Batman: Murder at the Circus

Bruce Wayne receives a second riddle from Edward Nygma and consults Dr. Chase Meridian, who establishes that whoever is leaving the riddles is a "wacko" who is obsessed with Bruce. After this, Bruce invites her to the Charity Circus. Two-Face and his thugs arrive at the event, firing guns and terrorizing the audience. They also bring a bomb that Two-Face will detonate if Batman does not reveal his identity at the circus (Two-Face blames Batman for failing to thwart a criminal who threw acid on Dent's face, disfiguring him). The Flying Graysons, the circus acrobats, work to remove the bomb through an opening in the top of the tent. The youngest member, Dick, manages to push Two-Face's bomb out of the circus tent and into the water surrounding the tent by going ahead of his family. When he returns, he finds that Two-Face has killed the rest of his family by shooting up the wires that they were climbing on, sending them plunging to their deaths. Feeling sorry for Dick's loss and feeling responsible for Batman's failure to show at the circus, Bruce takes a reluctant and devastated Dick in as a foster son.
