The body was discovered just after midnight in the study. Detective Mara Quinn arrived quickly despite the heavy pouring rain. She noticed the victim clutching a torn letter in death. Outside, reporters gathered silently beneath the flickering streetlights waiting desperately. Inside, Mara worked silently while examining the cold, unmoving corpse. Somewhere upstairs, a floorboard creaked ominously in the nearby darkness.
