# The Blackwood Manor Murder The morning fog crawled slowly through Blackwood Manor as the maid screamed upon finding Lord Harrison dead in his study. Blood stained the antique Persian rug beneath his body, while a mysterious letter lay clutched tightly in his cold hands. Detective Moore arrived promptly, carefully studying the scene with sharp eyes that noticed everything others had simply overlooked in panic. The three suspects stood nervously in the grand foyer, each quietly claiming innocence while exchanging suspicious glances with one another. Outside, rain began falling heavily against the manor's windows as thunder rolled ominously across the darkening sky above the estate.
