What if anyone in Hell could take a bus trip to Heaven and stay there forever if they wanted to? In "The Great Divorce" C. S. Lewis again employs his formidable talent for fable and allegory. The writer finds himself in Hell boarding a bus bound for Heaven. The amazing opportunity is that anyone who wants to stay in Heaven, can. This is the starting point for an extraordinary meditation upon good and evil, grace and judgment. Lewis's revolutionary idea is the discovery that the gates of Hell are locked from the inside. In Lewis's own words, "If we insist on keeping Hell (or even earth) we shall not see Heaven: if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell."
