Batman Vol 1 #407

Detective James Gordon and Sgt. Essen know the only way they can keep apart from each other is if Essen transfers to another department.

Meanwhile, it becomes more apparent that Batman is secretly in collusion with D.A. Harvey Dent. After a visit from Batman, Gotham's notorious drug kingpin Skeevers cops a plea deal to turn over evidence implicating corrupt cop Flass.

But this does not go over well with Commissioner Loeb, who tries to blackmail Gordon to back off or he'll tell Barbara about his affair with Essen.

Through it all, Gordon begins to suspect that Batman is Bruce Wayne, and Selina Kyle pushes herself to more daring crimes in order to usurp Batman in the headlines.
