J. M. Barrie wrote the four-act drama What Every Woman Knows. At the
Duke of York's Theatre in London, showman Charles Frohman gave it its
debut performance. Maggie Wylies, a plain young woman who they worry
will stay a spinster, is the daughter of a wealthy but ignorant Scottish
family. The Wylies learn one night that John Shand, a responsible young
university student, has been breaking into their house to read books
from their extensive collection. Shand is indigent and unable to afford
to purchase the textbooks he needs for law school. Maggie Wylie and John
Shand agree: if he agrees to marry her after five years, her family
would pay for his schooling. Maggie utilizes her skills and contacts to
quietly work behind the scenes to help John win the election after
realizing her husband's desire to become a member of parliament. She
keeps advancing his career without ever letting him realize that she is
the driving force behind his success. In the end, he marries Lady Sybil
Lazenby, a young Englishwoman who is stunning, elegant, and well-born.
