"Stay, Signor Barone, one minute. This is an important point; you say that this Paolina saw her lover with La Bianca. How do you know that? and how did it come about?" "Ludovico just told me so; and the girl, it seems, herself told him. Her story is that she went out to St. Apollinare at an early hour this morning to look after a scaffolding or some preparation of some kind that had been made for her to copy some of the mosaics in the church; and that from a window of the church, being on the scaffolding, she saw Ludovico and La Bianca driving by in a bagarino. Now all this probably is true enough. The question is, What did she do then, when she saw what was so well calculated to throw her into a frenzy of jealousy? My theory is, that she followed them into the forest, dogged their steps, and finding her opportunity at the unlucky moment when Ludovico left Bianca sleeping, did the murder there and then." The old lawyer started up from his seat, and thrusting his hands into the pockets of his trousers took a hasty turn across the room; and then resuming his seat, tossed off a glass of wine before making any reply. "And a very good theory too, Signor Barone. I make you my compliment on it," he said at last. "I was not aware of all the facts, the very, important facts, you mention. I had ascertained that this Venetian girl left the city by the Porta Nuova at a strangely early hour this morning; and that was enough already, to fix my eye upon her. But what you now tell me is much more important; advances the case against her to a far more serious point. Upon my word," continued the lawyer, after a pause for further meditation; "upon my word I begin to think that it is the most likely view of the case that this Signorina Paolina Foscarelli has been the assassin. At all events it seems quite as likely a theory as that the Marchese should have done it. Fully as likely," added the lawyer, rubbing his hands cheerily; "the motive, as motives to such deeds go, is quite as great in her case as in his. Greater, or at least more probable! Jealousy has moved to such acts more frequently than mere considerations of interest." "To be sure it has," cried Manutoli; "I think that the circumstances bear more conclusively against her than against him; I do, upon my life." "If only something do not turn up to show that it could not have been done by her, I think--I do think that we have got all that is absolutely necessary for us. For observe, Signor Barone, it is not necessary that she should be convicted. If there is such a probability that she may have been the criminal as to make it impossible to say that it is far more likely that one of the parties suspected should be guilty than the other, there can be no conviction, and our friend is safe." "But I say that all the probabilities are in favour of the hypothesis that she did the deed," cried Manutoli, warmly.
