The snow had swallowed every sound when Detective Maren Ashford arrived at Blackwood Manor, her breath clouding in the brittle midnight air. She noticed the front door standing open, swinging gently, though the wind had died hours before the first telephone call. Inside, the grandfather clock ticked unevenly, each beat arriving late, as though the house itself struggled to remember its purpose. Lord Cedric Blackwood lay motionless across the Persian rug, one hand outstretched toward a locked cabinet, the other empty and cold. Nine guests remained in the manor, each with an alibi woven tightly enough to strangle suspicion yet loose enough to unravel. The housekeeper discovered him at half past eleven, she claimed, though her shoes told a different story written in wet snow.
