Look, I've heard your name around the precinct. I know the circles you travel in. The occult, demonology, exorcisms. Just before my sister was committed, she became deeply paranoid. She started talking about demons, angels. Now, I think someone got to her, Mr. Constantine. I think they brainwashed her into stepping off that roof. Some kind of legion or, um, or cult.
Sounds like a theory, detective. Good luck
