Marjorie is Brenda Last’s younger sister. Though lovely as well, she is “more solid than Brenda.” She and her husband Allan are popular but not rich, and they live in a small house in London. Brenda normally stays with them when she comes to town, until she gets her own flat. Marjorie consistently disapproves of Brenda’s affair with the odious John Beaver, though she is almost alone among London socialites in doing so.
