Rain battered the windows as Inspector Blackwell knelt beside the lifeless body sprawled across the cold marble floor below him. Blood had pooled beneath the victim's head, creating a crimson halo that starkly contrasted with her unnaturally pale skin tone. The detective noticed a partially consumed wine glass on the mahogany table beside an unsigned farewell letter near the body. "She was poisoned before being struck," murmured the coroner, pointing toward dark stains upon the expensive Persian carpet below her. Suspicious eyes shifted toward the nervous mansion residents gathered in the adjacent room awaiting their inevitable interrogation by the police. A shattered family heirloom lay near the fireplace, its fragments scattered like secrets across the dimly lit crime scene tonight.
