Vasco would never work that out, but before he rose to the bait, the door swung wide and in marched Bruno, carrying a bundle of firewood that would have flattened me. We have taught him to knock on doors, but he does not understand “audibly,” so it does no good. Beaming at us, he delivered his burden to the hearth, then strode out again, leaving the door open.
“Chilled?” Vasco inquired icily.
“Important business,” the Maestro said. “I must report to the chiefs. You are welcome to accompany us, Vizio. Go and pack up your things. You can be of no further use here.”
Almost no other commoner in Venice would have dared speak to Vasco like that, but he took it from the Ten’s consultant. Glowering at me to indicate that our temporary truce was now ended, he stuffed the latest paper in his satchel and departed.
The Maestro detests having to go out, and I could not recall him ever doing so two days in a row. He must be expecting a handsome reward, in satisfaction, if not in coin. I hurried to my room to don my best. This time I decided to sacrifice good manners on the altar of security, for I knew we were on dangerous business and would be lacking Filiberto’s dubious protection on the way home. I retrieved my rapier and dagger from the top of the wardrobe.
As Giorgio’s strong oar sped us along the Grand Canal toward the Doges’ Palace, I heard the bells of San Giacomo di Rialto tolling sunset.

S o we returned to the palace and the same chamber we had left not twenty-four hours earlier, the Sala dei Tre Capi. The three chiefs themselves must have been rounded up especially to hear our report, for we were kept waiting only a few minutes and Marino Venier still had crumbs in his beard. The Pope himself could not have asked for greater deference than that. Obviously the government was still extremely worried; La Serenissima was anything but serene.
The heat of the day had left the room stifling. The lamps were lit, but their glimmer hardly showed against the remains of daylight. As the Maestro shuffled in, leaning on my shoulder, the chiefs were just settling behind their raised table, and the only aide in sight was Raffaino Sciara, the Grim Reaper in blue. Vasco had left us, gone to report to Missier Grande, no doubt. Sciara placed a chair for the Maestro and retreated to the secretaries’ desk. I saw my master seated, then took my place behind him.
Three old men peered anxiously down at Nostradamus.
Trevisan was in the center. “Well, Doctor? You wasted no time. What news?”
I had never seen the Maestro’s pussycat smile better displayed.
“I have not yet identified your Algol, messere, although I have my suspicions. To confirm or disprove those will take a little longer, but I am satisfied that he exists and I have broken his cipher. I deemed this sufficient cause to interrupt your supper.”
Six eyes turned toward Raffaino Sciara. I looked at him also, because I had never seen a skull look humiliated before.
“You will show Their Excellencies the restored plaintext?” Circospetto demanded acidly.
“I did not venture to pry into it all,” the Maestro said with false humility. I could tell he was enjoying himself hugely, although the others might not be reading the signals. “I have no need to know the Republic’s secrets. I deciphered one page, just to be sure, and most of it seemed to be street gossip with a few nuggets of intelligence. I can confirm that the key is the same in all the four documents. Alfeo?” He handed me the fair copy I had made for him, and I stepped forward to hand it up to Trevisan. Three heads almost banged together as the chiefs all tried to read it at once.
“So what is the cipher?” Sciara demanded, quite as furious now as he was supposed to be.
“A simple polyalphabetic,” the Maestro said mildly.
“I am impressed, Doctor.” Sciara had to admit that, however sourly, after his minions had failed to crack it. “I have always understood that there was no way of breaking a polyalphabetic cipher.”
The three chiefs were still muttering together, jabbing fingers at the plaintext.
“The simple Cardano form used by this Algol person is vulnerable,” the Maestro said, rubbing salt in the wound. “Had he followed the subtler recommendations of the sagacious Monsieur Vigenere and used the plaintext to encode itself, then even I might have failed to break it. As it is, I showed it all to Filiberto Vasco. He will explain the technique to you.” He stretched his lips in a helpful smile.
I came very close to exploding. The thought of Sciara taking lessons from dear Filiberto was exquisite.
“We are deeply impressed, Doctor,” Marino Venier growled. “This document appears to be genuine. As you saw, it does include some covert information.” The chiefs were all smiling, though. Their decision to consult Nostradamus had borne fruit and the skeptics within the Ten would have to eat their doubts. “You said you had other evidence for us?”
“Nothing that you can put before a court, messere. May I inquire who named this spy ‘Algol’?”
The heads exchanged glances. The outer two nodded. Trevisan said, “We have reason to believe that his employers refer to him by that name. A codeword or a joke, perhaps.”
“I fear it may be more,” the Maestro said. “I may speak in confidence, messere?”
“You have certainly earned that right.”
I certainly did not expect him to mention that his foresight had been blurred or my tarot confused, for that would be tantamount to a confession of practicing witchcraft, but he came close.
“I have detected occult interference with my work. I have even had a premonition that Algol will seek to entrap me, planning to destroy my usefulness to the Republic.”
“We shall provide additional guards!” Soranzo barked as the other two spluttered in alarm.
That was the last thing Nostradamus wanted. “No, messere! I do not expect the entrapment to take the form of physical violence, for that would be too easily traced back to him. The attack will be of a supernatural essence. I can take steps to defend myself and sier Alfeo from it, but others would be more vulnerable. Even the admirable vizio -and I assure you that I have absolute faith in Filiberto Vasco’s loyalty and dedication-even the vizio could be corrupted by black art. I ask that you remove him from my premises. His sword cannot defend against the powers of darkness, and he may merely get in the way of what I propose to do.”
Neatly done, I thought. He had used Vasco to rid himself of Danese and now was getting rid of Vasco also. That would be convenient, as long as he did not find Algol taking their place.
“May we inquire exactly what that is?” Soranzo asked narrowly. “Just what are you proposing to do?” Although far from being an outright skeptic like the doge, he was ranking doubter among the three chiefs.
“I propose to unmask Algol,” the Maestro said testily. “Quite apart from menacing the beloved Republic of which I have the honor of being an adopted citizen, he has used demonic powers against me and my apprentice, an intrusion I shall not tolerate. Doubtless he was originally a loyal subject of his ruler, who believed that he was serving a noble cause when he began to dabble in black arts, but the laws of demonology are infrangible, and he has undoubtedly fallen into the power of the Powers he sought to control. I shall identify him and report him to-”
I thought for a moment that he was going to continue, “-Holy Mother Church for exorcism.” That would have been disastrous. The last thing Venice ever wants is the Vatican trying to meddle in its affairs of state. He caught himself in time. “-your honored selves.”
The chiefs had sensed the hesitation and were frowning.
“Just how do you propose to identify this demon-wielder you describe?” Trevisan demanded, perhaps imagining holy water being splattered in all directions in the name of the Council of Ten. That would not do, either.
