The rain hammered windows of Blackwood Manor while Detective Elena Marsh stared at the body sprawled across the library floor. Blood pooled beneath Lord Ashworth's head, staining the Persian rug crimson, and nobody in the household dared to breathe aloud. She noticed the overturned teacup, the missing letter opener, and the faint smell of almonds lingering in the cold air. Outside, thunder rolled across the moors as the grandfather clock struck midnight and every suspect gathered nervously in the hall. "Someone here is lying," Elena whispered, studying their pale faces, "and I intend to discover exactly who before morning comes." The drawing room door suddenly creaked open, revealing an empty corridor and fresh muddy footprints leading toward the dark garden.
