I enlisted Saul’s help, she continued. I had to trust someone, and he was far more able than me to see if there was any, what’s it called … She waved a hand around before fingerspelling the word she was looking for, metadata, that’s what it’s called. Something to help us track down who had planted the camera, and who had emailed Bradley and Courtney to get them to meet there in the first place. I also asked Saul to check for any videos having been uploaded to the internet from any school accounts. I wanted to make sure there weren’t any other copies.

Did he find anything? I asked, tense with anticipation.

Jane shrugged. I don’t think he had a chance to get started before someone went to the governors and I was hauled in for covering up a major safeguarding issue. She came back to her chair and sat down with a sigh. Both the students were under sixteen, and that was their main concern, rather than the fact someone had filmed them on school equipment without their consent, and for who knows what purpose. She flung her hands up as she finished speaking, as if to show the futility of what she had been trying to do.

I was naive, she continued. I thought that I had dealt with the incident in the best way for the students concerned – they were stupid, and whilst they weren’t sixteen they both knew damn well what they were doing, I can tell you. It was the person who filmed them that I was concerned about, but the governors insisted they must have done it themselves. Jane gave us an agonised look. They thought I should have punished them, when they were doing what horny hormonal teenagers have been doing since time began. Really, what would that have achieved?

I had to be honest, she had a point. The idea that someone was sneaking around a school and filming students in compromising positions was horrific, and I understood why she’d wanted to try and track down the culprit on the quiet rather than reprimand Bradley and Courtney.

My mind was whirring, and I could tell that Anna’s was, too. Was there any connection between this and what happened to Leon? Could Leon have been the person who filmed Bradley and Courtney, and if he was, what would they have done if they found out? We hadn’t got to the bottom of the animosity between Bradley and Leon, and this could have been the cause.

So, nobody has told the police about this? Jane asked.

No, this is the first I’ve heard of any of it, I told her, shaking my head.
