Commodore Island Mysteries: The Case of Mona Lisa's Mustache

By Thomas Olis

Jenny's acquaintance, Brinsly, is forced to do something she doesn't want to do-vandalize a picture of the Mona Lisa that hangs in the library at their school by smearing paint across her face.

It's not just any paint, it's military-grade, designed to coat submarines. Why would that be important? And it's not just any painting, it's La Gioconda Torlonia. On loan from a wealthy donor, it is believed to be a potentially valuable, early version of the Mona Lisa, painted by Leonardo DaVinci himself

Jenny has reason to believe Brinsly may be involved and tries to reach out to her. Brinsly declines the help-she is dealing with more urgent trouble at home. But when the bully targets Jenny, she, Molly and Lora are forced into action. Why does the bully think he can push girls around? Was it just a random act of vandalism that the bully forced Brinsly to commit? Will they have the courage and the maturity to face down the grown-up leading the villainy?

In the second installment of the Commodore Island Mysteries, our protagonists find themselves caught up in a fast-paced adventure with the fate of a valuable painting-and their friend's future-caught in the balance. They prove, once again, that growing up-like solving mysteries-is far from easy, but the right set of friends make it an incredible adventure.
