Rumblings of war and social unrest inspire trades union activists to target Selfridge's. Harry responds by throwing a tango party to thank the staff for their hard work. He also wants to do something more public and asks Agnes to organise a Celebration of Empire in the store - but is it too much for her? Meanwhile, Rose secretly seeks out an old friend for Harry, and trouble is brewing for Lady Mae.
