The furious storm raged wildly outside the old mansion now. Inside the grand hall laughter echoed hollowly through the ancient walls. Suddenly everyone froze at the blood-curdling scream heard remarkably clearly. Everyone turned to see the horrifying sight unfolding before them. Blood pooled beneath the lifeless body sprawled across the floor. The hostess clutched her pearls in utter disbelief and shock. Guests whispered frantically among themselves trying to comprehend the scene. Faces drained of color as shock settled over the room. Detective Marlowe pushed through the crowded room swiftly and silently. His sharp eyes scanned the gruesome scene before him methodically.
