Complete story — includes the ending
As news of Leopold and Loeb 's arrest hits the papers, Al Capone, still angry and grief-stricken over Frank's death, kills a policeman. Rothstein runs into Margaret at her work, which is not entirely above-board. Dunn deals with church concern about his heroin in the community. Willie drops out of college—infuriating his father—and turns to Nucky for work. After Johnny Torrio is arrested at a distillery that he just bought from O'Banion, he orders Capone to kill him. Roy helps Gillian kick her habit but confesses to an obsession of his own. Agent Knox is actually Jim Tolliver, as Gaston Means has secretly known all along. Daughter Maitland reveals that her true allegiance is to Dr. Narcisse—not Chalky—for horribly personal reasons.
