Rain lashed against the ancient windows of Blackwood Manor, creating an unsettling, mournful atmosphere that evening. Detective Inspector Davies arrived, pulling his trench coat tighter against the biting November wind and sleet. The local constabulary had already secured the perimeter, a grim and subdued scene immediately apparent to him. A frantic housekeeper, Mrs. Higgins, detailed the shocking discovery found within the library’s darkened confines. Lord Blackwood lay sprawled upon the Persian rug, a single crimson stain blossoming beneath his chest. Preliminary examination revealed a silver letter opener, gleaming ominously amidst the scattered books and papers. The room itself was meticulously arranged, devoid of obvious signs of a violent struggle or hasty entry. A priceless collection of first editions remained untouched, suggesting a calculated, deliberate act of malice. Detective Davies surveyed the opulent space, noting the chilling stillness permeating every shadowed corner now.
