She struggled to find a footing in the theatre after she graduated from RADA with a bronze medal since she lacked the conventional good looks which were then an absolute requisite for actresses in dramatic roles. After touring in minor parts with Ben Greet's Shakespeare company she may have played small parts for two seasons in the new repertory company at Oxford, but her contract was not renewed. She was told that they required a prettier actress. Unable to secure any acting engagements, she gave up the stage at the age of 23, and she took up work as a welfare officer in the Shredded Wheat factory in Welwyn Garden City. Tyrone Guthrie, due to direct a season at the new Festival Theatre, Cambridge, asked her to join his company. Her performance as the stepdaughter in Pirandello's Six Characters in Search of an Author made her the theatrical talk of Cambridge. She followed with Isabella in Measure for Measure with Robert Donat, Pirandello's Naked, the title role in Iphigenia in Tauris, Varya in The Cherry Orchard, and Rebecca West in Henrik Ibsen's Rosmersholm.
