Thy Soul Shall Bear Witness! (Swedish: Körkarlen) is a 1912 novel by the Swedish author Selma Lagerlöf. It was translated into English by William Frederick Harvey in 1921. Lagerlöf was commissioned to write it by a Swedish association as a means of public education about tuberculosis ("consumption"). It has been dramatized for the screen twice in Sweden and once in France, under various English titles of The Phantom Carriage, The Phantom Chariot, The Stroke of Midnight, and Thy Soul Shall Bear Witness.
