Rain hammered the seaside manor as detectives gathered for supper. Lightning flashed, briefly illuminating the cliffside drop beyond the terrace. Detective Mara Vance removed her coat, eyes scanning nervous faces. The host, Victor Harrow, raised crystal glass with practiced charm. His smile faltered when thunder drowned the gramophone's scratchy waltz. A servant whispered something urgent; Victor's knuckles whitened around cutlery. Mara followed them through swinging doors into the shadowed kitchen. There, beneath hanging copper pans, the chef lay unnaturally still. Blood trickled across tiles, pooling beneath broken bottle of burgundy. The windows were latched; only one doorway led here tonight. Mara knelt, noticing flour footprints circling, then stopping abruptly short. Behind her, someone softly locked the door, turning key twice.
