The rain hammered Inspector Eleanor Voss's umbrella as she ducked beneath the yellow tape surrounding the foggy Whitmore estate garden. Inside the greenhouse, orchids perfumed the humid air, and crimson petals lay scattered around a body sprawled between broken pots. Detective Marcus Hale knelt beside the victim, silently noting the silver letter opener buried deeply within Lord Whitmore's silk waistcoat. 'No fingerprints, no footprints, no witnesses,' muttered Sergeant Priya Nair, photographing the shattered lantern swinging gently above the corpse tonight. Beyond the glass, four guests waited in the library, each clutching brandy, each rehearsing alibis that already sounded suspiciously polished. Eleanor noticed something stranger still: the dead man's pocket watch had stopped at midnight, though nobody heard the clock strike. Then, from the darkness behind the rose trellis, a fifth pair of muddy shoes shifted, revealing someone watching them still. She raised her flashlight slowly, heart pounding, and whispered to Hale that their murderer had never left the garden tonight.
