Rain hammered the dark windows. Midnight hid the silent street. A scream split cold air. Lights flickered inside the mansion. Nobody answered my urgent knock. The heavy door swung open. Blood stained the marble floor. A woman lay beneath shadows. Her eyes stared at nothing. I knelt beside her body. A silver knife gleamed nearby. Footsteps echoed down the hallway. Someone watched from the stairs. I reached for my phone. Then the lights died instantly. Darkness wrapped around the mansion. Someone whispered, “Who killed her?” I drew my heavy revolver.
