Martha's Vineyard has been home to Victoria Trumbull for most of her 92-years, and in a near century she has learned much about life. Victoria Trumbull's keen hearing results in the discovery of a mutilated body in the harbor at Martha's Vineyard. But granddaughter Elizabeth, who works in the harbor office, and her boss, an ex-New York cop named Domingo, realize that the murderer may now target Victoria as a witness. Because the victim had ties to several town officials, the murder has ramifications that may affect the harbor office as well. The following days are filled with car chases, a spacey Wampanoag Indian, a missing harpoon, another murder, and additional suspects.
