By now, DC characters have become a kind of repertory company. The trick, for comics creators, is to find roles for them that both exploit their trustworthy familiarity and give them surprising things to do. Loeb (Batman: The Long Halloween) does his bit by supplying a rapidly unfolding plot in which caped crime fighter Batman battles Killer Croc and Poison Ivy. Simultaneously, he's pursuing and lusting after the lusciously amoral Catwoman, whom he teams with in a rousing (though improbably evenly matched) brawl with Superman. Other familiar characters make cameo appearances throughout. But Batman is actually following someone else's script; a mysterious, bandage-swathed observer is toying with him and the others. Readers can guess who this master manipulator is, but the real puzzle is what kind of game he's playing.
