In the sleepy coastal Maine town of Penhallow, a stranger dies on a train, drawing Historical Society Director, Rachel Tinker, and curmudgeonly retired professor, Griffin Tate, into a spider’s web of archaeological obsession and greed. With the help of the victim’s rival, they set out to locate the Queen of Sheba’s tomb. Their plans are stymied when a tug of war erupts between the sheriff and a state police detective who want to arrest the same man for different crimes. It’s up to Rachel to solve a mystery that includes two more murders, if she wants to unlock the soft heart that beats under Griffin’s hard crust.
