Part five, chapters 1 and 2.

This part was confussing. However, I will try to do my best to do the summary.
Wormold and Segura met at the Havana Club. I don´t know why, but they seem to know what each of them are doing. They are playing checkers and, meanwhile, talking about their activities in Havana. Captain Segura is asking Mr. Wormold about his trips to other cities, and Wormold tells him that he was visiting his retailers. All the conversation flows between them trying to convince each other about things that they don´t really do, or, do they?: about the agents that Mr. Wormold has recruited, the kind of tortures in wich Captain Segura is an expert, the people who deserve to be tortured, etc.
When they left the club, Wormold met Beatrice and told her that Segura is one of them, and that he is really helping them; Segura is making a list of the foreign agents in Havana, the "wild ducks", that is what Segura calls them. Wormold also convinced Beatrice that he has another secret agent: the blind beggar who sits on the steps outside the Cathedral. He told Beatrice that the agent is not really blind, that his name is Miguel, and that he watches everything that is going on, specially when Wormold mets Segura, as a precaution.
When they got home, Wormold found an invitation for him to make a speech at the European Trader´s Association; he tells Milly that he doesn´t know what he is going to say on that speech.  When he went to his bedroom, he deciphered the cable form the agency, where they told him to flight to Kingston to have a meeting with Hawthorne.
Wormold traveled to Kingston. Hawthorne told Wormold that he asked  him to come because there was something of trouble with the "constructions", and with the photographs that he should have taken and delivered to the agency. They don´t wan´t only the drawings that he sent, because they are a "bit confusing".
Hawthorne also told Mr.Wormold about a conspiracy to kill him by poissoning, at the European Trader´s Association. Hawthorne encourages Wormold to go to the lunch unless he wants "the others" to start misstrusting.
During the flight back to Havana, Wormold met William Carter, a vacuum cleaner´s salesman, who gave him his card. He works at Nucleaners Ltd. At the Customs in Havana, there was Beatrice, waiting for him. She asked Wormold about the meeting in Kinston, and he said that they seemed pleased with him at the agency. He told Beatrice that Hawthorne wanted him to go to the lunch at the E.T.A. to protect his source.
I haven´t noticed, but, when I wrote down the initials in order to not having to write the hall name of the European...There were this!!! E.T.A., what are they trying to tell us? let´s wait and see in the next chapters...
