Graham Greene's the Honorary Consul

Dr. Eduardo Plarr is a medical doctor with a Paraguayan deceased mother and an English anti-junta revolutionary father, possibly still alive but imprisoned in Paraguay, who lives in Argentina during the country's so-called Dirty War. He unsuccessfully tries to get news about his father from his Argentinian pro-junta acquaintance Colonel Perez. One night, Eduardo is summoned to attend to the alcoholic British Honorary Consul, Charley Fortnum, who asks to be taken to a brothel, where Eduardo notices a beautiful young prostitute but she leaves with another man. When he later returns to the whorehouse to find her, he learns that the prostitute, Clara, left the place for good. Some time later, Charley calls him to examine his wife, and when Eduard arrives, he sees that Charley's wife is none other than Clara. One day, Eduardo meets her by chance in a store and buys her an expensive pair of sunglasses. Clara goes with him to his apartment and they begin a love affair. When Clara becomes pregnant by Eduardo, Charley believes that the baby is his. Meanwhile Eduardo's childhood friend from Paraguay, Leon, visits him in his office and tells him that his father is still alive in prison in Paraguay. Furthermore, he tells him that he and his rebel friends plans to abduct the American Ambassador and exchange him for several political prisoners in Paraguay including Eduardo's father. However, Leon needs inside information about the ambassador's visit and asks Eduardo to get it from Charley. What will Eduardo do?
