Because Stephanie Brown has all of the best luck in the world, when she goes back to her dad's house (despite her mother pleading with her not to) she comes to find that her father is a criminal by the name of Cluemaster, and is currently meeting with the likes of Firefly, Lockup, Signal Man and a mysterious fourth man, who knocks her out form the shadows.
Back at the GCPD, the rookie officer Strode is speaking with Bullock, feeling like everything is about to get a whole lot worse, which he agrees to. Bullock and Major
With Carmine Falcone back in town, Batman takes a visit to the Gotham underworld, specifically to say hello to The Penguin, asking if he knows anything. It's clear Penguin doesn't know a thing, and given the history of what happened between him and Falcone five years ago, the only thing Falcone would come to him for now would be to put a bullet between his eyes.
Speaking of Falcone, he's present with Mayor Hady and meets with Forbes, who is very aware of who Carmine Falcone is, telling the mobster that he was a fan of how Gotham was run when the Falcone family was in power. So, with Gotham in need of a new commissioner... yeah, you get where this is going.
Back int he Batcave, Bruce is stilt trying to figure everything out about the train accident, but with nothing showing up in Gordon's blood tests, the question of how he seemed to have seen a gun on the man he shot at is still a big question mark. But that's going to have to wait, as Falcone's men start moving in one The Penguin's territory around the city, setting off alarms all over the place.
Back to Stephanie, as she starts to come to, the fifth villain still lurking in the shadows speaks of their plans and how deep they go, and the only person who knows of them other than those seated at the table is Cluemaster's daughter, so that's going to be a problem. An act of dedication is asked to be shown by Cluemaster, and being father of the year, it doesn't take much to convince him to put a gun to his daughter's head, telling her she's always been a disappointment. But, fearing for her life, Steph quickly pulls the pin on one of the gas canisters around her father's belt and makes a break for it.
After Batman beats up the thugs torching Penguin's territories, he finds that they were expecting to be caught, as they've got a message to deliver to him on behalf of Falcone: "We're the law now."
Penguin gets word of the Falcones moving in on his territory, but it's not just one, they're moving in on all of it, much quicker than anyone could expect, leading Penguin to realize the city just went to war.
With the city going to shit (again), Maggie walks into the GCPD to tell everyone to suit up, but Forbes stops them all. Followed by the Mayor, he's introduced to his fellow policemen as the new interim Commissioner, and what he says goes from now on. So instead of dealing with the gangs, Forbes refocuses all their attention on bringing down the real threat (in his mind)... Batman!
And as we saw in Batman #28, Steph knows everything, but now everyone wants to kill her, and her mom won't pick up the phone. Welcome back, Steph.
