Meeting at Wodehouse's bedsit in London in 1903, Westbrook, a teacher of Latin and Greek at Emsworth House, a prep school in Emsworth, near Portsmouth, would invite Wodehouse to come down and stay with him. The school was run by Baldwin King-Hall, to whom Wodehouse would write the dedication in Indiscretions of Archie, published in 1921. In 1912, Westbrook married Ella, Baldwin King-Hall’s sister, with whom Westbrook and Wodehouse had written an unsuccessful "musical sketch", The Bandit’s Daughter, which only played for a few days at the Bedford Theatre in Camden Town in 1907. Shortly after their marriage, Ella set up a literary agency and became, until her retirement in 1935, Wodehouse’s literary agent for his contracts in the UK.
