Rain slicked the cobblestones outside The Blue Canary Jazz Club, where Detective Aris Thorne found his first body. The victim was a celebrated pianist, known for melancholy melodies, now slumped over his own grand piano in death. Thorne noted the single, precise gunshot wound, the absence of struggle, and the cryptic, crimson note clutched in the cold hand. The message read only: "The melody was stolen. The silence begins now." His gaze lifted from the corpse to the club's lone, terrified witness: the singer, her microphone still humming a faint, unresolved chord.
