- Rules of Engagement (#1-6) - Lovers & Madmen (#7-12)
There was an arc with a young (disco suit-wearin') Nightwing, before the Bat & Cat arc, though. I really hope they get on it and put them out soon.
But what's stupid (IMO), is that they don't call it "Batman Confidential: Rules of Engagement", it's just "Batman: Rules of Engagement". So they kinda get lost in all the other books that start with "Batman:".
