Rain hammered the blackened windows of Hollowmere Manor as Detective Mara Voss stepped from her silent car into the storm. A butler with a candle met her at the door and led her through a house too quiet for comfort. The library smelled of cold ash, expensive leather, and the sharp metallic tang of blood freshly spilled on pale carpet. Lord Edric Hollowmere lay beneath his massive oak desk with a silver letter opener buried deep in his own throat. His eyes stared upward at the painted ceiling, and one pale hand still clutched a torn corner of loose paper. Mara knelt beside the body, careful not to disturb the scene, and studied the strange symbol drawn in dark soot. Outside, thunder shook the manor, footsteps echoed above them, and somewhere a clock began striking midnight with terrible, steady precision. Mara looked up, quietly whispered a name unspoken for years, and felt the murderer watching from the cold dark hallway.
