Rain polished the windows while midnight swallowed Blackthorn Manor whole. Detective Mara Voss arrived before the grandfather clock struck twelve. Inside, nine guests waited silently around the murdered host's chair. Sir Edmund's blood formed an arrow pointing toward the library. Yet every door was locked, and every key remained accounted. Mara noticed ten wet footprints crossing the otherwise dusty carpet. They began beside the corpse but ended beneath her feet. Then the grandfather clock chimed thirteen, startling everyone except Edmund.
