"No, my friend, ten each-one lot for you, and one for Niccol here. You can count me out."

Two days later, the bombs were ready. Each was about the shape and size of a grapefruit, encased in steel and fitted with a catch at the top.

"How do they work?"

Leonardo smiled proudly. "You flip this little catch-actually, it's more of a lever-you count to three, and you throw it at your target. Each of these is enough to kill twenty men and, if you hit it in the right place, to disable a ship completely, even sink it." He mused. "It's a pity there isn't time to build a submarine."

"A what?"

"Never mind. Just throw it after a count of three. Don't hold on to it any longer, or you'll be blown to pieces yourself!" He rose. "And now, goodbye, and good luck."

"What?"

Leonardo smiled ruefully. "I've had quite enough of Spain and I've booked a passage with Alberto. He sails on this afternoon's tide. I'll see you back in Rome-if you make it."

Ezio and Machiavelli looked at each other. Then each solemnly embraced Leonardo.

"Thank you, my dear friend," said Ezio.

"Don't mention it."

"Thank God you didn't build these things for Cesare," said Machiavelli.

After Leonardo had gone, they carefully packed the bombs, of which there were exactly ten each, into linen bags, which they slung around their shoulders.

"You take the mercenaries' encampment; I'll take the port," said Ezio.

Machiavelli nodded grimly.

"When we've done the job, we'll meet at the corner of the street where the Lone Wolf is," said Ezio. "I reckon the Lone Wolf is where Cesare will have his center of operations. There'll be chaos and he'll go there to regroup with his inner circle. We'll try to corner them before they can make their escape-again."

"For once I'll back your hunch." Machiavelli grinned. "Cesare is so vainglorious he won't have thought to change the Borgia diehards' hideout. And it's more discreet than a palazzo."

"Good luck, friend."

"We'll both need it."

They shook hands and parted on their separate missions.

Ezio decided to go for the troopships first. Blending in with the crowd, he made his way down to the port and, once on the quay, selected his first target. He took out the first bomb, fighting down the insidious doubt that it might not work, and, aware that he'd have to work very fast, flipped its catch, counted to three, and flung it.

He was working at close range and his aim had a deadly accuracy. The bomb landed with a clatter in the belly of the ship. For a few moments, nothing happened, and Ezio cursed inwardly. What if the plan had failed?

But then there was an almighty explosion, the ship's mast cracked and fell, and splintered wood was tossed high in the air everywhere.

Amid the chaos that followed, Ezio darted along the quay, selecting likely ships and throwing his bombs. In several cases, the first explosion was followed by a mightier one-some of the troopships were evidently already laden with casks of gunpowder. In one case, an exploding ship carrying gunpowder destroyed its two neighbors.

One by one, Ezio wrecked twelve ships, but the chaos and panic were of great value. And in the distance he could hear explosions, and the shouts and screams that followed them, as Machiavelli did his work.

As he made his way to their rendezvous, he hoped his friend had survived.

All Valencia was in uproar, but pushing his way against the flow of the crowd, Ezio made the appointed spot in ten minutes. Machiavelli wasn't there, but Ezio didn't have long to wait. Looking a bit shabby, and with a blackened face, his fellow Assassin soon came running up.

"May God reward Leonardo da Vinci," he said.

"Success?"

"I have never seen such pandemonium," replied Machiavelli. "The survivors are running away out of town as fast as they can. I think most of them will prefer the plow to the sword after this."

"Good! But we still have work to do."

They made their way down the narrow street and arrived at the door of the Lone Wolf. It was closed. Silently as cats, they climbed to the roof. It was a one-story building, bigger than it appeared from the front, and near the top of the slant of the roof there was a skylight. It was open. They approached it and cautiously looked over the edge.

It was a different room from the one in which they had been ambushed. Two men were down below. Micheletto stood at a table. Facing him, seated, was Cesare Borgia. His once-handsome face, now lacerated by the New Disease, was white with fury.

"They have destroyed my plans! Those damned Assassins! Why did you not destroy them? Why did you fail me?"

"Eccellenza, I-" Micheletto looked like a whipped dog.

"I must make good my escape. I'll go to Viana. Once I'm there, I'll be in Navarre, just across the border. Let them try to recapture me then! I'm not waiting here for Ferdinand's men to come and haul me back to La Mota. My brother-in-law is king of Navarre and he will surely help me."

"I will help you, as I have always helped you. Only let me come with you." will help you, as I have always helped you. Only let me come with you."

Cesare's cruel lips curled. "You got me out of La Mota, sure. You built up my hopes. But now look where you have got me!"

"Master, all my men are dead-I have done what I could."

"And failed!"

Micheletto went white. "Is this my reward? For all my years of faithful service?"

"You dog, get out of my sight. I discard you! Go and find some gutter to die in."

With a cry of rage, Micheletto hurled himself at Cesare, his huge strangler's hands flexed to close on his former master's throat. But they never got there. With lightning speed, Cesare had whipped out one of the two pistols he had in his belt and fired, at point-blank range.

Micheletto's face was destroyed beyond all recognition. The rest of the body crashed over the table. Cesare sprang back, out of his chair, to avoid being covered in blood.

Ezio had drawn back, to be invisible but not out of earshot. He was preparing to leap from the roof and grab Cesare as he came out through the front door of the inn. But Machiavelli had craned forward the better to witness this dreadful showdown. Now, he inadvertently kicked a tile loose, and the noise alerted Cesare.

Cesare looked up swiftly, drawing his second pistol at the same time. Machiavelli didn't have time to draw back before Cesare fired, shooting Machiavelli through the shoulder and smashing his collarbone. Then Cesare fled.

Ezio thought of pursuit, but only for an instant, and he had heard that Cesare intended to go to Viana. Well, he would follow him there. But not before he had seen to his wounded friend.

Machiavelli was groaning, apologies of all things, as Ezio managed to haul him off the roof. At least he could walk, but the wound was bad.

Once they had got to the main thoroughfare, Ezio accosted a passerby, having to stop the man by force since the chaos was still raging around them.

"I need a doctor," he said urgently. "Where can I find one?"

"Many people need a doctor!" replied the man.

Ezio shook him. "My friend is badly wounded. Where can I find a doctor? Now!"

"Let go of me! You could try el medico el medico Acosta. His rooms are just down the street. There's a sign outside." Acosta. His rooms are just down the street. There's a sign outside."

Ezio grabbed the near-fainting Machiavelli and supported him. He took his scarf from his tunic and with it stanched the wound as best he could. Niccol was losing a lot of blood.

The minute he saw the wound, Acosta had Machiavelli sit in a chair. He took a bottle of alcohol and some swabs and carefully dressed it.

"The ball went right through the shoulder," he explained in broken Italian. "So at least I won't have to dig it out. And it's a clean wound. But as for the collarbone, I'll have to reset it. I hope you're not planning on traveling any time soon."

Ezio and Machiavelli exchanged a glance.

"I have been a fool again," said Machiavelli, forcing a grin.

"Shut up, Niccol."

"Go on. Get after him. I'll manage."

"He can stay here with me. I have a small annex that needs a patient," said Acosta. "And when he's healed, I'll send him after you."

"How long?"

"Perhaps two weeks, maybe more."

"I'll see you in Rome," said Machiavelli.

"All right," replied Ezio. "Take care of yourself, my friend."

"Kill him for me," said Machiavelli. "Though at least he spared us the trouble of Micheletto."

PART III.

We have reached the last era in prophetic song. Time has conceived, and the great sequence of the ages starts afresh. Justice, the virgin, comes back to dwell with us, and the rule of Saturn is restored. The Firstborn of the New Age is already on his way from high heaven down to earth.-VIRGIL, ECLOGUES ECLOGUES, IV

SIXTY-THREE.

Ezio once again traveled across Spain on a long, lonely journey, almost due north to Viana. He arrived there in the month of March. The city that he saw, a mile or so distant, looked exactly like the one in the vision accorded him by the Apple, with strong walls and a well-fortified citadel at its center, but there was a difference.

Even before he crossed the border into Navarre, Ezio's practiced eye told him that the city was under siege. When he came to a village, most of the locals just shook their heads dumbly when he questioned them, but when he sought out the priest, with whom he was able to converse in Latin, he learned the whole picture.

"You may know that our king and queen have designs on Navarre. It's a rich land, and they want to incorporate it into ours."

"So they want to take Viana?"

"They've already taken it! It's occupied by the Count of Lerin on their behalf."

"And the besiegers?"

"They are Navarrese forces. I think they will be the victors."

"What makes you say that?"

"Because they are under the command of the brother-in-law of the king of Navarre, and he is an experienced general."

Ezio's heart beat faster, but he still needed confirmation: "His name?"

"He's very famous, apparently. The Duke of Valence, Cesare Borgia. They say he once commanded the army of the Pope himself. But the Spanish troops are brave. They have taken the fight out to the enemy, and there have been bloody battles in the fields outside the town. I would not go any farther in that direction, my son; there lies only devastation and blood."

Ezio thanked him and spurred his horse forward.

He arrived at the scene to find a pitched battle going on right in front of him, as a fog grew around them. In its midst Cesare Borgia was taking a stand, hacking down any foe who came at him. And suddenly Ezio him -self had to fight another horseman-a Navarrese, with his crest of a red shield crisscrossed with yellow chains. They cut and slashed at each other with their swords until finally Ezio was able to split the man's right shoulder down to the chest, and he fell, without a cry, to be finished off by Spanish infantrymen.

Cesare was on foot, and Ezio decided that it would be easier to get close to him undetected if he were also on foot, so he dismounted and ran through the fray toward him.

At last he stood face-to-face with his deadly foe. Cesare's face was streaked with blood and dust, and strained with exertion, but when he saw Ezio his expression took on a new determination.

"Assassin! How did you find me?"

"My thirst to avenge Mario Auditore led me to you."

They sliced at each other with their swords until Ezio managed to knock Cesare's out of his hand. Then, sheathing his own, he flung himself on the Borgia, putting his hands around his throat. But Cesare had learned a few things from Micheletto about the art of strangling and managed to free himself by thrusting Ezio's arms away. Ezio unleashed the hidden-blade, but once again Cesare managed to defend himself successfully, as the battle raged about them.

But then the Spanish trumpets sounded the retreat. Triumphant, Cesare yelled to the nearest Navarrese troops: "Kill him! Kill the Assassin! Tear the maldito bastardo maldito bastardo into pieces!" into pieces!"

But the fog had increased, and Cesare melted into it. The Navarrese soldiers closed in on Ezio. He fought them off hard and long. They left him for dead.

Later, Ezio came to, to find himself in the middle of the battlefield. He was lying on his back. He had to push a corpse off him before he could sit up.

The battlefield lay under a cloudy, bloodred sky. In the distance the sun burned angrily. Dust hung in the air over a wide, unmade road, littered with the dead.

Ezio saw a crow standing on a corpse's chin, pecking hungrily at his eye. A riderless horse stampeded by, driven mad by the smell of blood. Broken banners snapped in the breeze.

Groaning with the effort, he stood up and, painfully at first, walked through the field of the dead. He found that he had lost his sword and dagger, though the hidden-blade and the bracer had not been found and looted.

His first job was to replace his weapons. Near him, he noticed a peasant sifting through the battlefield, looting. The peasant looked at him.
