‘Have we got close-up photographs?’

‘I made sure Cathy uploaded several of each body onto PCloud.’

‘In that case, I’ll pass.’ I shuddered. ‘Bit close to home.’ An image of Sabbir’s remains flashed before my eyes. ‘I’ll call Dr Clark for a verbal.’

Shen was arriving, and I walked over to meet her at the Portakabin.

‘Any developments?’ I asked her.

‘We’ve got some useful leads. The analysts have reported on the eyewitness data, and intelligence is coming in from smartphone users following the social media ping-outs.’ She had really taken to her new role and was shaping up as a valuable team member. She took out her notebook and mentioned several things that confirmed what Dan and I had learnt. ‘Mixed feeling about Simas and Indra . . . everyone says they were polite and hard-working . . . local shopkeepers in competition with each other. And . . . ’

My ears pricked up.

‘. . . several people mentioned that Simas Gudelis had lady visitors when his wife was out.’

This corroborated what Marta, and the shopkeeper, Natassja, had told us. ‘Any descriptions?’

‘A few people mentioned a tall woman with a black bob and a silver BMW. She used to park it round the back of the shop. Someone else mentioned a fair-haired woman with a nose-stud, and pink tufts in her hair.’

‘Did no-one recognise either of them?’ Everyone knew everyone round here. Even if certain groups didn’t actively mix, they still knew what was going on and who everyone was.

Shen shook her head.

‘It’s possible they don’t want to say.’ I was processing the information. ‘Any other eyewitness data?’

‘Two further teenagers mentioned Frazer and LfA. A Somalian boy said that a guy called John had been at his youth club – it’s the one on Shandy Street . . . ’

‘Arbour Youth Centre? I know it. Busy place.’

‘That’s the one. Apparently, this John encouraged lots of the kids there to join the forum. Told them it was a laugh and he’d make it “worth their time” if they came along to protests. And something about masks.’

I felt a flurry of excitement. With so many people mentioning Frazer and John, I sensed we were onto something, along with reports of masks with logos. ‘Sophie Williams has just mentioned a guy called John. He’s a student at New City College. She knows him from their youth club.’

She nodded. ‘No-one seems to know his surname.’

‘I’ll drop in at the Arbour place. Someone has to know where he lives.’ I was thinking aloud. ‘Can you get onto the registry at New City College and ask them for the full names and addresses of all students called John?’ With such a common name, it was going to be like looking for a needle in a haystack, but we had to try.

‘Sure.’
