When a range-riding cowboy discovers the body of a dead man in a remote canyon near timberline, it sets off an unanticipated chain of events. At the time there was certainly a dangerous grizzly bear in the area, but was this simply a tragic accident -- or was foul play involved? Set in southern Colorado and northern New Mexico around 1960, this adventure leads the Circle Cross ranch hands and local sheriff's deputies on a perplexing chase to unlock the mystery of a cold case that was warmer than they could have imagined.
