That's why these rumours ring true for Philippa. Gareth's been acting distant, avoiding her and staying out after school. Until now, she's always put that down to teenage hormones.

Desmond Tinch, Gareth's maths teacher. Tall and thin, with a no-nonsense kind of attitude, but most boys think he's a pretty decent guy. He's been counselling Gareth each week in his office, trying to help this bright boy reach his potential. So he seems like the obvious person for Philippa to call. What would you have said to him, do you think?

I can believe that staff might not have had time to bother with every little rumour circulating round the playground. But this is different. From what Gareth's former classmate Gavin remembers, this is all happening in plain sight. For anyone paying attention, it's obvious.

And anyway, now a concerned parent is asking the school to investigate because she thinks there might be something to the rumours about her son and this teacher. You would imagine this would set off alarms, activating some kind of formal process, you know, internal procedures, that kind of thing.

But Philippa says when she does finally manage to talk to Mr Tinch, he tells her he isn't concerned about Miss Bowen and Gareth. He says there's something else he wants to investigate. What did Mr Tinch tell you? He said, do you think he's on something? Mr Tinch advises Philippa to check whether Gareth's on drugs.

He's just been told a member of staff may be having sex with a child and his response is to bat it back and ask if that child is doing something illegal. But Philippa's desperate to understand what's happening to her son, so she latches on to this. Maybe Mr Tinch is right. Her son's hostile behaviour, the lies, staying out late, these could all be signs he's on drugs.

And she came straight away late on the Friday night. Dr Ferris has her medical bag with her and takes out a syringe.

The medical note Dr Ferris took that night provides one of the only pieces of hard evidence I've seen from the time. It says, in a typical doctor's scrawl, school called mother thought Gareth might be having an affair with female teacher. Now, according to Philippa, it was her that called the school and the doctor got mixed up when she jotted it down in a hurry.

Either way, the crucial thing is, the note suggests the school knew about the allegations. I've tried to put myself in Philippa's shoes. I'd do anything to find out the truth. I'd tell myself I'd have followed my son after school to see what he was doing. But Philippa was a single mum with four kids. She didn't have the luxury of time to spare.

What about calling the police then? Philippa says back when she was breaking up with Gareth's dad and he was drinking lots, he'd hit her. When she ran to the police station to ask for help and told the officer at the front desk what happened... The police said, go home and be a good little wife. This is the late 80s, don't forget, before there are even laws against husbands raping their wives.
