‘Why didn’t Alex and Carina sleep in the same tent? They were a couple, weren’t they?’ Anna asks.

Bruno and Marie look at each other. They were not prepared for that question.

‘Their relationship was something of a rollercoaster during the last year of high school,’ Marie says after some hesitation. ‘It ended for good only a month or so later, when Carina left Nedanås. Sorry, Caia.’

‘How did Alex take that?’ Anna asks. Jens raises an eyebrow.

Bruno and Marie look at each other again. ‘Not very well,’ Bruno mumbles.

‘Was that when he ended up in the psychiatric unit?’

The silence is deafening. Both Bruno and Marie shuffle uncomfortably.

‘We don’t know anything about that,’ Marie says. Her voice lets her down, and Anna is in no doubt that this is a lie. She allows the silence to continue for a few seconds, then nods to Jens to indicate that he can continue.

‘How did Simon seem when he went to bed?’

‘Same as usual.’ Marie is trying to keep her mask in place, but the questions about Alex have shaken her. ‘We said goodnight and . . .’ She looks away, bites her upper lip. ‘And . . .’ Her voice breaks.

Bruno gets up, puts his arm around his wife and rests his head on hers in a surprisingly tender gesture. Marie is considerably taller than her husband, and if it weren’t for the sorrow on their faces, the tableau would have looked quite funny.

‘And after that we never saw Simon alive again,’ Bruno says quietly.

‘And neither you nor Alex left your tent?’

He shakes his head. ‘No.’

‘Are you absolutely certain?’

Bruno is clearly irritated. ‘Have you ever slept in a two-man tent?’

Jens nods.

‘Well, then, you know what it’s like. You’re lying right next to each other. There are at least two zips to open and close the flap. It’s impossible to creep out of or into the tent, especially given that the person who’d been out in the rain would be soaking wet. None of us went outside, not me, Alex, Carina or Marie. Simon slipped on the rocks and died while we were all sleeping just a few metres away. How do you think that makes us feel?’ He gently strokes his wife’s back.

Jens nods again, with a glance at Anna. She has no intention of giving up, at least not yet. There is at least one more question that needs an answer.

‘Why didn’t you jump in the water to try and pull Simon out, Bruno? Marie did.’

A flash of anger crosses Bruno’s face. He opens his mouth as if he is about to snap at her, then controls himself.
