It's a find that could be worth millions of dollars.What makes The Treasure King unusual is not only its size, but the captain's boasts about knowing the location of the San Manuel-until someone murders him with a speargun. The cops don't have any easy answers, so they ask Rick to consult in the investigation. Now, Rick is having a strong sense of déjà vu, especially when his eleven-year-old daughter Alex has takes an interest in the case. The last thing he needs is Alex deciding the cops work too slowly and launching her own investigation-again.Rick knows Alex is precocious, fearless, and fueled by a strong sense of girl-power, but he doesn't expect her to ignore his warnings and sneak aboard The Treasure King. Once Alex is aboard, she finds more trouble than she bargained for. The cops accuse her of breaking-and-entering, and Rick must fight to keep her from becoming the town's youngest felon.Caught in the middle of the showdown between her dad and his friend Police Chief Adam Cunningham, Alex spills the beans about her trip aboard The Treasure King. Her information provides a clue that could break the case, but may be too late because the killer has decided to escape and disappear forever along with the location of the San Manuel.
