The historical context of “The Demon Lover” is essential to understanding the story and Mrs. Drover’s emotional state—particularly the complex trauma she might have suffered as a bystander to not one but two world wars: World War I (1914-1918) and World War II (1939-1945).

World War I started with the assassination of the Archduke Franz Ferdinand of Austria-Hungary in 1914. It was one of the deadliest conflicts in human history; the technology and military strategies were so new and unfamiliar that the outcome of any given engagement was difficult to predict. Men who had grown up with horse-drawn carriages suddenly faced modern instruments of war, including gas attacks, machine guns, and artillery bombardment. Participants often expressed their sense that the violence of war baffled explanation. More than 1 million British soldiers were killed or went missing in action. Mrs. Drover is between the ages of 17 to 20 when the war occurs. Her engagement ends with her fiancé’s disappearance during battle.

Of those soldiers who returned, it is estimated that 250,000 or more were diagnosed with “shell shock,” which we would today call post-traumatic stress disorder.
