Fog curled around Blackthorn Manor’s worn slate gables as the hall’s grandfather clock finally struck thirteen hoarse off-key chimes tonight. A shivering young librarian stepped off the back stairs tripping over something warm sticky seeping across the oak entryway’s planks. She lifted her flashlight beam to find their host’s limp frame draped over the broken cherrywood dining room’s heavy table. His famed 1920s emerald pocket watch that hung above the mantel had vanished without a single trace or faint clue. Muffled footsteps thundered down the west wing’s halls as other guests woke to her sharp terrified screams cutting through dampness. Every person trapped under that manor’s leaking roof hid a motive that could turn them from suspect to cold-blooded killer.
