Two years after a murder has been solved and the killer put in jail, Bat Garrett is hired by an attractive widow to find out why her husband was killed. The police-and everyone else-say it was just a robbery gone bad, but she thinks differently.

With Jody Anderson-still on crutches from her horrific ordeal in “The Nice Guy”-by his side, Bat undertakes a case that leads him through an amateur archeological society in Dallas and into a centuries old mystery in the ancient ruins of Mesa Verde in southwest Colorado.

Did the unassuming banker uncover something someone else would rather have stayed hidden?
