This Quetzalcoatl statuette, this symbol of the Mexica Tenochca, was incomplete. Garza knew what was missing--or, more accurately, he knew the missing piece would not resemble anything in the Aztec pantheon. It was this thought that kept him awake at night. As the symbol of the Mexica Tenochca movement since the day Garza had founded it, this statuette had become a rallying cry for the wave of nationalism that had swept him into office. Should its credibility be called into doubt . . . It was a question Garza didn't dare entertain. The thought that a lost nineteenth-century warship could destroy everything that he'd built was unacceptable. All of it gone because of a trinket or artifact found by a random snorkeler, who in turn shows it to someone with a passing interest in history, who then asks an expert. A falling domino that destroys a nation's restored pride.

THE BUZZ OF THE INTERCOM on Garza's desk shook him from his reverie. He turned off the case's halogen light and returned to his desk.

"Yes?" he said.

"He is here, Mr. President."

"Send him in," Garza said, then turned and sat down behind his desk.

The double doors opened a moment later and in strode Itzli Rivera. At six feet tall and one hundred fifty pounds, Itzli Rivera appeared unsubstantial from a distance--gaunt in the extreme, his narrow face of angles and planes dominated by a hawk nose--but as he came closer Garza reminded himself how deceptive Rivera's appearance was. It showed in the hard set of his eyes and mouth, in his steady, purposeful gait, and in the taut muscles and the tendons of his bare forearms. Even without knowing the man, an astute observer could easily see Itzli Rivera was no stranger to hardship. Of course, Garza knew this to be true. His chief operative had indeed visited hardship upon many poor souls, so far most of them political opponents who didn't share Garza's vision for Mexico. Luckily, it was easier to find a virgin in a brothel than it was to find an incorrupt member of the Senate or the Chamber of Deputies, and Rivera had a knack for finding a man's weakness, then shoving the dagger home. Rivera was himself a true believer, having rejected his Spanish name, Hector, in favor of Itzli, which in Nahuatl meant "obsidian." A fitting name, Garza thought.

A former major in the Grupo Aeromovil de Fuerzas Especiales, or Special Forces Airmobile Group, GAFE, and former Secretariat of National Defence's S-2 Intelligence Second Section, Rivera had left the army to become Garza's personal bodyguard, but Garza had quickly seen Rivera's wider potential and had put him to work as his own private intelligence and operations director.

"Good morning, Mr. President," Rivera said stiffly.

"And to you. Sit down, sit down. Can I get you something?" Rivera shook his head, and Garza asked, "To what do I owe this visit?"
