If this acerbic exchange had not taken place, if the presidential manifesto and the other leaflets had, because unnecessary, ended their brief life in the rubbish, the story we are telling would have developed quite differently from this point on. We can't imagine exactly how or in what way, we just know it would have been different. Obviously, any reader who has been paying close attention to the meanderings of the plot, one of those analytical readers who expects a proper explanation for everything, would be sure to ask whether the conversation between the prime minister and the president of the republic was simply added at the last moment to justify such a change of direction, or if it simply had to happen because that was its destiny, from which would spring soon-to-be-revealed consequences, forcing the narrator to set aside the story he was intending to write and to follow the new course that had suddenly appeared on his navigation chart. It is difficult to give such an either-or question an answer likely to satisfy such a reader totally. Unless, of course, the narrator were to be unusually frank and confess that he had never been quite sure how to bring to a successful conclusion this extraordinary tale of a city which, en masse, decided to return blank ballot papers, in which case this violent exchange of words between the prime minister and the president of the republic, which ended so happily, would have been as welcome to him as flowers in May. What other explanation is there for his abrupt abandonment of the complex narrative thread he had been developing merely in order to set off on gratuitous digressions not about what-did-not-happen-but-might-have, but about what-did-happen-but-might-not-have. We are referring, to put it plainly, to the letter which the president of the republic received three days after the helicopters had showered the capital's streets, squares, parks and avenues with the colored leaflets in which the ministry of the interior's writers set out their conclusions about the likely connection between the tragic collective blindness of four years ago and the present-day electoral madness. The signatory was fortunate in that his letter fell into the hands of a particularly scrupulous clerk, the sort who looks at the small print before he starts reading the large, the sort who is capable of discerning amongst the untidy scrawl of words the tiny seed that requires immediate watering, if only to find out what it might grow into. This is what the letter said, Your excellency, Having read, with due and deserved attention, the manifesto addressed by you to the people and, in particular, to the inhabitants of the capital, and being keenly aware both of my duty as a citizen of this country and of the need, during the crisis into which the nation is currently plunged, for every one of us to maintain a close, constant, zealous watch for anything strange that we might see now or might have seen in the past, I wish to bring to the attention of your excellency's renowned powers of judgement a few unknown facts which may help toward a better understanding of the nature of the plague that befell us. I say this because, although I am just an ordinary man, I believe, as you do, that there must be some link between the recent blindness of casting blank ballot papers and that other blindness which, for weeks that none of us will ever forget, made us all outcasts from the world. What I am suggesting, your excellency, is that the first blindness might perhaps help to explain this blindness now, and that both might be explained by the existence, and possibly by the actions, of one person. Before going on, however, impelled as I am by a sense of civic duty upon which I would challenge anyone to cast doubt, I wish to make it clear that I am not an informer or a sneak or a grass, I am simply trying to be of service to my country in the distressing situation in which it currently finds itself, without so much as a lantern with which to illumine the path to salvation. I do not know, how could I, if the letter I am writing will be enough to light that lantern, but I repeat, duty is duty, and at this moment, I see myself as a soldier taking a step forward and presenting myself as a volunteer for a mission, and this mission, your excellency, consists in revealing, and I use the word reveal because this is the first time I have spoken of this matter to anyone, that four years ago, together with my wife, I fell in with a group of people who, like so many others, were struggling desperately to survive. It will seem that I am not telling you anything that you, through your own experiences, do not know already, but what no one knows is that one of the people in our group, the wife of an ophthalmologist, did not go blind, her husband went blind like the rest of us, but she did not. At the time, we made a solemn vow never to speak about the matter, she said that she did not want to be seen afterward as a rare phenomenon, to be subjected to questions and submitted to examinations once we had all recovered our sight, that it would be best just to forget and pretend it had never happened. I have respected that vow until today, but can no longer remain silent. Your excellency, allow me to say that I would feel deeply offended if this letter were seen as a denunciation, although, on the other hand, perhaps it should be seen as such, because, and this is something else you do not know, during that time, a murder was committed by the person I am telling you about, but that is a matter for the courts, I content myself with the thought that I have done my duty as a patriot by drawing your lofty attention to a fact which has, until now, remained a secret and which, once examined, might perhaps produce an explanation for the merciless attack of which the present political system has been the target, this new blindness which, if I may humbly reproduce your excellency's own words, strikes at the very foundations of democracy in a way in which no totalitarian system ever succeeded in doing. Needless to say, sir, I am at your disposal, or at the disposal of whichever institution is charged with carrying out what is clearly a necessary investigation, to amplify, develop and elaborate on the information contained in this letter. I assure you that I feel no animosity toward the person in question, however, what counts above all else is this our nation, which has found in you the most worthy of representatives, that is my one law, the only one I hold to with the serenity of a man who has done his duty. Yours faithfully. There followed the signature and below that, on the left, the signatory's full name, address and telephone number, as well as his identity card number and e-mail address.
