400 years after the "first Thanksgiving," a luncheon for leaders of GreenHome LLC and the Wampanoag tribe ends in murder. Or does it? Was Harriet Benbow killed to stop her from building luxury condos on an ancient burial ground? As payback for snatching an Art Deco toastrack at a yard sale? Or mistakenly by a burglar? In the seaside village of Quansett, untangling a violent crime takes collaboration. Detective Pete Altman wonders: Why did the killer cut upthe victim's scalp? Soup-chef Lydia Vivaldi and Wampanoag pastry chef Mudge Miles wonder: Is someone trying to frame the Indians? Reclusive artist Edgar Rowdey, who'd rather be plotting his new Agatha Christie pastiche, wonders: What about the toastrack?
