Russell was already preparing for the trip while he listened. He took a suitcase out of his closet and set it on the bed. “I’ll let you know as soon as there’s anything to report.”

“Thank you, Russell.”

Next, Russell called the number of Jerry Ruiz, the man who had impersonated the Mexican Minister of Culture when they had confiscated the codex. “Hi, Jerry. This is Russ. I’d like you with me on a surveillance job.”

“Where?”

“It’s back in San Diego, but it could go anywhere from there. We’re to keep track of a couple, period. We can split what Sarah gives us, even.”

“It’s for her? Okay, I’m in.”

“I’ll pick you up in a half hour.”

Russell hung up and returned to his suitcase. He packed the sets of clothes he used for surveillance—black jeans and navy blue nylon windbreaker and black sneakers, baseball caps in several colors, some olive drab hiking pants that unzipped into shorts, a couple of sport coats in navy and gray, some khaki pants. He and Ruiz would fly down and rent a car and after a couple of days he would turn it in and get another one. He had found over the years that even a minor change in his appearance had a dramatic effect. Just putting on a hat and a different jacket made him a new person. Alternating drivers, getting out of the car and sitting at a restaurant table, made him invisible.

He completed his packing by throwing in some equipment: a shooter’s 60-power spotting scope, with a small tripod, and his personal weapons and some ammunition. He knew that Ruiz would come prepared. Ruiz habitually carried a pistol, even in Los Angeles, and had a boot knife, because that was the way he had come up. He had been a collector for a street gang as a teenager and then he became a cop for a while. It was a strange twist that as he’d come into middle age, he had begun to look like a Mexican politician or a judge. His appearance made him a good man for the job. He wasn’t automatically a suspect. He was also fluent in Spanish and that helped many times.

When Russell took this kind of job, he liked to have more time to prepare, but he would manage. He threw in his passport, five thousand dollars in cash, and a laptop computer. He closed his suitcase and went out to his car. He locked the house, then stopped for a second to be sure he’d forgotten nothing essential. Then he got into the car and drove toward Ruiz’s house, thinking about the job.
