I Sank Roger Kimball was a memoir by Sylvia Enos (ghostwritten by Ernie) that told the story of how Mrs. Enos avenged her husband, American sailor George Enos, whose ship was illegally sunk by Confederate submersible commander Roger Kimball after the end of the Great War. The book sold briskly throughout the United States, Canada, and Quebec during the 1920s. As one might expect, it did less well in the Confederate States.
