In this highly atmospheric mystery, Ruth Galloway--described by Louise Penny as "a captivating amateur sleuth"--and DI Nelson have their summer vacations horribly disrupted by a murder in a medieval Italian town where dark secrets are buried as deep as bones. It's not often that you're called to the Italian countryside on business, so when archaeologist Angelo Morelli asks for Ruth Galloway's help identifying bones found in picturesque Fontana Liri, she jumps at the chance to go, bringing her daughter along for a working vacation. Upon arriving, she hears murmurs of Fontana Liri's strong resistance movement during World War II, and senses the townspeople have a deeply buried secret. But how could that connect to the ancient remains she's been studying? Just as she's getting her footing in the dig, DCI Nelson appears, unexpectedly and for no clear reason. When Ruth's findings lead them to a modern-day murder, their holidays are both turned upside down, as they race to find out what darkness is lurking in this seemingly peaceful town.
