Note: robbed Bruce Wayne's party
An unnamed thief was the apparently leader of a gang that infiltrated a lavish party at Bruce Wayne's mansion, dressed as the catering staff, and robbed the guests. The man was introduced by the narrative caption in panel 1 on page 3: "Then, appearing from the shadows, an immaculately dressed man, masked . . ."
The immaculately dressed man uses a loudspeaker to threaten party-goers: "As your wallets and jewels are being removed, please don't get any foolish notions . . . When the grains of sand from this hourglass run out, you can make a move -- the mines automatically will be rendered harmless! By then, we'll be far away!"
