How do you solve a crime if you’re just a child?
My name is Billy, and I live on a cliff on an island. I’m eleven, but I’m not like my peers, because I’m a real scientist—marine biologist. Recently, I had to become a detective too.
It all started with the disappearance of a girl named Olivia. The police found no clues, but I did. I was there that night and I saw something important. Besides, no one knows the local sands, rocks, bays, and caves better than I do.
You probably haven’t met anything like this. The investigation Billy carries out has a special style. Soon he finds himself at the center of a tangled web of lies and family secrets. His childhood game at being a detective turns into a fight for survival. He becomes the target of a killer who knows him. Now he has to uncover this case to save his own life.
