The rain hammered the windows of Blackwood Manor that night. Detective Sarah Chen arrived just after midnight, feeling deeply uneasy. A scream had shattered the silence hours before her arrival. Now the old house stood silent, its secrets carefully hidden. Inside, Lord Edmund Blackwood lay dead in his locked study. A single candle burned beside his cold, pale, still face. His trembling wife clutched a letter she would not share. The butler claimed he heard nothing unusual during the storm. Yet muddy footprints marked the hallway floor near the library. Sarah noticed a broken pocket watch stopped at three o'clock. Someone had been here, someone who knew the house well. The storm outside mirrored the chaos within these ancient walls. Every guest had a motive, every alibi a hidden crack. Sarah lit her lamp and began her long, careful search. The truth waited patiently in the shadows, ready to emerge.
