Don Julio was no one's fool. And I had not been wrong in my assessment of Mateo. Like Guzman, Mateo was unable to resist the temptation to acquire a treasure. All picaros shared the same fatal flaw: the soul of a knave.

Mateo looked hurt. "Don Julio, on my honor—"

"A dubious oath. Listen to me, amigos, like a priest I will grant you forgiveness for your sins; but unlike one, I can also keep you from the gallows—if you obey me and do the work I set out for you. These Knights of the Jaguar, as they style themselves, are well known to the viceroy. They are a small but violent group of indios who are determined to kill all Spanish and take control of the country."

"Give me a hundred men, and I'll bring you the heads of all of them," Mateo said.

"You couldn't do it with a thousand. You would never find them. The knights do not conduct themselves in the open. In the daytime they are simple indio farmers or hacienda workers. At night they are a murder cult that band together to kill Spaniards and indios who do not oppose Spanish rule."

"They have killed Spaniards?" Mateo asked.

"At least ten, perhaps more."

"I have never heard of such a thing!" Mateo said.

"The viceroy is withholding the information to keep people from panicking and spreading the fame of the cult. We are still dealing with scattered groups, but they must be stamped out. With the right leadership, an indio revolt could spread like wildfire. This naualli, despite his age, may be such a leader. We could have a widespread revolt on our hands, another Mixton War."

"Then let's roast the black magician's feet over a hot fire until he tells us the names of his knights," Mateo said.

"Amigo, you are so Spanish in your thinking," the don said. "That is exactly what the conquistadors did to Cuitláhuac, Montezuma's successor, after Tenochtitlan fell. They tortured him to find out where gold had been hidden. It didn't work after the conquest, and it would have even less effect today. These are no ordinary indio warriors, but fanatics. You," Don Julio indicated Mateo, "I am sure are familiar with the story of the Old Man and the Mountain. But," he smiled at me, "despite your wide range of knowledge, you may not be acquainted with this tale."

"I have not heard of an old man and a mountain," I said.

"Hundreds of years ago Christian armies went to the Holy Land to free it from the Infidels. During one of these crusades, a leader of a Muslim sect, Rashid ad-Din, sent his followers to murder his Arab enemies and Christian leaders. Because he had a mountain fortress, we called him the Old Man of the Mountain.

"Our people called his followers Assassins, a corruption of an Arabic reference to them being hashish smokers. Marco Polo, a traveler from Venice, learned that the Assassins used hallucinatory substances before committing their heinous crimes. While their minds were slaves to these drugs, the Assassins believed that they had traveled to Allah's Garden of Paradise. They then set out to murder their enemies, knowing they would be caught and killed themselves. But they believed that after they were killed, having completing their murder assignment, they would return to paradise.

"The Aztecs were even more adept at the use of drugs that control another's mind. One of the Jaguar Knights whom we managed to capture had taken drugs before his crime. Even under the most severe and enduring torture, he revealed little to the viceroy's men. The fact was that his mind was so altered by the drugs that he no longer knew the difference between his real existence and a place he called the House of the Sun."

"The House of the Sun is heaven beyond the eastern waters," I said. "When an Aztec warrior dies in battle, rather than going to the underworld, his spirit goes to this paradise."

Mateo tapped his sword on his boot. "This naualli may be the Old Man of the Mountain to these indios."

"Exactly," Don Julio said.

"And you want me to take this thieving little devil," Mateo waved the sword at me, "and find this practitioner of the black arts and get the truth from him."

"Almost. I want you to catch him in the act so we can hang him."

"I understand perfectly. But, of course, as a Spanish gentleman, I do not understand the language or the customs of these people. This fine young man should be sent to find this naualli. After he does, he can send for me. I will await his message at your house in the City of Mexico..."

Mateo stopped as Don Julio shook his head. "I think it would be better if you were nearby when the boy flushed out the Jaguars. That way you could protect him. Besides, as you pointed out, he is an untrustworthy cur who must be watched."

Mateo smiled at me; his eyes were not smiling. ¡Ay de mí! Once again he blames me!

The man was a wolf in picaro's clothes. Someday I would tell him a secret, but this was not the time. But, amigos, I will let you in on the secret. Do you remember what he called me? Bastardo. But that is a name he had heard years ago at the treasure fleet fair. Sí, he knows I am the very one for whom he chopped off a man's head.

FIFTY-NINE

The Healer claimed that all things were preordained in this world, that the gods had carved in stone books how our lives would unfold from the moment we were born. I believed that the gods had brought Don Julio into my life and sent me on this mission for a reason. Had I known the terrible consequences that were to occur because of my dealings with the dark magician, I would have tried to avoid the tragic fate by running into the forest and hiding from this strange Spanish don who was a doctor, scholar, and agent of the king.

That afternoon around the supper fire we received further instructions from Don Julio. Mateo plucked out little tunes on a guitar and drank wine from a goatskin as the don spoke.

"You are to direct yourselves to the indio town where you witnessed the sacrifice. There, find out where the naualli is. From what your uncle told you, he will be somewhere in the region. You will also come across other indio magicians, healers, and sorcerers. You can pick up gossip and information from them. We want to know about the Jaguar Knights, every bit of information you can learn.

"You are never to mention the Jaguar name. To do so in front of the wrong people would get your throat cut. Rather than questioning, which would do no good and raise suspicion, just listen. You are still a boy," he said to me, "and the indios will talk freely in front of you while they would not in front of a grown man. Keep your ears open, your mouth closed, and your feet ready to carry you quickly away.

"Mateo, you will need a cover identity, too." Don Julio thought for a moment. "Guitars. You will be a merchant of guitars. I will get you several mules. One of my indio vaqueros will be your assistant I will send for him immediately. When you need me, he will ride to wherever I am."

Mateo hit an irritating series of chords on the guitar. "I am a swordsman and a poet, not a merchant."

"You are doing the king's work in exchange for not being sent to the Filipinas. If I want you to put on a dress and be a puta, you will do that, too."

Mateo drummed the guitar and sang an old Spanish ballad.

Yesterday I was King of Spain,

Today not one village;

Yesterday I had towns and castles,

Today I have not one;

Yesterday I had servants,

And people to wait upon me;

Today there is not a battlement
