chunk: Shortly after, as Somerset and Mills return to the police station, they are approached by a man covered in blood, surrendering himself. Mills recognizes him as Doe and arrests him. They discover Doe has been removing the skin on his fingers to avoid leaving behind prints; the blood on him is from a yet-to-be-identified victim. Doe, through his lawyer, advises there are two more victims and offers to take the detectives to them and confess to all the murders, but only under very specific terms, or he will otherwise plead insanity. Somerset is wary, but Mills agrees.
