Lucius Seminole is a Black detective working primarily in Southeast Brooklyn who finds himself entangled in the murder of Frank Minna after Frank dies at a hospital within Seminole’s jurisdiction. Seminole is highly suspicious of Lionel, Julia, and the other Minna Men. Out of his depths in with the Italian mob scene in Brooklyn, Seminole finds himself struggling to force the Minna Men to cooperate with his investigation. Though Seminole pursues answers from Lionel and Tony aggressively in the 24 hours following the murder, once Lionel and Tony begin following their own leads up to Maine, Seminole fades into the background of the investigation.
