‘…the human mind is very surprising and can do terrible things to achieve those most secret and perverse instincts, which are guided by ambitions and power…’
One morning, Robert Langdon, who was a professor of religious iconology at Harvard University, received a call and a fax from Kohler Maximilian, who was the head of the CRN. In the fax there appears the was a picture of a man who had, engraved on his chest, a the seal of the  ancient, religious, missing, anti-christian sect , the illuminati. Langdon took a plane to the headquarters of CRN. There he discovered, along with Kohler and the daughter of  an important scientist’s daughter who had recently died, that someone had stolen ‘antimatter’ (an important and dangerous substance). Through the thief, they discovered that antimatter iswas in the Vatican City  any city of the Vatican. So, Robert and the scientist’s daughter, who was Victoria Vetra, travelled to the Vatican. There, they discovered that a murderer had kidnapped four cardinals, whose would have  been in the conclave which was to be held a few hours later because the pope had recently died. The murderer called a television reporter to broadcast live the first execution of the four cardinals,  which would take place    that would be held in one of the altars of science. Langdon's research led him to the Pantheon in Rome, but after watching a while, he realized that this was not the right place. They went to a church but it was too late. The cardinal was buried to the waist in one of the underground galleries of the church, and was  has been drowned suffocated with  by putting sand in this mouth. On his chest it another ambirgram, one which  that represented the earth, was engraved. So, the murderer continued with their his crimes, killing the remaining three cardinals, but he killed them leaving different tracks to for Langdon, so he managed to find the antimatter. Finally, Langdon and Victoria discovered the reasons of  behind  the murders, which were about the result of a big secret at the Vatican. The pope had had an affair with a nun and of  that meeting was born a child. The nun was killed and the pope raised the child, making him a camerlengo. So, the camerlengo was the murderer, who had killed the pope and the three 4?  cardinals. In addition, he had stolen the antimatter to find himself and for which  people admired him as a hero, to  and be chosen as the new pope. But Langdon settled the case and told the conclave. Then, the truth was discovered. The camerlengo felt cornered and decided to bur ?  alive.

Hi, here's a first correction, it could probably do with someone else helping too because your text has quite specific vocab. Good luck!
