How do you catch a killer - when you're just a kid? A teenage girl disappears from a beach town at the height of summer. Two months later the police still can't find her. And a quirky 11-year-old steps in to help. Billy can't tell anyone what he's up to, but he's confident of success. After all, he's something of a child prodigy (or at least he thinks he is). Either way, he's got very good reasons to want the police and coastguard off his beach. With an investigative style you won't see in any police textbooks, he follows the twists and turns of the case. But as all the clues begin to point towards one suspect, Billy realises he's in trouble. Because the person who took the girl is someone he knows. And when they find out Billy is onto them, they're going to need him dead. The Things you find in Rockpools is a gripping and twist-filled psychological-thriller from Amazon-bestselling author Gregg Dunnett.
