Soon after inheriting her family's stately home, eccentric artist Fenella Harford discovers a stash of hidden diaries and enlists a young academic, Marva, to confirm their authenticity.

A gripping gothic psychological thriller, The Authenticator reunites writer Winsome Pinnock ("Leave Taking") with director Miranda Cromwell ("Death of a Salesman") following their acclaimed production, "Rockets and Blue Lights".
