Mr Selfridge ITV, 9pm
The period drama returns for a fourth and final run, set nine years after the last series. It finds Harry Selfridge at the apex of his power, a retail giant in the roaring twenties. Rumours of his latest romantic dalliances are the talk of the social circuit at Victor Colleano’s decadent new nightspot. Meanwhile, at the store, Harry is set to unveil the “Queen of Time”, a specially commissioned clock at the front of the store. However, before the major unveiling, there’s a danger that newspaper magnate Lord Wynnstay might run some damaging stories about Selfridge’s family.
