Simon Morris discovers that rare thing in an age of endless sequels and prequels - three stories that simply stand alone. They include a British war story, a French tale of a street-kid turned dressmaker, and a Belgian-Scottish romance about secrets and lies. Operation Mincemeat is the extraordinary true story of a fake spy dropped off to fool the Nazis about the Allied battle plans. Stars Colin Firth, Matthew McFadyen and Kelly McDonald. Haute Couture sees a retiring Dior dressmaker take a stroppy girl from the Paris slums under her wing and teach her the tricks of the trade. Stars Nathalie Baye (Downton Abbey: A new era.) And Nobody has to know sees a Scottish woman lie to a man with amnesia about their relationship. Stars Michelle Fairley (Game of Thrones).
