Neal McDonough will recur as Quarles, a Detroit mobster in a sharp suit who comes to Kentucky with visions of becoming a crimelord. Mykelti Williamson will play Limehouse, a man who lives in a small black town in Harlan County and who will do whatever it takes, legal or otherwise, to protect his holler.
