The Headhunter is loose on the streets of Vancouver.The victims are everywhere — floating in the Fraser River, buried in a shallow grave, nailed to an Indian totem pole on the university campus. All are women. All are headless.Then the photographs arrive. Carefully posed shots of the women's heads stuck on poles.The Mounties of Special X are up against a unique brand of killer. A killer whose sexual psychosis stretches back through Ecuador's steaming jungle and a scream-filled New Orleans dungeon to a dead-of-winter manhunt in the Rocky Mountains a century ago.
