Mark Stover was a talented dog trainer, better known as the dog whisperer of the Pacific Northwest. He was charismatic and attracted the attention of wealthy blonde heiress Linda Opdyke. They built a business together, along with a marriage. But Linda said Mark also had a dark side, and when she tried to leave the marriage, he obsessively followed. She sought the protection of a security expert, Michiel Oakes, who soon became the new love of her life -- her knight in shining armor. But when blood was found in Mark’s home and he was reported missing, detectives went looking for Michiel. In this dark love triangle, just who was the hunter and who was the hunted?
