Batman: Bad Seeds – Gotham Central #1

Synopsis

A killer is on the loose, someone is stalking Arkham Towers' Dr. Zeller, the subways are out of control, and Anarky's just pulled a big-time heist! With Vandal Savage diverting the GCPD's resources to his single-minded war against the Bats and the Bat-Family trying to stop Poison Ivy while evading the GCPD, there's almost no one left to do actual police work! Looks like officers Gordon and Espinoza have their work cut out for them.
