Meanwhile, a local girl goes missing, her apartment staged to mimic Doe’s victims. Mills, increasingly unhinged by the case, accuses Somerset of avoiding closure. The detectives confront their own demons: Mills’ nihilism and Somerset’s isolation. They decipher the next part of the riddle using Doe’s journal— "Inglorious saints decay before the sinner’s dawn." The clock tower yields a hidden room where Doe’s belongings lie, including a tape with a final message: "You sought me as a monster, but I am the mirror. The seventh sin you lack... is faith." Doe, it’s revealed, believed true faith in humanity was the ultimate sin, a flaw in his philosophy. The missing girl is found alive, a trap to lure the detectives into solving the puzzle.
