I put it in my pocket, finished my work and started immediately for Milan. I didn't quite know what I meant to do--my head was in a whirl. I saw at once what must have happened. Fernando Briga, then a lad of fifteen or sixteen, had attended his father in prison during Emilio Verna's last hours, and the latter, perhaps aware of the lad's liberal sympathies, had found an opportunity of giving him the letter. But why had Briga given it up to the warder? That was the puzzling question. The docket said: "_Given by_ Doctor Briga's son"--but it might mean "taken from." Fernando might have been seen to receive the letter and might have been searched on leaving the prison. But that would not account for his silence afterward. How was it that, if he knew of the letter, he had never told Emilio's family of it? There was only one explanation. If the letter had been taken from him by force he would have had no reason for concealing its existence; and his silence was clear proof that he had given it up voluntarily, no doubt in the hope of standing well with the authorities. But then he was a traitor and a coward; the patriot of 'forty-eight had begun life as an informer! But does innate character ever change so radically that the lad who has committed a base act at fifteen may grow up into an honorable man? A good man may be corrupted by life, but can the years turn a born sneak into a hero? You may fancy how I answered my own questions....If Briga had been false and cowardly then, was he not sure to be false and cowardly still? In those days there were traitors under every coat, and more than one brave fellow had been sold to the police by his best friend....You will say that Briga's record was unblemished, that he had exposed himself to danger too frequently, had stood by his friends too steadfastly, to permit of a rational doubt of his good faith. So reason might have told me in a calmer moment, but she was not allowed to make herself heard just then. I was young, I was angry, I chose to think I had been unfairly treated, and perhaps at my rival's instigation. It was not unlikely that Briga knew of my love for Donna Candida, and had encouraged her to use it in the good cause. Was she not always at his bidding? My blood boiled at the thought, and reaching Milan in a rage I went straight to Donna Candida.
