"A tense, talky, quietly incendiary three-hander about race, legacy and intellectual power that cuts deeper than any jump scare." —Broadway World
Soon after inheriting her family's stately home, eccentric artist Fenella Harford discovers a stash of hidden diaries, and she enlists a young academic, Marva, to confirm their identity.
Joined by Marva's brilliant but overlooked mentor, Abi, the three women come together to seek the truth, soon realising that the secrets at the heart of Harford Hall are darker than they could have imagined.
