Death on the Greasy Grass — C.M. Wendelboe

FBI agent Manny Tanno is taking some much needed R and R at the site of the Battle of Little Big Horn. But when a death on the reservation cuts his vacation short, he learns that the secrets of the past have a way of stirring up trouble in the present.

As a scout for the legendary General Custer, Crow tribe member Levi Star Dancer kept a journal chronicling his exploits from the Battle of the Greasy Grass onward. Now, the missing journal has been found and the descendents of those mentioned in the account, including Levi's own, want to keep their family secrets hidden at all costs...

Manny's trip to the Crow Agency Reservation turns out to be ill timed when a reenactor of the Battle of Little Big Horn is killed right in front of him. It turns out the victim was the one who found Levi Star Dancer's famed diary and was planning on selling it to the highest bidder. And while the dead body is hard to miss, the coveted book is nowhere to be found. Now, Manny has to watch his back while searching for a murderer and the missing journal, because this slippery killer will do anything to make sure the past stays buried.
