The purpose of the tiles is to block out distractions from outside, but if a suspect wants to think the point is to muffle screams, that's not usually a bad thing. Carmela Aquilina followed me into the room, closing the door firmly behind her. Procedure says at least two cops have to be in there with a suspect. Unlike a lot of procedures, that one makes a certain amount of sense. One-on-one, it was just possible that a suspect could overpower the detective and grab his gun. Then all kinds of bad shit would follow. Since Karl wasn't permitted in the room, I'd asked Aquilina to back me up. Part of that decision stemmed from the fact that she was available, although I knew that a couple of other detectives from the squad were also in the building someplace. But my other reason for asking her was based on her gender. We didn't yet know what scabs on his psyche our commando was trying to scratch with his witchburning, but I thought hatred of women might come into it somewhere.
