Sir Joseph and Lady Webbing are the foster parents of Marie-Louise. The couple are also in league with Verrinder, a German spy. When their work against England is discovered, they commit suicide. Marie-Louise, who has been an unwitting part of their schemes, is allowed to go to the U.S. if she promises to keep everything a secret.
