"Dead Robin" from Gotham Central #33 (DC, 2005) by Ed Brubaker, Greg Rucka, Kano and Stefano Gaudiano
There's a big hole in my comics collection in the early 2000s that I've begun to fill out, and Gotham Central, the Batman-Lite Noir police procedural by the considerable talents of Brubaker and Rucka (and excellent artists very appropriate to the genre) is definitely on my must-read list, if I can put enough issues/trades together. Gotham has such a deep police force compared to any other comic book city, it's perfect for this kind of book. With all those costumed vigilantes swinging around, you'd think the GCPD could take it easy, but no. Gotham City is a hell hole.
