Dr. Larry Flienhart literally returns to Earth after four months on the International Space Station, discovering through long chats with Charlie that he has a long way to get his physical and metaphysical feet back on terra firma after his voyage of discovery turns into one of self-discovery. Meanwhile, the brothers use math analysis to probe into the mind of a notorious hit man, awaiting execution in San Quentin, who offers to solve a murder he says he committed during a kidnapping -- and find out why his story has a big hole in it.

When Charlie encounters Larry, he asks about the set of knotted strings draped around his neck. Larry refers to it as an "Aztec quipu" and says it was used in Tenochtitlan (the capital of the Aztec empire). Quipus, however, were used by the Incas of the Andes Mountains of South America, not the Aztecs of Mexico. A few hundred survive, but have not been definitively deciphered. It is thought that quipus encoded both numeric and verbal information, but a majority of the data examined so far appears to be numeric. See more
