Agatha Christie's The Witness for the Prosecution

1920s London. A murder, brutal and bloodthirsty, has stained the plush carpets of a handsome London townhouse. The victim is the glamorous and rich Emily French. All the evidence points to Leonard Vole, a young chancer to whom the heiress left her vast fortune and who ruthlessly took her life. At least, this is the story that Emily's dedicated housekeeper Janet Mackenzie stands by in court.
