Set in 1909, Mr Selfridge follows a colourful cast of characters whose lives and fortunes are entangled with the founder of the magnificent department store. Harry, his family, friends and staff open up a rich cross section of London life. From the fashionable Mayfair society to the bright lights, grease-paint, glamour and backstage intrigue of London’s theatres; from the business board rooms, private poker games and smoky jazz halls to the back-street cafes of the working men and women, this is a big city story at the dawn of the modern age.
