30 Chris The police came round again today. Two plain clothes detectives, this time. A senior officer called McKenna — an inspector of some sort — and a bloke called Brennan. They wanted to know about safeguarding measures at the school, what the kids were taught about speaking to strangers and walking home on their own. They said Kai Bolton was meant to be dropped back home by his dad, but for some reason that didn’t happen. The dad’s in pieces, apparently, as I imagine he would be. They wanted to know if I could think of anyone who knew both boys who might be a person of interest. I got agitated and worked up. I couldn’t think of anyone, I said. I desperately wanted to help them, I said, but there was nothing I could do. I told them I’d been racking my brains ever since it had happened
