The Ball and the Cross by G. K. Chesterton

Classic novel. According to Wikipedia: Gilbert Keith Chesterton (1874 - 1936) was an influential English writer of the early 20th century. His prolific and diverse output included journalism, philosophy, poetry, biography, Christian apologetics, fantasy and detective fiction. Chesterton has been called the prince of paradox.[1] He wrote in an off-hand, whimsical prose studded with startling formulations. For example: Thieves respect property. They merely wish the property to become their property that they may more perfectly respect it.[2] He is one of the few Christian thinkers who are equally admired and quoted by both liberal and conservative Christians, and indeed by many non-Christians. Chestertons own theological and political views were far too nuanced to fit comfortably under the liberal or conservative banner.
