Scene Six is in St John's Wood where Magdalen has lodgings. Estranged from Norah and from Miss Garth, who she thinks betrayed her husband's whereabouts to Lecount, she conceives a plot to disguise herself as a parlour maid and infiltrate Admiral Bartram's house in order to search for the Secret Trust document. Her own maid, Louisa, trains her for this role in return for Magdalen's giving her the money to marry her fiance, the father of her illegitimate child, and emigrate to Australia.
