A missing teenager. A haunted manor. A killer who isn’t done yet. Rileigh Bishop and Mitch have faced their share of dangers, but nothing could prepare them for the horrors lurking in Shagbark Manor. Sixteen-year-old Hillary Scofield warned of blood-soaked visions, floating violins, and a body surrounded in a puddle of blood. Then she disappeared without a trace. Determined to find the girl, Rileigh digs into the manor’s grim history, uncovering the chilling tale of Crawford Tillman – a man who returned home nearly a century ago to find his family murdered by an axe-wielding killer. Now, a new killer appears to be imitating the murders, starting with Hillary. With each passing hour, the danger grows closer. If Rileigh can’t unravel the truth behind Shagbark Manor, Hillary won’t be the only one who disappears. Because this time, the killer has their sights set on Rileigh. One By One is the 10th novel in the Bishop Smoky Mountain Thrillers series by Lauren Street.
