Ruth Galloway—whom #1 New York Times bestselling author Louise Penny calls "a captivating amateur sleuth"—investigates a string of murders deep within the abandoned tunnels of Norwich in award-winning mystery. Winner of the CWA Dagger in the Library Award ¶ Far below Norwich is a maze of old mining tunnels. When Ruth Galloway is called to examine a set of human remains in one of them, she notices the bones are almost translucent, a sign they were boiled soon after death. Once more, she finds herself at the helm of a murder investigation. Meanwhile, DCI Nelson is looking for a homeless woman who he hears has gone "underground." Could she have disappeared into the labyrinth? And if so, is she connected to the body Ruth found? As Ruth and Nelson investigate the tunnels, they hear rumors of secret societies, cannibalism, and ritual killings. And when a dead body is found with a map of what seems to be the full maze, they realize their hunt for the killer has only just begun—and that more bodies may be underfoot. ¶ The Ruth Galloway series is:¶ "Remarkable, delightful." —Associated Press ¶ "Wonderfully rich." —Guardian ¶ "Smart, down-to-earth." —Mercury News
