The body of the victim lay crumpled on the polished oak floorboards, a single pool of crimson liquid expanding outward. The ornately carved clock on the marble mantelpiece chimed a lonely midnight hour as a chilling draft stirred the curtains. Detective Inspector Helena Voss stepped through the doorway, her sharp eyes scanning the vast, empty, and dimly lit great room. She noticed a single, broken wine glass on the floor, its crimson liquid gleaming like a ruby under the moonlight. A thin, almost invisible thread of silver wire led from the glass to the far corner, catching the faint light.
