The rain drummed against the old mansion’s grimy windows tonight. Flickering gaslight cast long shadows across the abandoned hallways. Detective Mara Vey stepped inside, her breath fogging the cold air. A single violin’s mournful note echoed through the empty grand room. Footprints in mud led to the locked study’s heavy oak door. Inside, a body lay sprawled near a shattered decanter of wine. The victim’s fingers clutched a torn page from a yellowed journal. Bloodstains spelled a single word: *"Remember."* Mara’s pulse quickened as the house seemed to exhale a sigh. Something here had waited for her arrival, patient and cruel.
