I opened my mouth but he forestalled me.

"Before you ask, I will add that the corpse had obviously been in the water for some days and I spent the previous three weeks in Milan. I was part of a senatorial delegation to the duke; we returned the previous day, so there is no possibility that I killed her. Furthermore, yes I did recognize the amber brooch. I saw it four or five years ago, on a woman whose name I do not recall and have no wish to be informed of now."

His beard bristled aggressively. His squeak rose a fifth. "She was a whore and I have no doubt your so-called servant is another. If you are truly a nobile homo, then I suggest you spend more money on clothes and less on servant girls. Go back to San Barnaba and stop pestering your betters."

San Barnaba is indeed the parish of my birth, but his remark was only a taunt, not a spectacular guess, because it is also home to many of the impoverished nobility, the barnabotti.

I bowed low. "I thank you for a very succinct statement, Your Excellency."

The manservant still stood by the door. He opened it and I left.

As I trotted downstairs, I mused that what a successful politician in Venice needs, apart from the accident of noble bloodlines, is oceans of money, a large family, and a strong speaking voice, in that order. Avonal seemed to have none of those and yet he was already in the Senate. He seemed to be an honest man, but I doubted that this was the secret of his success.

I insisted then that we let Giorgio go home to his brood and Violetta and I celebrate Carnival, for dusk was falling. If the Maestro's orders to be back by curfew had been intended seriously, he should have known better.

Donning masks, we went off to celebrate Carnival, dancing and drinking, laughing and eating by the light of bonfires. We cheered the fireworks and booed at a bullbaiting, while all around us swirled bishops and abbesses, duchesses and clowns. It was an enchanting evening, and the crowning episode, as provided by Helen, was beyond compare. It was well after midnight before I hammered Ca' Barbolano's door knocker to waken Luigi, the archaic night watchman.

When I let myself into the apartment I saw light under the Maestro's door, so I peeked in. He was leaning back on a pile of pillows, reading-and still awake, which was not surprising for he sleeps little at the best of times and even less lately. He reads so much by artificial light that I cannot understand why he hasn't long since gone totally blind. Scowl and nightcap, sheets and book, together formed a puddle of lamplight in the darkness as if an apprentice artist had been practicing chiaroscuro.

"Need anything?" I inquired helpfully.

"No. Learn anything?"

"I met an honest senator."

"Incredible!"

"We thought so." I summarized our afternoon. "Lucia was expecting an old friend and went off in a public gondola with an unidentified man. I did not talk with the women who last saw her, because Violetta had already done that. A week later her body turned up in the lagoon. It took a couple more weeks to establish her identity and inform her friends, and if she hadn't been found by an unusually public-spirited person, no one would ever have known what happened to her. I agree that the case seems hopeless."

Nostradamus nodded with satisfaction that the minor mystery of the valuables had been disposed of and the murder case looked so impossible that he need not be tempted by the reward. Then I told him about the second summons and my visit to Palazzo Gradenigo. His face darkened. He loves all mysteries except those he cannot hope to solve and Giovanni Gradenigo might have taken his secret to the grave.

"I could hardly push myself into a house of mourning when the old man was still warm," I concluded. "But first thing tomorrow, I go to find Battista."

"Not first thing. It will wait. I have letters to be encrypted."

"His master has died. He may well be out of a job and gone. He may be gone already."

The sage had not thought of that, so I won that round.

Normally I snap awake just before the marangona bell in the Piazza announces sunrise. That day I heard it as I was walking-or possibly sleepwalking-across the Campo San Polo, heading for the Palazzo Gradenigo. I had not bothered to disturb Giorgio, hoping that some exercise would clear my sleep-deprived wits. Already workers were hurrying to work, many darting into the churches for a hasty prayer. It was a fine day for early February, promising a timely spring.

At that dewitching hour I did not expect to run into any of the Gradenigo family and even their senior servants might snatch a little extra time on the pillow. A manservant should be an early riser, though, and perhaps an unemployed manservant facing the need to find a new employer would have worried himself awake. I found the rear entrance, a gate into the yard, and to my delight it was already unlocked. Routine in the palazzo was still in disarray, or seemed to be so, for no one argued when I appeared at the servants' door and announced that it was urgent that I speak to Battista-I did not even have to invent some tale about being sent by the morticians or the attorneys. I made myself as comfortable as possible on a stone bench in the yard and shivered in patient silence.

In a few minutes a man emerged from the house and hurried over to tell me that he was Battista da Schio. Servants rarely possess family names, and normally have no need of them, anyway. They are often immigrants from the mainland, and for legal purposes are then identified by their birthplace. He was around fifty, a brown-gray sort of person smaller than me, looking as if he might have been chosen for timidity and mousiness.

"Sit down," I said cheerfully, which he did distrustfully. "I'm Alfeo, assistant to Doctor Nostradamus."

To my surprise, he turned chalk white. His fright was so obvious that I could not ignore it.

"There's no need to be alarmed. I apologize… The doctor apologizes for misunderstanding your message and not sending me over right away. As I wrote… You did receive the reply I sent?"

Battista shook his head and seemed to grow smaller still. I began to understand.

"Did sier Giovanni tell you to write to Nostradamus?"

Shake again. The man had lost his tongue.

"Then tell me why you did, please. I will keep your secret if you have one, I promise."

His tongue returned and played with his lips for a moment. "The master kept asking for…" His voice was very soft and hesitant. "… for someone to send for Nostradamus. He was a kind master and he was dying and no one was doing what he said." Taking encouragement from my nods, he went on, a little more sure of himself. "I was attending him all the time. He needed… a lot…"

"How did he die?"

"He bled to death, kept vomiting blood. It started about four days ago and was getting worse. The doctors… He sent the doctors away."

"Wise of him." Hematemesis is not the worst way to die, but not the best or most dignified, either. The most likely cause was a tumor in the stomach. "Was he in much pain?"

"He never said he was, not to me. But I never remember him complaining about anything."

"So you were attending him, cleaning up, changing sheets. Horrible job! I hope they paid you extra?"

He shook his head and avoided my eye.

"So who else was there?"

"Friends, family. They'd been coming to say good-bye ever since the doctors told him to send for a priest."

I could imagine the scene: The dying man struggling to say his farewells to all the visitors, fighting against nausea, probably also pain and the gross indignity of puking out his own lifeblood. And Battista creeping around like an ant between all the grandees.
