But all is not as it appears. James soon discovers that the seemingly peaceful island harbors some strange secrets. Before long, Victor's house has been ransacked and important pieces of artwork have been stolen.

But one of his teachers has been acting strangely as well .

As a young girl's life hangs in the balance, it's up to James to uncover an intricate conspiracy that will take him head to head with enemies more ruthless than he could have ever imagined.
