The mansion stood eerily silent. Rain hammered against tall windows. Lightning illuminated the grand foyer. Butler Jenkins discovered the body. Lord Ashford lay completely still. Blood pooled beneath his head. The study door remained open. Papers scattered across the floor. A letter opener gleamed nearby. Someone screamed from upstairs suddenly. Footsteps echoed through empty halls. The grandfather clock struck midnight. No one could leave tonight. The bridge had washed out. Eight guests remained trapped inside. Each held a deadly secret. Inspector Shaw would arrive tomorrow. Until then, nobody felt safe. The killer walked among them. Another scream pierced the darkness.
