Boardwalk Empire: Atlantic City Treasurer James Neary’s Arrest Warrant from Episode 105

James Neary does not explicitly turn on Nucky Thompson in Boardwalk Empire —

• In Season 1, Episode 5 ("Nights in Ballygran"), Neary is arrested by Agent Van Alden during a Prohibition raid.
• Although Van Alden attempts to use pressure tactics to flip members of Nucky’s inner circle, Neary remains loyal (or at least silent) and doesn’t directly cooperate with the Feds.
• He fades into the background after this. His role diminishes, and he’s not a key player in the later episodes. He’s mentioned a few times, but he never resurfaces as a major threat or informant.

So while the arrest puts pressure on Nucky's operation, Neary doesn't end up betraying him — it's more of a "loyal machine man goes down quietly" situation. This item comes with a certificate of authenticity.
