1. Her mother, Clara Miller: Agatha Christie often credited her mother for her love of storytelling. Clara Miller was a gifted storyteller and instilled in her daughter a love of words and imagination. She would read to Agatha and her sister as children, often inventing stories and characters. This early exposure to storytelling is often cited as a major inspiration for Agatha Christie's later writing.
2. Her sister, Madge Miller: Although less directly acknowledged than her mother, Madge Miller also played a significant role. She was a talented artist and illustrator, and together with Agatha, they created elaborate stories and worlds. Their collaboration nurtured Agatha's imagination and helped her develop her storytelling skills.
However, it's important to note that Agatha Christie herself was a voracious reader and a keen observer of human nature. These factors, alongside the influence of her family, undoubtedly contributed to her successful writing career.
