The men and women of the Gotham City Police Department face challenges like no other cops - including the city's Dark Knight, Batman, and his deadly rogues' gallery! Detective Cris Allen's career is placed in jeopardy when a corrupt crime scene investigator steals evidence; the GCPD's relationship with Batman takes a turn for the worse; and Detectives Allen and Montoya are forced to travel to Keystone City to seek help from the villain Dr. Alchemy - and from the Flash - to save a fellow officer! Acclaimed authors Greg Rucka ("Superman") and Ed Brubaker ("Catwoman") are joined by artists Stefano Gaudiano ("Batman") and Kano ("H-E-R-O") for this all-new double-bill of noir-tinged police tales!
