"Bloody Lady Agatha": The Dark Childhood Imagination that Shaped Agatha Christie's Fiction
An excerpt from Agatha Christie, The Mother of the Cozy Mystery by Nancy West
Agatha was a surprise addition to the Miller family, an “afterthought,” as she would describe herself. Born on September 15, 1890, she was a child of the Victorian fin de siecle (or “end of the century.”) Her siblings, Margaret (“Madge”), born in 1879, and Louis (“Monty”), born in 1880, were eleven and ten, respectively.
Photographed with large hazel eyes and massive golden hair, Agatha was a happy child. Her autobiography, written between 1950 and 1965, recounts how much she relished the pleasures of home: piano lessons; swims in the cove; and afternoon teas of cakes and cream.
Yet beneath the sunshine, a dark imagination lurked. At age five, she began having nightmares of someone she called the “Gunman,” a uniformed Frenchman who carried a musket. Later in her youth, the Gunman would appear in her dreams to be a friend or family member, then suddenly turn into a stranger:
The dream would be quite ordinary….Then suddenly a horrid feeling of uneasiness would come….Sometimes…I would look across at a friend, or a member of the family, and I would suddenly realize that it was not Dorothy…or whoever it might be. The pale blue eyes in the familiar face met mine—under the familiar appearance. It was really the Gunman.
Her imagination developed quickly, enriched by her mother, Clara, and older sister, Madge. Clara invented bedtime stories for Agatha, almost never telling the same story twice.
When home from school, Madge would take her little sister to the theater and regale Agatha with humorous accounts of her friends and activities. Madge also loved performing in and inventing plays, and Agatha would act out roles with her.
At age ten, Agatha wrote her first poem, “The Cowslip.” Around the same time, she invented a story about the noble Lady Madge and bloody Lady Agatha, a Gothic melodrama that involved the inheritance of a castle. It was very short, Agatha would explain, because “both writing and spelling were a pain to me.”
When Clara primly suggested she shouldn’t use the word “bloody,” Agatha protested, “[b]ut she was bloody. She killed a lot of people.” And so emerged Agatha’s first portrait of a serial killer.
