Rain hammered the cobblestones as Detective Marlowe entered the dimly lit manor, clutching a crumpled note that hinted at betrayal. The grand staircase spiraled upward, its polished banister reflecting flickering candlelight and whispering secrets of forgotten crimes that haunted everyone. In the library, a shattered vase lay beside a crimson-stained rug, the perfume of lilies masking metallic tang of death. Marlowe's flashlight illuminated a half‑written diary, its pages trembling as if breathing, revealing a name: Evelyn who vanished earlier today.
