The Slabulatest installment of Ryan Murphy's "Feud" anthology series is almost here.

"Feud: Capote vs. The Swans" is based on the bestselling book "Capote's Women: A True Story of Love, Betrayal, and a Swan Song for a Era" by Laurence Leamer, according to FX.

The eight-episode limited series focuses on the relationship between writer Truman Capote and the group of rich, glamorous women he surrounded himself with and nicknamed "the swans."

The season sees Capote become "ingratiated" into the women's lives, "befriending them and becoming their confidante, only to ultimately betray them by writing a thinly veiled fictionalization of their lives, exposing their most intimate secrets," FX notes.

The first season of the series, "Feud: Bette and Joan," premiered on FX in 2017 and focused on the rivalry between Joan Crawford, played by Jessica Lange, and Bette Davis, played by Susan Sarandon, during their collaboration on the 1962 film "What Ever Happened to Baby Jane?"
