"Our man in Havana"; the story so far.

Reading the fourth part of the book, was really rough, this week. I can tell that it has been difficult for me from the beginning, also. It can be true, and moreover real, that studying english this term hasn´t been easy for me. I have too much work at school, and less time and energy to do homework. Despite all this, I am trying to do my best, even when it is friday and I couldn´t be able to finish the reading nor updating my blog.
Other thing that has been given me a hard time is the fact that this story is always flowing between fantasy and reallity; it has been hard for me to know when something is false or real.
However, all the things that I just mentioned, were good for me for one reason: "The greater the struggle, the better the result". Sometimes, one needs difficulties, to be capable, to get stronger.
Okay, no more thoughts.
I will try to do a summary of the fouth part, of what I have understand.
Beatrice and Mr. Wormold were out; they went for a walk. When they came back, Milly told them about something that happened out on the street, something like a revolution: someone had tried to assasinate someone, but she really couldn´t know whose were involved. Milly thinks that Dr. Cifuentes is the one who has been killed, and, even though she doesn´t know him, she feels pity for him. It is late at night, and Mr. Wormold sends Milly to sleep, so Beatrice and him can do some work.
Beatrice thinks that this assassination is a warning for them about the roughness of "them", "the others"; she really believes that there are other Wormold´s agents, and that they have to warn Professor Sanchez and Teresa, and also to tell them to hide for a while, until it is safe.
They go to the Shangai, a streaptease show, because Beatrice wants to meet Teresa, the nude dancer. Mr, Wormold has to do an extra effort to convince Beatrice that Teresa is not there; but, there appears one girl called Teresa, by coincidence; therefore, they try to convince her about the danger situation, that her life is under risk. They finnally convince her to go to Cienfuegos with them.
They get to Vedado, a very luxurious place, with white houses owned by millionaire people. There, they are going to find professor Sanchez´s house. They enter the professor house and find him with his mistress; the woman thinks that they are spies; she believes that Maria, the professors wife, has send Beatrice and Mr Wormold to sneak on them. But professor Sanchez thinks that they only came to make trouble, so he calls the police. Thus here arises captain Segura responding the call from professor Sanchez "about a man who had broken into his house with vague threats"; they think that this is an intruder who has come to steel the valuable pictures that professor Sanchez owns.
After the investigation, captain Segura realizes that everything is in order and warns Mr. Wormold about professor Sanchez´s wife, and tells him not to get mixed up with her, and to stay away from naked women.
Captain Segura invites Mr. Wormold to play checkers, and using the movements on the board, he notifies Mr. Wormold that he knows everything about Dr. Hasselbacher, and their friendship. Furthermore, that he doesn´t trust Dr. Hasselbacher.
Mr. Wormold got to Dr. Hasselbacher´s appartment, and found him dressed up with an ancient uniform. Dr Hasselbacher tells that he only wears that uniform when he feels guilty about a man´s death,  Raul´s death. Mr. Wormold reminds him that everything and everyone, the platforms and the agents, had been invented, as a trick to convince the MI6 that he is a good spy, and that he is doing his work in Havana.
Meanwhile, in London, the chief and his guests are talking about a double agent; somebody they have inside the police office in Havana, someone who is using a game called checkers as an excuse to contact with "each other". Would they be talking about Captain Segura and Mr. Wormold? We'll have to wait and see what happens next week...
