The rain hammered against the windowpanes as Inspector Harlow lit his pipe, its embers glowing faintly in the dim lamplight. Outside, the cobblestone street shimmered with recent downpour, reflecting the eerie glow of a solitary gas lamp flickering weakly. A sharp knock echoed through the study door, startling him from his thoughts, though he had expected no one at this hour. The butler entered silently, his expression grim, holding a silver tray with a single, bloodstained calling card upon it. "Sir," he whispered, voice trembling slightly, "the body in the library was discovered just moments before your arrival, Inspector." Harlow exhaled a slow stream of smoke, his sharp eyes narrowing as he studied the card bearing only a single name: *Eleanor Vexley*.
