What Every Woman Knows by James Barrie is a witty and insightful play that examines the dynamics of marriage, ambition, and the subtle power of women. The story follows Maggie Wylie, an intelligent but unassuming woman, who marries John Shand, a determined and ambitious young politician. While John believes his success is solely his own, Maggie’s quiet influence and wisdom play a crucial role in shaping his achievements. The play explores themes of love, partnership, and the often-unacknowledged contributions of women. Readers and audiences cherish its humour, sharp social commentary, and Barrie’s celebration of intellect and emotional depth in relationships.
