Jessica took her identification out from her jacket pocket and let him examine it. He held it close to his face and, for a moment, she thought he was going to lick it. Much to her relief, he didn’t and handed it back. ‘C-C-Come in.’

As much as you were trained to treat and judge people on their actions and words, police officers were still human beings and made snap first impressions like anyone else.

The front door opened immediately into a living room and, as Jessica sat in the armchair the man offered to her, she could see why the team had picked on him. She remembered being at schools and in clubs herself and knew there was always one teacher or helper who the children targeted. For her there was the geography teacher who would stand and wait for the class to go quiet but, when she was younger than that, she remembered a form tutor dashing out of registration in tears because no one was listening to her.

Michael stood in front of her rocking slightly from one leg to the other. ‘Can I get you a cup of tea or something?’

‘If it’s not too much trouble, that would be fab. No sugar though, just milk.’

Jessica didn’t really want one but figured if he was in the kitchen, she could have a proper look around his living room. It was a trick one of the men she first worked with had taught her. He had told her off for turning down a hot drink and then, when she’d told the person she’d changed her mind, they had scuttled off and her colleague had proceeded to look at every photo, even opening a few drawers.

With Michael out of the room, Jessica stood and peered at a couple of pictures around the room. Nothing appeared to be recent. A couple of photos seemed to be of a group of people who looked like teachers. Jessica could clearly see Michael standing on the end, leaning slightly to one side. There were two even older photos of a couple getting married whom she assumed were the man’s parents. The only picture that jumped out was on the mantelpiece behind another frame. She had to pick it up to see it properly but it was of a rugby team. She looked to see if either Ed Marks or Lewis Barnes was a part of the side but it didn’t look like it. Jessica put the frame back down and returned to the armchair.

The whole room looked like a throwback to twenty years ago. The carpet, sofa and armchair all had flowery patterns, the wallpaper sporting an awful raised print design. It had been painted over and was flaking in some parts. When she looked properly, Jessica could see the windows were single-glazed too with flimsy looking wooden frames. It was the kind of house she had grown up in but even her parents had redecorated at least twice since.

Michael walked back into the room with two china teacups clinking on saucers next to a teapot on a tray. It didn’t surprise her to see the crockery had a flowery pattern too. He put everything on the coffee table and sat on the sofa. ‘I hope I didn’t put t-t-too much milk in.’

Jessica took a sip just to be polite and assured him it was fine. ‘Thanks for inviting me around, Mr Wright. I just wanted to ask you a couple of questions about some of your former students, if that’s all right?’

‘I’ve not taught for over ten years I’m afraid, I’m not sure h-h-how much use I can be.’ He pushed his glasses up higher on his face but seemed far too nervous to actually look at Jessica.

‘If I ask you about a couple of people, could you tell me if you recognise the names?’

He made something approaching a gurgling noise before saying that was fine.

‘Do you remember a student called Edward Marks?’

The man’s reply was instant. ‘Yes, he took A-levels in English Literature, Communication Studies and Art. He had a brother called Charles.’

Jessica was a little startled. ‘How do you know that?’

‘If I’ve taught someone, I remember everything. Edward got two C’s and an A for Art if I remember correctly. He played hockey and rugby too. He was a pretty quick winger from what I remember.’

Jessica noticed his stammer had gone and he suddenly sounded confident. ‘How about Lewis Barnes?’

‘English Literature, History and Geography. Two B’s and a C. He also played rugby, open-side flanker, and was a keen swimmer.’

‘Jacob Chrisp?’

‘Government and Politics, History and Communication Studies. B, C, D. Inside centre.’

Jessica tried to remember one of the other names from the photo. Izzy had matched as many first names to surnames as she could and they had identified all but three of the players, although hadn’t contacted anyone except for Jacob.

‘How about Rory King?’

‘No idea, not one of mine.’

‘Timothy Davidson?’

The man shook his head emphatically. ‘Nope.’

Jessica gave him a few more names; some of them he knew, some he didn’t. ‘I’ve got to ask again, how can you remember all this? It’s astonishing.’

The man sounded nervous but somewhat proud. He had stopped stammering. ‘It’s just something I can do. If I’ve taught or coached someone, I remember things like that. Those names weren’t too long from before I retired but I can go back a lot further.’

It almost sounded like a challenge. If he was involved in any way, surely showing off this kind of knowledge of the victims would be an odd thing to do in front of a police officer? Looking at him, she felt guilty herself for thinking he was a bit odd but he didn’t seem capable of hacking off a hand. Her instincts were telling her he was just someone who had been caught up in something unsavoury a few years ago but was harmless enough.

‘I understand you were a teacher and rugby coach?’ Jessica asked.

‘And hockey – plus I worked for the scouts for a while too.’

‘Why did you stop?’

The man leant forward and picked up the teacup, taking two large sips and then returning it to the tray. His hand was shaking and the hot liquid spilled on his hand. He barely reacted, wiping it on the sofa. Still staring at the carpet he finally spoke. ‘After I got out of hospital I couldn’t face it any longer.’

Jessica suddenly felt awful; there was such pain in the man’s voice. She didn’t want to ask the question but the words came out anyway. ‘Why were you in hospital?’

Michael drank some more tea before answering. ‘An acc-acc-accident with some of the rugby players I was coaching. It wasn’t the first time and things weren’t right at the college either. They offered me some m-m-money to go and I took it and quit everything else too.’

Jessica didn’t know what else she could get from the conversation. The man’s stutter had returned and he was clearly upset. The picture seemed pretty clear without him filling in the gaps. Given years of bullying from the very people he had spent a career trying to help, he had finally reached the end of his tether.

‘I’ve just got one last thing. Do you ever see your students out and about?’ It wasn’t the exact question she should have asked but she didn’t want to upset him further.

‘One of them was my postman for a little while b-b-but unless they’re on TV or in the paper, I wouldn’t really notice. I d-d-don’t often go out.’

Jessica could have continued to talk to him but, despite his almost autistic knowledge of former students, he seemed a little pathetic. As he stood to show Jessica out, a thought occurred to her. Ever since they had looked at the first CCTV footage, they had been assuming the figure in the black cape was a woman. She didn’t think the former teacher was involved but perhaps another male with his stature could be. If they were confident enough to walk in heels, she thought someone as short and slight as him could just about pass as female.

After saying her goodbyes, Jessica drove back to the station. Clouds had started to form and taken the edge off the heat. She walked through reception into her office which was hot and empty. Jessica was planning on running a few more checks on the former teacher. She suspected he may have had a breakdown at some point and, though the police didn’t have open access to someone’s medical records, there could be something in their system that could reveal more about him.
