4. Arkham

Complete story — includes the ending

Cobblepot offers Gordon help in stopping the future war. The latter learns of the Arkham Plan from Alfred, who states that Falcone and Mayor James are backing the project that will improve the Arkham District, as opposed to Maroni, who has another plan. An independent hitman starts targeting the city council members involved in both opposing sides of the Plan. After an armed robbery of Maroni's restaurant, Cobblepot is promoted to restaurant manager by Maroni, following the former's action of saving a bag of money and the death of the previous manager. Mooney pits two female singers against each other for her nightclub job opening, with the winner being Liza. To prevent the war, Mayor James holds a conference about a compromise on the Arkham Plan, that Falcone will handle small housing development projects and Maroni will be refurbishing the Asylum. Gordon urges Bruce not to lose hope in the city. Later, Cobblepot fatally poisons the restaurant robbers, who are revealed to have been hired for just that purpose by Cobblepot himself. Meanwhile, Barbara confronts Gordon about Cobblepot, telling him about her past with Montoya. She decides to end the engagement when he refuses to talk.
