"But cannot your brother explain how he lost this button at Caffie's?"
"Certainly, and in the most natural way. He went to see Caffie, to ask him for a letter of recommendation, saying that he had been his clerk for several years. Caffie gave it to him, and then, in the course of conversation, Caffie spoke of a bundle of papers that he could not find. Florentin had had charge of these papers, and had placed them on a high shelf in the closet. As Caffie could not find them, and wanted them, Florentin brought a small ladder, and, mounting it, found them. He was about to descend the ladder, when he made a misstep, and in trying to save himself, one of the buttons of his trousers was pulled off."
"And he did not pick it up?"
"He did not even notice it at first. But later, in the street, seeing one leg of his trousers longer than the other, he thought of the ladder, and found that he had lost a button. He would not return to Caffie's to look for it, of course."
"Of course."
"How could he foresee that Caffie would be assassinated? That the crime would be so skilfully planned and executed that the criminal would escape? That two days later the police would find a button on which they would build a story that would make him the criminal? Florentin had not thought of all that."
"That is understood."
"The same evening he replaced the button by another, and it was only on reading the newspaper that he felt there might be something serious in this apparently insignificant fact. And we shared his alarm."
"Have you spoken to any one of this button?"
"Certainly not; we know too much. I tell you of it because I tell you everything; and if we are menaced, we have no help to expect, except from you. Florentin is a good boy, but he is weak and foolish. Mamma is like him in more than one respect, and as for me, although I am more resistant, I confess that, in the face of the law and the police, I should easily lose my head, like children who begin to scream when they are left in the dark. Is not the law, when you know nothing of it, a night of trouble, full of horrors, and peopled with phantoms?"
