Thanksgiving is approaching and Suzy and the gang are preparing for their annual dinner at the restaurant as well as dealing with the onset of winter. And when Suzy and the Chief spot what they believe is a bear cub on a local island, they're drawn into a bizarre and dangerous situation involving a crime ring operating in the area that is smuggling people across the border from Canada. And when the bear cub turns out to be an enormous Tibetan Mastiff, it soon becomes apparent they are dealing with a 'blast from the past.'Doing everything she can to remain on her best behavior and keep her mother from going off the planet, Suzy, at first, remains on the periphery of the investigation. But she is increasingly unable to stay on the sidelines as events heat up and become even more bizarre. And when things turn personal, she simply can't help herself and is determined to help the Chief and the FBI put a stop to the human trafficking ring as well as deliver some well-deserved justice to a dognapper.With a cast of characters that includes Rooster's cousin, Walter, a man with bad vision and a propensity to consistently do the wrong thing, and two FBI agents, one who finds Suzy's 'snooping' most annoying, the Case of the Tenacious Tibetan ramps us quickly as the gang tries to solve a complex puzzle while dealing with frigid boat rides and an early winter storm.
