Batman Issue 632

"Orpheus in the Underworld"
Black Mask disguises himself as Orpheus, and as such is forced to battle Zeiss, who was sent to kill Orpheus and other 'crime bosses' by grief-stricken Henry Aquista. When Batman arrives on the scene, he gets the better of Zeiss, but is distracted by a large explosive planted by the assassin which he must defuse. As he does, Black Mask deliberately allows Zeiss to escape. Through Onyx, he arranges for the transportation of a large machine for dispersing gasses, and then listens in as Batman gives his allies and police their orders for a final showdown with the gangs in Robinson Park.
