(Sorry if I got the wrong book)
In chapters 12 and 13 of "Dance Hall of the Dead" by Tony Hillerman:
Chapter 12: Jim Chee, a Navajo Tribal Police officer, continues his investigation into the disappearance of two boys from Zuni reservation. He learns more about the cultural differences between the Navajo and Zuni tribes and starts to unravel the mystery surrounding the boys' disappearance.
Chapter 13: Chee makes significant progress in his investigation, uncovering crucial clues that lead him closer to the truth. He encounters obstacles and challenges along the way, but his determination drives him forward. The chapters build suspense as Chee gets closer to solving the case.
These chapters likely involve character development, plot progression, and the exploration of themes such as cultural differences and the importance of tradition in Native American communities.
