* Early love of writing: Christie began writing stories as a child, and her imagination was always active. She even wrote a play when she was just 15!
* A creative outlet during World War I: During the war, Christie worked as a nurse in a hospital. She used writing as a way to cope with the stress and boredom of wartime life.
