Who can a FBI agent and a scientist trust as they investigate a murder in the ghost town of Golden Gully? The medical examiner thinks the victim was tortured before he was killed. However, the ten residents in this remote town in the Gila National Forest deny knowing him, and the local sheriff's office is less than cooperative. This is the thirteenth book in the Science Traveler series with Sara Almquist as a science consultant to the FBI and other agencies.
