Summoned to the Honolulu hilltop mansion of radio pitchman Barry Buckingham, presumably to trace his missing wife, the Surfing Detective is in for the letdown of his career. Kai Cook is hired to track another lost family member. A dog.

Despite his qualms, Kai would seem a natural for the case, since the golden retriever named Kula is a famous surfing dog. Yet the PI knows nothing about finding missing pets. But he does know where to find help—Maile Barnes, an ex-K9 cop and kindred spirit with the keys to unlock the dark underworld of animal theft in the islands.

Then a questionable tip takes Kai to a late-night rendezvous, his tipster winds up dead, and the detective himself becomes a suspect. Can he clear his name and find the murderer before he strikes again? The PI tracks the illusive retriever from O'ahu to the Big Island to Maui, but the killer is one step ahead—other players linked to the dog's disappearance keep turning up dead.

Is a ghost from Barry Buckingham's past behind the murders? Or is Kai's client just a misunderstood man with a lost pet? To solve this third case in the Surfing Detective series, Kai Cooke must do what he never does—take on a partner. Teaming up with the headstrong K9 cop is his only shot to liberate the famous surfing dog, who is somehow always at the center of this mystery.
