||Tim Van Patten
||September 8 2013
||February 1924. Nucky, preferring to stay in his room up in the Albatross Hotel and away from the boardwalk, comes to a peace agreement with Masseria and Rothstein. Richard, on his way home to reunite with his sister, leaves some corpses in his wake. Gillian, still an addict but desperate to get her grandson back, is resorting to prostitution until a stranger shows up with a better offer. Revenue Agent Sawicki's new partner, Warren Knox, isn't as naive as he acts. Chalky tries to coolly run the Onyx Club, but his right-hand man, Dunn Purnsley, gets into a mess of trouble with a booking agent and his wife.

||Chalky is pressured by Valentin Narcisse, a Harlem kingpin who knows what Dunn did. At home, Van Alden must deal with his stubbornly middle-class wife; at work, he has to deal with an angry Al Capone. Knox's true boss, it turns out, is J. Edgar Hoover. Before he leaves for Florida to visit an old friend, Nucky has to placate a frustrated Eddie and gives him a promotion. Valentin Narcisse puts an end to the conflict with the booking agent's wife by having her killed by his men.

Gillian, desperate to regain custody of Tommy but losing her grip, turns to Dunn for a fix. Van Alden's enlisted by Frank and Al Capone to bust some Democrat supporters' heads; Frank's gunned down by deputized Chicago agents. Nucky has Willy stick to a false alibi, pays off the Philadelphia DA to free him, and leaves him with some avuncular advice shortly before Willy's roommate is arrested for Gaines' death. Eddie, back at the Albatross and guilt-ridden about betraying Nucky's trust, jumps out of his window to his death.

Rothstein runs into Margaret at her work, which is not entirely above-board. Dunn deals with the church's concern about his heroin in the community. Willy drops out of college - infuriating his father - and turns to Nucky for work. After Johnny Torrio's arrested in a police raid on a distillery that he just bought from O'Banion, he gives Capone the go-ahead to kill the Irishman. 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.

Despite Tolliver's turning of Eli, Hoover's still uninterested in scotching the bootleggers' network. Nucky is forced into a deal with Narcisse after learning he is Masseria's partner on the heroin pipeline. Nucky promises Chalky to Narcisse but tells Mayor Bader to have cops slip Chalky out of town; too late, though, he discovers through Willy that Bader is in Narcisse's pocket.

Gillian is tricked by Roy, who is actually a Pinkerton agent, into confessing to her killing of Roger.

||Chalky confronts Nucky at gunpoint and demands they get rid of Narcisse. Richard asks Nucky to disclose the location of Jimmy's body to keep Gillian in jail; in return, Nucky employs him for a hit. Richard sends Julia, Tommy, and Paul to his sister's. Nucky tells Narcisse that Chalky wants to meet. After an attempt on Torrio narrowly fails, he hands over his entire operation to Capone. Knox/Tolliver sets up an eavesdrop for the big meeting but no one shows; Eli's called to the Albatross, where Nucky puts a gun to his head until Willy intervenes. Tolliver confronts Eli in his home; they fight and Eli beats him to death. Chalky meets Narcisse at the Onyx but his bluff of providing Daughter's whereabouts is met by Narcisse's revelation that he has his daughter Maybelle. From his sniper position, Richard hesitates long enough that, when he pulls the trigger, Maybelle has moved to the table and into the shot; she is killed and Richard is mortally wounded by one of Narcisse's men. Narcisse is arrested and turned by Hoover into an informant on Marcus Garvey. Chalky retreats to Havre de Grace. Nucky sends Eli off to Chicago, where he is met by Van Alden. Richard, imagining his reunion with his new family in Wisconsin, dies peacefully under the pier.
