As winter deepens over the Blue Ridge Mountains, even the threat of snowstorms cannot derail this year’s Christmas run, not as long as “Sister” Jane Arnold has a say in it. With spirits high and traditions strong, a glorious parade of hunters in full holiday regalia gathers on the grounds of Tattenhall Station. But a blinding blizzard brings an early end to the sport. More disturbing: A horse soon returns without its rider. Gregory Luckham, a controversial presence as the president of a powerful energy company pushing for a pipeline through central Virginia, is the missing hunter. A search is organized for what is presumed will be a dead, frozen body. What is discovered, however, chills everyone to the bone—and points toward murder. Sister Jane will have to untangle a mystery packed as hard as snow—full of history, secrets, old wounds, and avarice.
