Book excerpt: When Donald MacIntyre, an avid off-trail hiker, fails to return from a quest to bushwhack through difficult terrain up to the top of the Jumpoff, a dramatic cliff in the Great Smoky Mountains National Park, the good-natured back country ranger Hector Jones leads a search and rescue team into the remotest depths of the Greenbrier section of the park and discovers the body. From the nature of MacIntyre's injuries, it's clear that he had fallen-or been pushed-from the top. The job of investigating the suspicious death goes to Sally Connolly, a 31-year-old detective with the Sevier County, Tennessee, sheriff's office. Due to Hector's expert knowledge of the terrain, Sally enlists his help in the investigation. Murder at the Jumpoff is a novel with a powerful sense of place and the story of unusual characters who challenge themselves to seek excitement, beauty and fulfillment from undiscovered, treacherous mountain landscapes and from those they dare to love.
