The Curious Cape Cod Skull — Marie Lee

In this first novel of Marie Lee's Cape Cod mystery series, amateur sleuth Marguerite Smith finds a dead body in her well shed. The deceased turns out to be Peter DaFoe, a handsome Cambridge archaeologist who has been leading an excavation of an ancient Native American homesite. Pet is (or was) the black-sheep scion of a blue-blood Boston family; his gorgeous wife, Jennifer, holds a large insurance policy on his life.

When Marguerite's dog unearths a mysterious old skull near the scene of the crime, a fascinating puzzle unfolds. If Marguerite's theory is correct, the skull represents a find that will rock the entire archaeological world and make someone very, very famous.

The list of suspects expands to include Peter's loyal(?) assistants and his ambitious, envious boss. And to Marguerite's dismay, it seems that the murderer might even turn out to be a member of her own family!
