Wyoming's beloved lawman must solve his coldest case yet when a T. rex skeleton surfaces--along with a dead rancher--in Absaroka County.

When Jen, the largest, most complete Tyrannosaurus rex skeleton ever found surfaces in Sherriff Walt Longmire s jurisdiction, it appears to be a windfall for the High Plains Dinosaur Museum until Danny Lone Elk, the Cheyenne rancher on whose property the remains were discovered, turns up dead, floating face down in a turtle pond. With millions of dollars at stake, a number of groups step forward to claim her, including Danny s family, the tribe, and the federal government. As Wyoming s Acting Deputy Attorney and a cadre of FBI officers descend on the town, Walt is determined to find out who would benefit from Danny s death, enlisting old friends Lucian Connolly and Omar Rhoades, along with Dog and best friend Henry Standing Bear, to trawl the vast Lone Elk ranch looking for answers to a sixty-five million year old cold case that s heating up fast. --publisher marketing
