A fifth adventure for Gabriel Du PrÇ--Montana's MÇtis Indian fiddler and cattle-brand inspector (Notches, 1997, etc.). Here, Du PrÇ's rich friend Bart has been hired by a Japanese company to dig trout ponds (for a theme park, maybe?) at Le Doux Springs in the rugged foothills of the Wolf Mountains. The work has barely started when a minor earthquake turns up some ancient bones in the rock, possibly of the little-known Horn Star people. There are also rumors of a Tyrannosaurus rex skeleton in the area--which would be a find worth millions. Then comes the discovery of the body of archaeologist Robert Palmer--shot to death, a stolen snowmobile and a prehistoric tooth nearby. Du PrÇ, looking for answers, makes a trip deep into the mountains near the sheriff's ranch and is held for a while by members of a Crow tribe guarding a sacred site of their ancestors. He also has numerous conversations with resident archaeologist Dr. Burdette, aged Indian guru Benetsee, old Professor Morgenstern in Bozeman, and best friend Madelaine, all accompanied by heavy drinking and eating, and liberally laced with obscenities, before those answers emerge. Determinedly oblique goings-on--of interest, perhaps, to students of ancient cultures and the American West--but meager fare for puzzle lovers.
