About this show

Marilyn Monroe. John F. Kennedy. Lee Harvey Oswald. Three deaths that shook America. One woman who refused to stop asking questions. New York, 1965. Celebrated journalist and television star Dorothy Kilgallen is chasing the biggest story of her career. America has been given its answers. Dorothy doesn’t believe them. Her investigation leads from Hollywood to the White House, from the Kennedy dynasty to the New Orleans underworld — and towards a web of connections between some of the most powerful and dangerous figures in America. But someone wants Dorothy to stop asking questions. And as the threats move ever closer to home, uncovering the truth could cost her everything. Janie Dee stars as Dorothy Kilgallen in the world premiere of Torben Betts’ gripping new political thriller, directed by Trevor Nunn. What if the stories we know aren’t the whole story? ‍

About Marylebone Theatre

The Marylebone Theatre is an intimate, state-of-the-art venue situated in the heart of central London, just moments from Regent’s Park. Located within the historic Rudolf Steiner House, the theatre offers a refreshing mix of classical, contemporary, and socially-conscious productions, often championing new writing and diverse voices.

Known for its community ethos and innovative programming, the Marylebone Theatre has quickly built a reputation for hosting high-calibre performances across drama, music, and spoken word. With its modern refurbishment and comfortable setting, it is a rising star on London’s independent theatre scene.

The history of Marylebone Theatre

Although the venue itself has existed in various forms within Rudolf Steiner House for decades, the space was fully renovated and relaunched as the Marylebone Theatre in 2022. Since its reopening, the theatre has positioned itself as a hub for new ideas and creative expression, blending traditional performance arts with thought-provoking modern works.

The theatre’s inaugural season included A Sherlock Carol (which has returned to the theatre for every festive season since) and The Dry House by Eugene O’Hare. The theatre hosts a  variety of concerts and off-Broadway transfers, and has established a pattern of quality and ambition that continues to define its programming today.
