The storm had battered Blackwood Manor all night, and the old house groaned beneath the wind’s relentless, icy, merciless assault. Detective Eleanor Vance arrived at the tall iron gates just after dawn, her boots sinking into the muddy, shadowed driveway. She was met by a pale maid whose trembling hands clutched a fine silver tray of untouched, steaming morning tea. ‘The master is dead,’ the pale maid whispered, her trembling voice barely louder than the cold, dark, distant rain outside. Detective Eleanor Vance stepped into the dark grand hall and saw the body sprawled across the expensive, bloodstained Persian rug. A cruel, jeweled dagger protruded from his still chest, and a single long candle flickered on the dusty marble mantle. No muddy footprints marred the polished wooden floor except for a single set leading straight toward the tall open window. Detective Vance narrowed her sharp eyes, certain that this lonely stormy night held secrets far darker than simple, quiet death.
