I mis-guessed on the final ghost. It was a Shade, which means Ghost Writing was the final evidence I needed. But the book remained blank. Maybe I needed to move it outside the room? I know Shades can be timid, and the book says they are hard to 'find'.
I still don't know why the sound sensors weren't working. Maybe I placed them too close together, since they aren't directional and detect a radius? I put them back to back because I thought they detected from a direction. Maybe when I see their white outline I'm supposed to hit the trigger button instead of simply dropping them. I'll remember that for next time.
