Relentless rain lashed against the tall, grim windows of Blackwood Manor, mirroring the violent storm that was brewing deep inside. Inside the cavernous study, Inspector Davies stared down at the lifeless body, his face pale and drawn with grim shock. Lord Ashworth lay sprawled across his massive oak desk, a silver letter opener buried deep within his broad, pale chest. A single white rose rested upon his frozen lapel, a delicate touch that seemed entirely out of place amidst violence. Outside, the wind howled like a hungry wolf, rattling the heavy doors as if demanding entry to the macabre scene. Davies noticed the fireplace held warm ashes, suggesting someone had been here recently, perhaps just moments before he had arrived. He turned slowly, scanning the shadowed corners of the room, feeling absolutely certain that the killer was still lurking nearby.
