a message from Holiday to Falcone. Meanwhile, the pistols left behind by Holiday and the bullets gleaned from Holiday's victims are traced to a Chinatown neighborhood, but the gunmaker is found dead as Holiday's victim on Mother's Day. On the following day, Dent follows up on Vernon's investigation and has Bruce arrested, claiming that as Bruce's father Thomas Wayne saved Falcone's life after he was shot, that Bruce is loyal to the Falcones. However, Bruce's butler, Alfred, testifies that Thomas Wayne's report never came to light due to police corruption, which helps declare Bruce innocent, especially in light of the murder of the Gotham City coroner on Independence Day. Sal Maroni, having been arrested earlier, offers to testify against Falcone after his father is killed on Father's Day. During the trial, he throws a vial of acid—secretly given to him earlier by Vernon—at Dent, disfiguring half of Dent's face. Dent is rushed to a hospital but escapes into the sewers, befriending Solomon Grundy when he encounters him. Gordon deduces Dent may be Holiday, but Batman refuses to believe it until he can talk to Dent himself. After Falcone's sister, Carla Viti, is murdered on Falcone's birthday in August, Batman questions Julian Gregory Day, the Calendar Man, on where to find Dent. Day suggests that, since it is Labor Day, Holiday will try to kill Maroni. Batman stages a plan with Gordon to move Maroni, giving Holiday the means and opportunity. During the transfer, Holiday murders Maroni, but Batman – having disguised himself as one of the security guards – takes him down. Holiday is revealed to be Alberto Falcone, son of Carmine Falcone, who had faked his death. On Halloween, Dent resurfaces as Two-Face. He releases most of the super-criminals from Arkham Asylum, then seeks out and kills both Carmine Falcone and Vernon, despite Batman's attempts to stop him. Falcone's daughter, Sofia, is also apparently killed in a struggle with Catwoman. His revenge complete, Two-Face turns himself into Gordon and Batman but tells them that there were two Holiday killers. Gordon is confused, as Alberto has already confessed to all of the killings. While Batman initially dismisses Two-Face's statement, he points out the fact that Two-Face, having killed Falcone and the last of his collaborators on Halloween, could technically be considered Holiday. While Two-Face is imprisoned at Arkham along with the recaptured criminals, Alberto can delay his execution based on
