Hunt gave a brief nod to Colin’s attempt to undermine everything, as if morbid disbelief was a natural by-product of adolescence, something to be grown out of. Masters and parents used to remind us irritatingly that they too had once been young, and so could speak with authority. It’s just a phase, they would insist. You’ll grow out of it; life will teach you reality and realism. But back then we declined to acknowledge that they had ever been anything like us, and we knew that we grasped life – and truth, and morality, and art – far more clearly than our compromised elders.

‘Finn, you’ve been quiet. You started this ball rolling. You are, as it were, our Serbian gunman.’ Hunt paused to let the allusion take effect. ‘Would you care to give us the benefit of your thoughts?’

‘I don’t know, sir.’

‘What don’t you know?’

‘Well, in one sense, I can’t know what it is that I don’t know. That’s philosophically self-evident.’ He left one of those slight pauses in which we again wondered if he was engaged in subtle mockery or a high seriousness beyond the rest of us. ‘Indeed, isn’t the whole business of ascribing responsibility a kind of cop-out? We want to blame an individual so that everyone else is exculpated. Or we blame a historical process as a way of exonerating individuals. Or it’s all anarchic chaos, with the same consequence. It seems to me that there is – was – a chain of individual responsibilities, all of which were necessary, but not so long a chain that everybody can simply blame everyone else. But of course, my desire to ascribe responsibility might be more a reflection of my own cast of mind than a fair analysis of what happened. That’s one of the central problems of history, isn’t it, sir? The question of subjective versus objective interpretation, the fact that we need to know the history of the historian in order to understand the version that is being put in front of us.’

There was a silence. And no, he wasn’t taking the piss, not in the slightest.
