Rain hammered the embassy windows while Detective Mara Venn carefully studied the dead ambassador slumped across his polished mahogany desk. A single brass key glinted beside his untouched whiskey, and the locked door offered no obvious signs of forced entry. Mara pulled on thin gloves, noting the ambassador's clenched fist and the faint crimson smear beneath his perfect white cuff. Outside, thunder rolled over the river as her partner, Elias Reed, ducked beneath the police tape with a grim nod. Reed whispered that the ambassador's private secretary had vanished moments before the murder, leaving only a steaming cup of tea. Mara studied the secretary's empty chair, then noticed one fresh muddy footprint leading quietly toward the ambassador's private balcony doors. When she opened those doors, cold air rushed inside and carried the unmistakable metallic scent of fresh blood from outside.
