I am a C. S. Lewis fanatic. I’ve read all his works, been to his home in England, and even written a book about one of his stories. For an expert, it can be humbling when an amateur points out something you’ve missed. The book was The Lion, the Witch and the Wardrobe, the first of Lewis’s classic Chronicles of Narnia. The hidden lesson was pointed out by my father-in-law who saw it the first time he read the book. That lesson still speaks to us today.
