Harry does some deep sea detective work while investigating the fishy disappearance of his worst enemy in this eighth Shark School (mis)adventure.

Harry Hammer’s all-time favorite TV show is Mike Hammerhead, Shark Detective.

The fin-tastic detective never fails to solve under-the-sea ‘who-dunnits’ and now Harry has found himself in similar water when he investigates the disappearance of his worst enemy Rick Reef. Has his nemesis gone missing or gone fishing?!
