Batman/Superman Vol. 4: Siege

Who is Superman�s Joker? Writer Greg Pak (ACTION COMICS) and artist Ardian Syaf (BATGIRL) add a deadly new name to Superman�s Rogues Gallery-one that will test Superman�s strength and Batman�s mind equally! It�s the Man of Steel�s worst nightmare: an obsessed villain who knows all of Superman�s secrets and is willing to kill all of his allies in order to destroy his true target. It falls to Batman to track down this murderous madman-but with no clues left behind and no leads to follow, will this killer outwit the World�s Greatest Detective? Collects BATMAN/SUPERMAN #16-20, BATMAN/SUPERMAN ANNUAL #1 and BATMAN/SUPERMAN: FUTURES END #1!
