Bigfoot

Northwest detective John Denson and his partner, Indian shaman Willie Prettybird, on the trail of the legendary Sasquatch. Denson and Prettybird are hired to guide Russian primatologist Sonja Popoleyev up the slopes of Mt. St. Helens on her quest to determine what, if anything, Bigfoot might be, and, incidentally, to pick up the $100,000 prize offered for its capture by a local promoter. Their competitors include explorers and Bigfoot believers from all over the world. Before the expeditions can begin, the promoter and his brother are murdered, but the hunt for the creature goes on, with Denson wondering who among the searchers might have reason to kill.
