She eyed the paper coldly. Her first impulse was to call Fortemani and carry out her threat of having Gonzaga whipped, refusing so much as to see this thing that he so confidently termed a proof; but it may be that his confidence wrought upon her, touching a chord of feminine curiosity. That he was wrong she never doubted; but that he believed himself right she was also assured, and she wondered what this thing might be that had so convinced him. Still she did not touch it, but asked in an indifferent voice:

“What is it?”

“A letter that was brought hither to-night by a man who swam the moat, and whom I have ordered to be detained in the armoury tower. It is from Fanfulla degli Arcipreti to the Count of Aquila. If your memory will bear you back to a certain day at Acquasparta, you may recall that Fanfulla was the name of a very gallant cavalier who addressed this Messer Francesco with marked respect.”

She took that backward mental glance he bade her, and remembered. Then she remembered, too, how that very evening Francesco had said that he was fretting for news of Babbiano, and that when she had asked how he hoped that news could reach him at Roccaleone, Gonzaga had entered before he answered her. Indeed, he had seemed to hesitate upon that answer. A sudden chill encompassed her at that reflection. Oh, it was impossible, absurd! And yet she took the letter from the table. With knit brows she read it, whilst Gonzaga watched her, scarce able to keep the satisfaction from gleaming in his eyes.

She read it slowly, and as she read her face grew deathly pale. When she had finished she stood silent for a long minute, her eyes upon the signature and her mind harking back to what Gonzaga had said, and drawing comparison between that and such things as had been done and uttered, and nowhere did she find the slightest gleam of that discrepancy which so ardently she sought.

It was as if a hand were crushing the heart in her bosom. This man whom she had trusted, this peerless champion of her cause, to be nothing but a self-seeker, an intriguer, who, to advance his own ends, had made a pawn of her. She thought of how for a moment he had held her in his arms and kissed her, and at that her whole soul revolted against the notion that here was no more than treachery.

“It's all a plot against him!” she cried, her cheeks scarlet again. “It's an infamous thing of your devising, Messer Gonzaga, an odious lie!”

“Madonna, the man that brought the letter is still detained. Confront him with Messer Francesco; or apply the question to him, and learn his master's true name and station. As for the rest, if that letter is insufficient proof for you, I beg that you will look back at facts. Why should he lie to you? and say that his name was Francesco Franceschi? Why should he have urged you—against all reason—to remain here, when he brought you news that Gian Maria was advancing? Surely had he but sought to serve you he had better accomplished this by placing his own castle of Aquila at your disposal, and leaving here an empty nest for Gian Maria, as I urged.”

She sank to a chair, a fever in her mind.

“I tell you, Madonna, there is no mistake. What I have said is true. Another three days would he have held Gian Maria here, whilst if you gave him that letter, it is odds he would slip away in the night of to-morrow, that he might be in Babbiano on the third day to take the throne his cousin treats so lightly. Sainted God!” he cried out. “I think this is the most diabolically treacherous plot that ever mind of man conceived and human heartlessness executed.”
