What are Paul's two favorite books in How Steel was Tempered?
The gadfly and Spartacus asked, Tell me about these two books. Answer: On a hot evening in June, Arthur Bolton, a college student, was leafing through a large stack of sermons in the library of Pisa Theological Seminary. Father Montanelli, the dean, looked at him affectionately. Arthur was born in Bolton's home, a wealthy Italian-English businessman. He was nominally born to Bolton and his stepwife, but in fact he was the illegitimate child of his stepwife and Montanelli. Arthur was discriminated against by his half-brother and sister-in-law at home since he was a child. He was very unhappy to see his mother tortured and insulted by them, but he never knew the truth. Arthur respects Father Montanelli's profound knowledge, regards him as a mentor and friend, and returns Montanelli's care for himself with a sincere heart. At that time, Italy was being invaded by Austria, and the idea of Italian youth party fighting for national independence attracted enthusiastic young people. Arthur decided to devote himself to this cause. Montanelli was very upset after discovering Arthur's activities and tried to dissuade him; But Arthur felt that there was no contradiction between being a devout believer and a man fighting for Italian independence. At a secret meeting, Arthur met his teenage girlfriend Joan Ma and fell in love with her quietly. Montanelli was transferred to Rome as bishop, and the police spy Cuddy became the new priest. Under his deception, Arthur revealed their actions and the names of his comrades in the confession, so he was arrested and imprisoned with his comrades. When they were arrested, even Qiongma thought Arthur tipped them off and slapped him in the face. Arthur hated his naivety and ignorance, and was shocked that the priest would betray him. At the same time, he learned that Father Montanelli turned out to be his real father, and his most admired person cheated him. This series of blows caused him to fall into extreme pain and almost go crazy. He broke his beloved Jesus cross with a hammer to show his break with the church. Then he disguised the scene of suicide and went into exile in South America alone. In South America, Arthur spent 13 years in a hell on earth. Wandering life tempered Arthur. When he returned to Italy, he was already a strong, cold and sophisticated "gadfly". The Ma Zhini Party ordered him to expose the fraud of the church. He hit the nail on the head with a pungent pen and pointed out that the liberals headed by Cardinal Montanelli are actually faithful running dogs of the Vatican. The gadfly won everyone's love. At this time, he met Qiongma again, but Qiongma didn't recognize him. The gadfly and his comrades are actively preparing for the uprising. Suddenly surrounded by the enemy in an arms smuggling operation, the gadfly covered others to break through, but he hung up his gun because of Montanelli's sudden appearance and was unfortunately arrested. The gadfly's comrades tried to rescue him, but the gadfly was seriously injured and fainted on the way out of prison. The enemy decided to execute him quickly. Montanelli, who came to visit, tried to persuade him to surrender on the condition that his father and son gave up the bishop; The gadfly told his tragic experience emotionally, trying to impress Montanelli and let him choose between God (religion) and his son (revolution). But none of them can give up their faith. Montanelli signed the death sentence of the gadfly, and he went crazy in pain. On the execution ground, the gadfly took his time and died generously. In a letter to Qiongma in prison, he wrote a poem that they were familiar with when they were young: Whether I am alive or dead, I am a bird. Happy flies! At this time, Joan Ma suddenly realized that the gadfly was Arthur she had loved and wronged.
