The heavy mahogany door creaked open, revealing the lifeless body of Arthur Sterling slumped across his polished oak writing desk. A single crimson stain bloomed steadily across his silk shirt while the faint scent of bitter almonds filled the room. Outside, the relentless rain lashed against the tall library windows, masking the sound of footsteps retreating into the dark night. Detective Miller stepped inside, his sharp eyes scanning the chaotic study for any tiny clue left by the elusive killer. He knelt down carefully, noticing a shattered fountain pen lying near the victim’s cold hand amidst a pile of papers.
