The grand old manor slept under a silent, starless night. A chilling wind whispered secrets through the ancient, creaking trees. Inside, opulent rooms held shadows that danced with fear. Then, a piercing shriek shattered the suffocating, velvet quiet. It echoed from the vast, dimly lit library downstairs. Lord Ashworth lay lifeless beside his scattered, dusty books. His eyes stared blankly at the ornate, gilded ceiling. A single, crimson stain bloomed upon his crisp white shirt. Detective Miller arrived, grim-faced, through the ornate, imposing entrance. He surveyed the scene, already sensing a dark, complex puzzle.
