William moves Sugar into her own apartments,where she continues to write and advise him on the running of the factory. Whilst he is in Glasgow on business,she goes alone to the opera,where she meets Agnes and comforts her after one of her fits,arranging to send her home. Agnes calls her her 'guardian angel'. Henry visits Mrs. Fox,who is ill with,according to Dr. Curlew,terminal consumption so he carries on her work helping prostitutes. He meets Sugar's friend Caroline,who prefers to stay on the game with all its risks than take a lower paid factory job. William tells his brother to satisfy Mrs. Fox sexually but Henry has a fatal mishap during a sexual fantasy in which the flames of passion are only too literal. Sugar suggests to William that she becomes a tutor to his little daughter Sophie.
