“Caves?” The blue eyes danced with excitement. “Quite an extensive network. I've seen them. From the drawings on the walls, I'd say they've been occupied off and on going back to ancient times. The Basques, or others, may have been using them for hundreds, maybe thousands, of years.”

“Blackthorne mentions the caves in his narrative. In fact, they were instrumental in his story.” “In what way?”

“Aguirrez could easily have outdistanced his pursuers and fled to North America, where Brasero would never find him. The Basques were the only mariners intrepid enough to sail the Atlantic in those days. But Diego knew that Brasero would go after his family. And he knew that even if he stashed the relics in North America, when he returned to Europe, Brasero would be waiting.”

“Maybe he decided to take a stand for the most primal of reasons,” Austin said. “He wanted his revenge on the man who had ruined his life and stolen his fortune.”

“No disagreement there. Brasero was just as determined to finish the job he'd started. He had switched from his galley to a warship twice the size of Diego's caravel. He had put Blackthorne in com- mand. The ship bristled with guns that would have made short work of the Basques. But Diego knew from their previous encounter of the informant on board Brasero's ship and prudently moved the caravel away from the caves. Diego stationed a handful of his men on shore, where they could be seen by Brasero, and when Martinez launched his boats, the men ran into the caves, drawing their pursuers after them.”

“I smell a trap.” "You've got a better nose than Martinez, although in fairness, he

was probably distracted by thoughts of all the fun he was going to have burning Diego and his crew."

“Shades of Custer's Last Stand. That cave system is a labyrinth. Perfect to stage an ambush.”

“Then I'm sure you won't be surprised to hear that's what hap- pened. It was a two-pronged strategy. The caravel swept down on the warship and cowed its skeleton crew with a few cannon shots. Then they boarded the ship and took it over. Meanwhile, Diego launched his ambush. He had dragged one of his ship's cannon into the caves and used it to take the wind out of the attack.” Perlmutter raised a pudgy fist as if he were reliving the battle. “Brasero was a skilled swordsman, but Aguirrez was better. Instead of killing him, he toyed with Martinez before he doused Brasero's flame forever.”

“Where was Mr. Blackthorne in all this?”
