Rain hammered the cobblestone street as fog curled around the ancient gas lamps. Detective Harris’s leather shoes crunched over broken glass at the estate entrance. The heavy oak door stood slightly ajar, a sliver of golden light cutting the gloom. Inside, the grandfather clock ticked loudly, its pendulum swaying in perfect, eerie silence. A single crimson handprint smeared the polished banister, leading upward toward the master bedroom. The air smelled of ozone and old paper, a strange, metallic tang beneath the perfume. On the writing desk, a half-finished letter lay beside a shattered teacup. The victim, Mrs. Ellingham, was found slumped over at precisely nine fifteen this morning. Her pearls were wound tight around her throat, a glittering, deadly necklace of evidence. Detective Harris knelt, noting the rare orchid crushed beneath the chaise lounge’s velvet leg. A single, unopened envelope lay near her outstretched hand, addressed in a familiar scrawl. He didn’t touch it, instead scanning the room for anything the killer might have missed. The rain outside suddenly stopped, plunging the house into a profound, listening stillness. Only the clock continued its steady rhythm, counting down to a truth no one wanted.
