Johnson's established formula (The Cold Dish; A Serpent's Tooth) works again in his 11th Walt Longmire mystery. When the largest T. rex skeleton, nicknamed "Jen," is discovered in Wyoming's Absaroka County, a chain of strange events follows. The body of rancher Danny Lone Elk is found floating in a pond, and Sheriff Longmire becomes entangled in another complex case. As the FBI, the media, the Cheyenne Conservancy, and a deputy U.S. attorney general establish themselves as heavy players in the contest for the priceless "Jen," the mystery surrounding Danny's death becomes crucially intertwined with the dispute over ownership of the bones. As usual, Walt and Henry Standing Bear battle an army of thugs, politicians, protective family members, and bureaucracy in their quest to "save Jen." Verdict Beloved series sidekicks, Johnson's trademark humor, Walt's recurring visions, and a winding plot make for satisfying reading. The author efficiently sets up a jumping-off point for the next Longmire installment while neatly resolving Lone Elk's strange death. Not to be missed.-Jeffrey W.
