Dust motes danced in sunbeams. Lord Ashworth lay quite dead. A silver letter opener protruded. Red stained his velvet smoking jacket. Lady Ashworth entered the the room. Her gasp was chilling loud. She dropped a porcelain teacup. It shattered into many pieces. The delicate floral pattern broke. Lady Ashworth looked quite pale. Her maid, Clara, followed in. Clara saw the dead man. Her eyes went wide with shock. A scream caught in her throat. The air grew stiff with dread.
