Girolamo started. "On the border-land of Rome!" he echoed. "This mission of thine is then weighty; and thou fearest——"

"Nay, I fear naught," said Piero haughtily. "But the times are perilous; and later, if thou would'st seek me, thou hast the clew. But of the mission, to which I am sworn in secrecy, let it not be known that I have so much as named it—it would argue ill for me and thee. And the clew is for thy using only. Meanwhile, forget that I have spoken. The Ave Maria will soon waken the fishers of Murano. Addio!"

But he still waited as if he had not uttered all his mind. Girolamo studied his face closely.

"There is more," he said. "Speak!"

"By the Holy Madonna of San Donato!" said Piero, casting off his restraint with a sudden impulse, "if I come not back, I would have thee know that if ever there came a chance to me to serve Marina—the Lady Marina of the Giustiniani—I, Piero, barcariol or gastaldo, would serve her as a soldier may serve a saint. For she hath been good to the Zuanino. Ay, though it cost me my life, I would serve her like a saint in heaven!" he repeated. Then, flushed with the shame of such unwonted speech and confession, he hastened to the door, and his steps were already resounding on the stone floor of the passage when Girolamo recovered from his astonishment sufficiently to follow him into the shadow and command him to stop.

"Thou hast seen my daughter—thou hast news of her?"

"Ay, yestere'en, at the Ave Maria, I spoke with her, in Santa Maria dell' Orto, coming upon her kneeling before the great picture of Jacopo Robusti—she, saint enough already to wear a gloria and looking as if the heart of her were worn away from grief! She hath need of thee daily, for her love for thee is great, and death not far."

"Tell it plainly!" commanded Girolamo, hastening after the retreating figure and violently grasping his arm to detain him. "Have I failed to her in aught? She is soul of my soul! Maledetto! why dost thou break my heart?"

"Look to thine other son-in-law!" Piero retorted wrathfully; "him of the crimson robe who sits in the Councils of Venice, and findeth no cure for thy daughter—dying of terror beside him."

"It is a base slander!" cried old Girolamo, trembling with anger and fear. "Never was wife more beloved and petted! Marcantonio hath no thought, save for Marina and Venice!"
