4x5 - Mr Selfridge

The ground floor of the department store is transformed into a movie set, as Double Trouble starring the Dolly Sisters and famed-actor Bumby Wallace is filmed. Harry is delighted to be the source of excitement throughout London once again, as Grove and Mardle attempt to grapple with their past - and their future. Kitty comes to a horrible realisation, and Mae reconnects with old-flame Victor. Meanwhile, Harry's mistakes catch up with him in dramatic fashion.
