The rain fell hard against the old mansion's cracked windows. Inspector Grey stepped inside, shaking water from his dark coat. A body lay sprawled across the mahogany dining room table. Blood stained the white tablecloth in an elaborate crimson pattern. The victim's eyes stared blankly at the crystal chandelier above. Grey noticed a broken wine glass near the victim's hand. Someone had smashed it during whatever struggle occurred here tonight. Thunder cracked outside, masking the sound of creaking floorboards upstairs. Grey reached for his pistol, sensing danger lurking very near. The killer was still hiding somewhere within these cold walls.
