In a couple of minutes, we were outside Bruce's teacher's flat. She lived in an end tenement block with its construction date chiselled into the sandstone above the door. 1881. It was a nice enough area without being as leafy as the one we'd just left.
"Kiddie fiddler lives a couple of doors down," Erica said. "Real sicko."
"Once they're out, they have to live somewhere," I said.
"He was never locked up. The dirty sod walked."
"Lack of evidence?" I asked.
"Yeah, and he was smart. Wouldn't talk. Right from the off, all he ever said was, 'No comment'."
"You think there's a chance he might have followed Bruce's teacher to school?"
"Now that you mention it." Erica nodded slowly. "Maybe we should pay him a visit."
"Right after we've spoken to Mrs Lennox." I pressed the buzzer and a man's voice answered. "Police," I said. I always enjoyed saying that.
