In the 1970s, a single night in a remote hunting lodge with a Hollywood director and his leading lady sparks an international scandal. It wrecks Astrid’s dazzling stage career and destroys her marriage to charismatic Scottish actor Magnus Fellowes. Magnus becomes globally famous, while Astrid retreats to a dilapidated Sussex windmill. Now 82, she lives there still, in eccentric poverty, with her housekeeper turned best friend, Mrs Baker. But Mrs Baker has a dark past too. There is an ‘Awful Incident’ at the windmill; police come knocking. Are these two ‘old ladies’ really as innocent and vulnerable as they seem? Then Astrid learns that Magnus, now on his death bed, is writing a memoir that will expose the glamour and forgotten crimes of her past. Furious, she heads to Scotland, determined to stop him, whatever it takes.
