01E04 - Arkham

One by one, city council members are murdered by a 'pro'. A jailed mob hit-man identifies him by the common element, use of a sharp tube, as Richard Gladwell, or actually that city employee's murderer who stole his identity years ago. Oswald Cobblepot reveals his return in Gotham to highly unamused James Gordon and tips him off it's the precursor to a bloody gang war over 'Arkham', while sneakily working his way up from dishwasher to manager of mob lord Sal Maroni's HQ restaurant. After consulting Bruce Wayne and his butler-guardian-confident Alfred Pennyworth, Gordon realizes it's a fight between Falcone and Maroni, who both employ the same killer, over two alternatives for late tycoon Wayne's philanthropic project to renovate Arkham, Gotham's last derelict quarter, renovating both cheep housing and the mental asylum. James's spoiled fiancée Barbara Kean refuses to stay with him when he denies her confidential police information. Working out the mayor is the next target, Gordon steps in for the inadequate police protection.
