meant some official document giving details of the case you've been charged with investigating, It didn't occur to the Registrar that anyone would be suspicious, Everyone's different, the woman who lives on the ground floor, for example, she doesn't open her door to anyone, I'm different, I like talking to people, Well, I'm very grateful to you for your help, I'm only sorry I can't be of more use to you, On the contrary, you've been a great help, you mentioned the lady downstairs and the matter of the credentials, Well, I'm glad you feel like that about it. The conversation looked set to continue for a few more minutes, but the peace in the house was suddenly interrupted by the crying of a child, who must have woken up, Its your little boy, said Senhor José, It's not a little boy, it's a little girl, I told you before, smiled the woman, and Senhor José smiled too. At that moment, the street door banged and the light on the stairs came on, It's my husband, I recognise the way he comes in the door, whispered the woman, go away and pretend you didn't speak to me. Senhor José did not go down the stairs. Noiselessly, on tiptoe, he went rapidly up to the landing above and stayed there, pressed against the wall, his heart pounding as if he were living through some dangerous adventure, while the young man's firm steps grew louder as they approached. The bell rang, between the opening and shutting of the door he could still hear the baby crying, then a great silence filled the stairwell. After a moment, the light went out. It was only then that Senhor José realised that almost the whole of his dialogue with the woman had taken place in the conspiratorial shadows of the stairway, as if both of them had something to hide, "conspiratorial" was the unexpected word that came into his head, What were we conspiring about, why "conspiratorial," he wondered, the fact is that she hadn't turned the light on again when it went out shortly after they had exchanged their first words. At last, he began to go back down the stairs, cautiously to begin with, then quickly, he paused only for a moment to listen outside the door of the ground-floor apartment, he could hear a sound inside that must be the radio, he decided not to ring the bell, he would leave that new investigation for the weekend, for Saturday or Sunday, but this time he would not be caught out, he would present himself with his credentials in his hand, invested with a formal authority that no one would dare to question. They would be false credentials, of course, but, they would bear the irresistible force of an official stamp and impress, and they would save him the task of having to dispel suspicions before getting down to business. As for the chief's signature, he felt absolutely no qualms, it was hardly likely that the old lady in the ground-floor apartment would ever have seen the Registrar's signature, whose curlicues, when he thought about it, precisely because of their fantastic, ornamental nature, would not prove particularly difficult to imitate. If all went well this time, as it was bound to, he would continue to make use of the document whenever he encountered or foresaw difficulties in future investigations, because he was sure that his search would not end in that ground-floor apartment. Even if the woman had been there when the unknown woman's family had lived in the building, they might not have known each other, in the old lady's weary memory, it might all come down to a few vague recollections, it would depend on how many years had passed since the family on the second floor had moved somewhere else in the city. Or somewhere else in the country or even the world, he thought anxiously, once he was out in the street again. Wherever the famous people in his collection went, they always had a newspaper or a magazine following in their tracks and sniffing around them for just one more photograph, one more question, but nobody wants to know about ordinary people, no one is
