No. 44, The Mysterious Stranger can be interpreted as a desperate message to those who are engrossed in distorted religious values ignoring human dignity. If the readers can see through the writer’s thought, they will also know how much Mark Twain had made every effort to make people realize how serious the prejudice and deception rooted deeply in religion are. Even though Twain who had disputed the hypocrisy and unfairness carried out in the name of religion was worried about being criticized harshly, he did not stop speaking out boldly and candidly about irrationality forged from religion. Actually, this novel, which figuratively revealed the atrocities of Karl Lueger who was Hitler's role model, makes people cast doubts on the existence of the God itself as well as religious ethics or morals. Given American society where Christian sentiment was deeply ingrained at that time, it is possible to imagine how much courage he would have needed to write this novel. So, the readers who have grasped the true intention of the writer will not have difficulty understanding the phantasmagoric story structures and the inexplicable dialogues. Thus, today when religious issues are still scattered, this novel like a petition is one of Twain’s greatest masterpieces that must be necessarily read.
