Detective Mara Voss finally arrived at old Blackwood Manor just as the evening fog began swallowing the rusted iron gates. The elderly housekeeper had found Lord Edmund Ashcroft lying face down in his study, a silver letter opener buried deep. Inside the vast manor, cold rain streaked the tall windows while frightened servants huddled together near the marble fireplace, whispering. Nobody had heard anything unusual during the stormy night, yet every single guest at the weekend party had a motive. The heavy study door showed no signs of any forced entry, which meant the killer had been someone trusted completely. Mara crouched quietly beside the body and noticed something glinting beneath the Persian rug, half hidden by the mahogany desk. It was a torn piece of cream stationery bearing only two words written in an elegant, unfamiliar script: "Forgive me." Outside, distant thunder rolled across the moors, and somewhere in the darkness, a door closed with a quiet, deliberate click.
