Bryony Lavery's new stage adaptation of Angela Carter's story.

When a 17 year old virgin marries a mature and charismatic Marquis it seems like a fairy tale. But when the Marquis is called away on their wedding night, leaving her only her only his keys and a single instruction, her curiosity leads her to uncover a dark secret.

"All is yours, everywhere is open to you, except the lock that the single key fits. You must promise, if you love me, to leave it well alone."
