And now, the end is near, and so Elsbeth Season 3 faces its final curtain. Fortunately, it's primed to be a show-stopping finale. After an eventful run full of tyrannical talk show hosts, killer cruciverbalists, and a murderous former model, among other colorful crooks, Carrie Preston is about to enter the glamorous world of cabaret to solve the mystery of a minor royal's death. Welcomed into the most prestigious hotel in all of New York, Elsbeth will brush with faded elegance and rub elbows with old elites, including a legendary cabaret performer who not only calls the storied building her home but fills its halls with her voice. Collider can exclusively share a new, musical sneak peek at the upcoming finale, centering the singer in question, played by Broadway performer Patti LuPone, who has an emotional tune to share.
