The detective stepped inside the darkened corridor, carefully avoiding every broken piece of shattered crystal glass, while lightning flashed outside. Blood stained the silk carpet perfectly, forming a dark pattern near the fireplace while detectives searched the quiet halls tonight. A solitary playing card lay near the shattered window, revealing a torn photograph that proved someone knew the victim personally. The copper pocket watch stopped ticking completely, marking the exact moment life ended before witnesses arrived quietly throughout the house. The grand staircase stood empty, holding cold shadows that fell upon dusty boards slowly as officers checked every room closely. A faint scent of lavender lingered heavily, masking the sharp smell of gunpowder completely while investigators questioned every suspect within.
