: Ness reaches out to Brandy LaFrance (Barbara Nichols), the widow of a mobster killed in the pilot, to help trap Guzik.

: The episode concludes with the recovery of Capone's secret financial ledger, which Guzik had hidden in a graveyard. Production & Reception

The episode's title refers to the power vacuum left by Capone's imprisonment. While the "Enforcer" (Bruce Gordon) attempts to seize control through immediate violence, he is challenged by the mob's brilliant bookkeeper, Jake "Greasy Thumb" Guzik (Nehemiah Persoff). Guzik argues for a "legitimate" front to avoid the tax evasion charges that brought down Capone, persuading the syndicate to leave the leader's chair empty for the time being. Key Story Beats
