Quote: "The best time to plan a book is while you’re doing the dishes."
Bottom line: Agatha Christie’s mother didn’t allow her to go to school because she thought it would harm her mind. However, her mother did encourage Agatha to write.
Her first book was published in 1920, a murder mystery introducing the character Hercule Poirot, who appeared in many of Christie’s books. She also created a series featuring an amateur spinster detective, Miss Marple.
Christie took an oath promising to never keep vital clues from her readers and never to use invented poisons as a crutch.
