The show's executive producer, Kate Lewis, also spilled the beans on scenes with Harry Selfridge, whose life is about to change.
She explained: "We have some surprises in store for the audience in the third series.
"You only have to walk down Oxford Street today to know that Selfridge's department store continued to be successful.
"But for its founder, Harry Selfridge, things were very different. His story was a roller-coaster ride that ended rather tragically."
She added: "We pick up series three in 1919 - the point at which his life really begins to unravel."
