The Judas Strain (Sigma Force 4)

As Marco slipped the robe over his head, his father noted what the son had drawn earlier in the sand with a stick. With a tightening of his lips, his father quickly ground it away under a heel and stared up at his son. A beseeching look fixed upon his visage. "Never, Marco .. . never . .."

But the memory could not be so easily ground away. He had served the Great Khan, as scholar, emissary, even cartographer, mapping his many conquered kingdoms.

His father spoke again. "None must ever know what we found ... it is cursed."

Marco nodded and did not comment on what he had drawn. He only whispered. "Citta dei Morti."

His father's countenance, already pale, blanched further. But Marco knew it wasn't just plague that frightened his father.

"Swear to me, Marco," he insisted.

Marco glanced up into the lined face of his father. He had aged as much during these past four months as he had during the decades spent with the Khan in Shangdu.

"Swear to me on your mother's blessed spirit that you'll never speak again of what we found, what we did."

Marco hesitated.

A hand gripped his shoulder, squeezing to the bone. "Swear to me, my son. For your own sake."

He recognized the terror reflected in his fire-lit eyes . . . and the pleading. Marco could not refuse.

"I will keep silent," he finally promised. "To my deathbed and beyond. I so swear, Father."

Marco's uncle finally joined them, overhearing the younger man's oath. "We should never have trespassed there, Niccol6," he scolded his brother, but his accusing words were truly intended for Marco.

Silence settled between the three, heavy with shared secrets.

His uncle was right.

Marco pictured the river delta from four months back. The black stream had emptied into the sea, fringed by heavy leaf and vine. They had only sought to renew their stores of fresh water while repairs were made to two ships. They should never have ventured farther, but Marco had heard stories of a great city beyond the low mountains. And as ten days were set for repairs, he had ventured with twoscore of the Khan's men to climb the low mountains and see what lay beyond. From a crest, Marco had spotted a stone tower deep within the forest, thrusting high, brilliant in the dawn's light. It drew him like a beacon, ever curious.

Still, the silence as they hiked through the forest toward the tower should have warned him. There had been no drums, like now. No birdcalls, no scream of monkeys. The city of the dead had simply waited for them.

It was a dreadful mistake to trespass.

And it cost them more than just blood.

The three stared out as the galleys smoldered down to the waterlines. One of the masts toppled like a felled tree. Two decades ago, father, son, and uncle had left Italian soil, under the seal of Pope Gregory X, to venture forth into the Mongol lands, all the way to the Khan's palaces and gardens in Shangdu, where they had roosted far too long, like caged partridges. As favorites of the court, the three Polos had found themselves trapped—not by chains, but by the Khan's immense and smothering friendship, unable to leave without insulting their benefactor. So at long last, they thought themselves lucky to be returning home to Venice, released from service to the great Kublai Khan to act as escorts for the lady Kokejin to her Persian betrothed.

Would that their fleet had never left Shangdu . . .

"The sun will rise soon," his father said. "Let us be gone. It is time we went home."

"And if we reach those blessed shores, what do we tell Teobaldo?" Masseo asked, using the original name of the man, once a friend and advocate of the Polo family, now styled as Pope Gregory X.

"We don't know he still lives," his father answered. "We've been gone so long."

"But if he does, Niccolo?" his uncle pressed.

"We will tell him all we know about the Mongols and their customs and their strengths. As we were directed under his edict so long ago. But of the plague here . . . there remains nothing to speak of. It is over."

Masseo sighed, but there was little relief in his exhalation. Marco read the words behind his deep glower.

Plague had not claimed all of those who were lost.

His father repeated more firmly, as if saying would make it so. "It is over."

Marco glanced up at the two older men, his father and his uncle, framed in fiery ash and smoke against the night sky. It would never be over, not as long as they remembered.

Marco glanced to his toes. Though the mark was scuffled off the sand, it burned brightly still behind his eyes. He had stolen a map painted on beaten bark. Painted in blood. Temples and spires spread in the jungle.

All empty.

Except for the dead.

The ground had been littered with birds, fallen to the stone plazas as if struck out of the skies in flight. Nothing was spared. Men and women and children. Oxen and beasts of the field. Even great snakes had hung limp from tree limbs, their flesh boiling from beneath their scales.

The only living inhabitants were the ants.

Of every size and color.

Teeming across stones and bodies, slowly picking apart the dead.

But he was wrong . . . something still waited for the sun to fall.

Marco shunned those memories.

Upon discovering what Marco had stolen from one of the temples, his father had burned the map and spread the ashes into the sea. He did this even before the first man aboard their own ships had become sick.

"Let it be forgotten," his father had warned then. "It has nothing to do with us. Let it be swallowed away by history."

Marco would honor his word, his oath. This was one tale he would never speak. Still, he touched one of the marks in the sand. He who had chronicled so much . . . was it right to destroy such knowledge?

If there was another way to preserve it. . .

As if reading Marco's thoughts, his uncle Masseo spoke aloud all their fears. "And if the horror should rise again, Niccolo, should someday reach our shores?"

"Then it will mean the end of man's tyranny of this world," his father answered bitterly. He tapped the crucifix resting on Masseo's bare chest. "The friar knew better than all. His sacrifice . . ."

The cross had once belonged to Friar Agreer. Back in the cursed city, the Dominican had given his life to save theirs. A dark pact had been struck. They had left him back there, abandoned him, at his own bidding.

The nephew of Pope Gregory X.

Marco whispered as the last of the flames died into the dark waters. "What God will save us next time?"
