Trivia

 * During the air raids in WWII, Lewis took care of three children who came to stay at his house. This experience inspired him to write the Chronicles of Narnia, and one of those girls was called Margaret.
 * The three are only mentioned once, on the first page of The Lion, the Witch, and the Wardrobe.
