The heavy velvet curtains parted slowly to reveal the silent body lying twisted across the cold and polished marble floor. Sharp shards of broken crystal glittered like scattered diamonds caught beneath the pale glow of the flickering antique wall sconce. No one dared to breathe while the chilling winter draft whistled through the cracked window pane above the grand staircase. Detective Thorne adjusted his damp woolen coat and stared intently at the crimson stain spreading upon the ivory silk rug. He knew that someone in this room held a secret dark enough to justify this brutal and very calculated crime.
