Greg Rucka, Shawn Martinborough and Steve Mitchell become the new creative team with Detective 742 (March 2000), as the book regains it’s identity. In fact, under Rucka, the detectives of Gotham would rise to new prominence.
This issue is all about Commissioner Gordon, returning to work, but still deep in mourning. Batman follows him, observing, for much of the story, which deals with a murdered police officer.
Harvey Bullock gets promoted, becoming a lieutenant, and throughout Rucka’s run the actual positions of the various police would become more defined.
The murdered officer leaves behind a dying clue, TEC 472, written on his hand. For reasons I have never really understood, the abbreviation for Detective Comics has always been “tec.” Why it is not “Det,” when Adventure is “Adv” I have no idea, but it isn’t, it’s “tec.” So TEC 472 is not only a clue, but also the way the comic would be indexed, by geeks like me.
Mackenzie Bock, who is a captain on the force, gets a bit more status under Rucka, appropriate to his position.
And the new boy, Crispus Allen, becomes Renee Montoya’s new partner. Though considered prissy by the other cops, he shows his stuff in the interrogation room, getting the location of the killer.
It’s Gordon’s show all the way, though Batman does participate in the bug bust. Gordon chases down, and apprehends the murderer, without even firing a shot.
He is not painted as a super-human. The heroic is simply how he keeps going on.
