I read Agatha Christie's Autobiography.  It was kind of interesting the way she described when she was a teenager hearing and reading that Archduke Franz Ferdinand had been assassinated and nobody thought much of it. Days passed and they read about the development, still without too much concern. It took precisely one month for WWI to begin - from the Archduke's assassination on June 28 to Austria-Hungary declaring war on Serbia on July 28, 1914.
