The Case of the Frightened Lady is a 1940 British, black-and-white, crime, drama, mystery thriller, directed by George King and starring Marius Goring as Lord Lebanon, Helen Haye as Lady Lebanon, Penelope Dudley Ward as Isla Crane, George Merritt as Detective Inspector Tanner, Ronald Shiner as Detective Sergeant Totty and Felix Aylmer as Dr Amersham.

[1] It was produced by Pennant Picture Productions and presented by British Lion Film Corporation.

Goring was an accomplished player whose mother Kate Winifred was a professional pianist who had studied with Clara Schumann.

[8] The New York Times wrote, "the sort of thing Edgar Wallace could make intriguing on paper—or, on the stage, as he did in telling of the horrendous doings at Mark's Priory in Criminal at Large about ten years ago.

But perhaps the real reason is that the story itself is outmoded for cinematic treatment";[9] while Britmovie called it "a tightly written murder mystery...probably one of the best scored films of the 1940s, with the piano dirges being played throughout the movie, “The Case of the Frightened Lady” is a fast moving story... (it) remains a classic for those who enjoy this genre of film";[10] and Vérité noted "a fun and feisty thriller that unlike so many modern films, doesn't outstay its welcome.
