Ben Bones and The Search for Paneta's Crown

Ben Bones, Genealogical Consultant and self-described Articulator of Family Skeletons, has been hired by the estate of arms manufacturer Benito Moschetto to find a missing family artifact. Benito's will bequeaths The Crown to his eldest male heir via primogeniture to hold in trust for the family, but the three siblings all want The Crown for themselves. The problem is that they don't know exactly what it is, or where it might be.
Bones finds himself in the middle of the family's intrigues. He is threatened, bribed, swims with hungry sharks (literally), and witnesses a deadly accident (or was it a murder?). Ben finds The Crown in the end, but only after bodies have piled up. A final ironic revelation will surprise you all. This book contains genealogical charts of the family members, Benito Moschetto's Last Will, and other pertinent documents.
