This issue is the very definition of story-telling that treads water. All we learn is what we know - Ghostmaker is a former "schoolmate" of Batman and they had a deal that Ghostmaker is now breaking. The deal? They keep out of each other's way. Oh, and Bruce apparently misses his old friend. Well, politics will do that.
Clownkiller still wants to kill Harley, and We now know that Oracle is called Batgirl Prime and Steph and Cassie are "The Batgirls."
We do see that Ghostmaker is scaring the crooks into giving themselves up and returned Mr. Pyg to Arkham. He was free for eight months. That really does make him better than Bruce at fighting crime. Pyg is a dangerous mass murderer (and frankly, a boring "gimmick" villain who shocks only because of his body count. I maintain that's not a good character.) Will Bruce say he knew where Pyg was, but needed him free to stop someone from stealing the election or selling nukes to some hostile power? Because letting a monster like that roam is just a bridge too far. If he didn't know where Pyg was, then Ghostie is better.
The whole issue ends with Clownkiller about to kill a tied up Harley. We get the sense that she helped kill people he cared about, and that's the problem with Harley. Her body count is problematic when trying to make her a hero for the kids.
We are pretty much right where we were last issue, but $4 poorer. That's not good story telling. Not a fan of this issue.
Or I could be wrong.
Was Grifter in it? He's the only interesting thing happening in this title. Seeing Harley on the cover is a good enough deterrent for me.
