Fionn was pensive a moment. ‘The thing with Crombie is that he was hands down the leader.’

‘Was there a need for one?

‘Always.’

‘A bullying cheat? That was everyone’s only option?’

‘Yes. If he hadn’t established hierarchy, he’d have been at the mercy of the other year elevens. He said he could smell the weakness in their piss from a mile away. The only two who had balls were “the alpha bitches”. Violette and – pardon me, sir – your daughter. The rest of us were his minions.’

Yes indeed. Bee came from a long line of alpha bitches on both sides of the tree.

‘You liked being one of his minions?’

Fionn laughed again. ‘It was a strange sort of fun. I’m better as a follower, except I was almost wetting my pants half the time Crombie suggested something to the group. It was mostly getting back at the French kids. The French police captain’s daughter is another one you don’t want to cross. Sometimes it got vicious.’

Fionn looked up at Bish, as if working something out for the first time. ‘Crombie’s a bit bent, you know. He sees things at a tilt. It’s why Violette made sense to him. Everything about her screamed different to the rest of us. Nothing matched. Her accent. Her name. Her face and her hair. She was pretty intense.’ He sighed. ‘It’s hard not to think of her as anything but the Brackenham bomber’s granddaughter, now that I know that.’

‘And the Eddie thing?’

‘I heard someone say his mother died, not even a year ago. But I don’t know, they seemed to just get each other.’

‘Did you feel that she was hiding something?’

‘Weren’t we all?’

Was Bee hiding something, apart from her sorrow? ‘What were you hiding, Fionn?’ Bish asked softly instead.

Another flash of pain in his expression. ‘The girl I’d been hanging out with, we board together at Ashcroft. She came home to Newcastle with me at Easter. My best mate too. It was pretty awful. They hooked up in the end. Came back to school and spread stuff around about my mum. I think I miss being friends with him more than the idea of her, but it was a bad term and I thought the holidays would be even worse, knowing they were together. So the tour made sense.’

Fionn seemed embarrassed by his disclosure. ‘If you tell me that my time will come at university, sir, I’ll have to ask you to leave.’

Bish laughed. ‘I was a social twat at university, so I’d never lull you into a false sense of security.’

Fionn grew pensive again. ‘He’s a smart one, that Crombie. Don’t know why he cheated on that exam. He didn’t have to, you know.’

Was the truth behind the bombing to be found in a hidden part of Fionn’s memory? This boy who noticed the not so obvious? Bish would love to know what he had observed of Bee, but talking about her seemed a betrayal.
