had a box there. Batman followed a lead to the Penguin, who sent him another lead: the third man at the dinner, Stuart Bentley. Batman got to him before Penguin's men could and recovered his loot. Barbara told Batman what was in the letter he'd recovered - it was from her mother to James Gordon explaining that he could be her birth father. She'd taken it from her mother before James could read it.
