Rain lashed the cobblestones outside Bellwood Manor as the clock struck midnight. A scream, muffled by velvet curtains, echoed through the grand, shadowed foyer. Detective Aris Thorne, arriving moments later, noted the study door stood ajar. Inside, the venerable Lord Bellwood lay slumped, a letter opener in his chest. His pocket watch, shattered on the Persian rug, still read twelve-oh-five. A single, pristine cufflink glinted near the corpseās outstretched, trembling hand. The widow, clad in mourning black, offered tea with a steady, calm gaze. Thorne observed her eyes, dry and sharp, searching for a hidden, telling truth. Beyond the window, two figures fled, their silhouettes merging with the driving rain. The murder, clearly, was a performance meticulously staged, an intimate, deadly affair.
