I need hardly say that I was very much excited over the strange discovery I had made, as there now appeared to be a reasonable chance of clearing up the mystery of the Palazzo Morone. I had discovered the name of the unhappy young man, which gave me a most important clue to the reading of the enigma; but I had yet to find out the name of the lady who had behaved in such an extraordinary manner and committed so daring a crime. After hearing Peppino's story I fancied that she might perchance be the Contessa Morone, but had later on dismissed this idea as idle, seeing that she had been absent from Verona for many months; but now that Bianca had told me that Pallanza had come straight from Rome, I began to suspect that I had been right in my surmise.
