Sam remained seated. “Will anything happen? Will Sarah Allersby’s properties be searched or her bank accounts audited?”

The commander looked sympathetic. He sat down again. “I’m sorry, but those things will not happen. The armed gang was certainly one of the groups who patrol the north to protect the ranches where drugs are grown and shipped. Marijuana is a stable, reliable crop that can be grown in any remote area by anyone. But there’s no proof of a connection with Sarah Allersby. Any piece of jungle—including national parkland—can be infiltrated by these criminals. We raid them and they turn up elsewhere. When we go away, they come back. Do they pay a landlord for the privilege? Sometimes, but not always. Your report of seeing coca trees, frankly, disturbs me most. We haven’t had coca growing here. Until now, we’ve only been a stop on the route from South America.”

“If you were to have a reason to search the Allersby houses, banks, and businesses for one thing and found another, could you still arrest her?”

“Yes, provided we had a good legal reason to search. This time, we don’t have a direct connection to her.” He seemed to make a decision. “I’m going to tell you something confidential. Like many rich and active businesspeople, she has been investigated from time to time. In fact, it’s happened twice that I know of in this office. We found nothing.”

Remi said, “No money she couldn’t explain? No Mayan artifacts? She calls herself a collector, and we saw plenty in her house.”

The commander said, “If she has money she didn’t declare here, it’s no mystery. She has interests in many countries, and a wealthy family. If there are Mayan artifacts, she could say they were part of the estate she bought from the Guerrero family or some things her workers found recently that she would have reported. There’s nothing criminal there unless she did something definite and final—sell them or take them out of the country.”

“What would you advise us to do?” asked Remi.

“What Miss Costa undoubtedly told you to do. Go home. If you want to, you could search the online markets for codices or parts of them. Often, things are broken up and sold. If the codex turns up, we’ll file charges and confiscate it.”

“Thank you,” said Remi.

Sam shook the commander’s hand. “We appreciate your willingness to listen.”

“Thank you for your evidence. And please don’t be discouraged. Justice is sometimes slow.”

Amy Costa had the embassy car drop them off at their hotel. Once they were in the room, they called Selma and asked her to get them a flight back to the United States. While they were waiting to hear from her, they went out to an English-language bookstore to buy books to read on the long flight home.
