The old mansion loomed silently in moonlight. Dark shadows stretched across the cobblestone path. A single gas lamp flickered weakly outside. Footsteps crunched softly on the gravel drive. The front door stood slightly ajar now. A chill wind howled through broken windowpanes. Frosty breath misted in the frigid night air. A distant owl hooted, echoing hollowly. The victim’s body lay sprawled on the floor. Blood pooled darkly beneath their lifeless form. A silver pocket watch ticked slowly on the table. Its hands frozen at exactly midnight precisely. Fingers twitched once, then lay still forever. The killer’s footprints vanished into the garden. No one had heard a single scream.
