Murder’s icy stamp first marked the oak dining room table when the candelabra’s final flickering flame sputtered out that evening. Eight stranded dinner guests froze, their wineglasses hovering halfway between lace tablecloths and their trembling fearful parted unspeaking cold lips. Someone fumbled for a flashlight, another struck a match to find their host stabbed deep through his tailored wool suit. The antique letter opener that killed him bore nothing but smudged wiped half-faded fingerprints, no clear trace of the killer. The young nanny claimed she stayed locked in her third-floor room all evening, yet her boots dripped cold garden mud. The host’s estranged brother checked his watch repeatedly, even after all cell signals vanished hours before we found his body. No one dared admit they’d heard the host argue loudly with a mysterious stranger just before dinner that frigid night. Wind howled through the manor’s cracked stone walls, sealing every guest inside with a killer who lurked unseen among them.
