Sánchez tells the investigators that he has offered to help Larkin on a number of occasions, only to be ignored or rebuffed each time. His suspicion is that Larkin wishes to loot the site without interference. There are no legal restrictions in Peru to prevent foreigners from doing this—a fact that frustrates Sánchez deeply. Sánchez refers to people who would remove his country’s treasures in such a manner as huaqueros, a Quechua word that translates as “grave robbers.” Sánchez believes his only recourse is to identify the exact location of the pyramid and get there first, although time is running out. To this end, Sánchez and one of his students, Trinidad Rizo, have been going through the university library and archives for any possible information about the pyramid. They have found an old document dating from the mid-16th century, written by a conquistador by the name of Gaspar Figueroa, which may refer to the site in question. The document is difficult to read, so Rizo has been working on a summary that picks out the pertinent details. She has almost finished it but has had to stop for the moment to look for a related artifact in a storeroom under the museum. In fact, Rizo should be along soon to join the meeting; she’s just gone to fetch the artifact and will be back at any moment. While everyone waits for Rizo to arrive, Sánchez is happy to answer any questions the investigators may have about Peruvian history and archaeology. He is a rationalist and does not believe in kharisiri, ancient gods, or other aspects of what he considers to be folklore. If the investigators attempt to convince Sánchez that the kharisiri are real and that he may be in danger from them, his reaction is polite amusement. After some time, Sánchez apologizes for how long it is taking Rizo. If the investigators suggest looking for her, Sánchez says that he is happy for them to go and find her, but he suspects that she has simply found something interesting and lost track of the time. He gives them directions to the storeroom, located in a basement under the museum, and tells them that he will wait here with Elias in case she turns up in the interim (see The Storeroom and Rizo is Murdered, following).
