After about half a mile they reach an overgrown turning area. The ground consists of tightly packed stone chips, which is presumably why it hasn’t been completely taken over by the forest. They catch a glimpse of the pool, but the shore is so overgrown that it’s impossible to get an overview. Here and there, between roots and fallen branches, small puddles of rainwater have formed, with pond skaters dancing on the surface. Agnes photographs them while Anna thinks back to the case notes.

She knows that the place where the five friends camped is above the quarry to the left. Eventually she finds an old path. Agnes and Milo follow her, and after a brief tussle with brambles, undergrowth and an increasingly steep climb, they reach an open plateau. This must be the campsite. The view is beautiful – and familiar. The trees are taller, the vegetation denser than in the mural, but there is no mistaking the pool and the steep rocks. Anna is struck by what an incredibly skilled artist Karl-Jo must have been. Not only has he captured every detail and carried off the amazing optical illusion with the surface of the water, but he has also recreated the atmosphere that pervades this place, a kind of melancholy that is reinforced by the fiery yellow dying leaves and the black water. Agnes seems to be aware of it too.

They stand there for a while gazing at the pool. Anna pictures the outline of a body floating just below the dark surface. She can’t explain why, but gradually a new feeling comes over her. The feeling that something other than an accident happened here, something tragic and terrible that cannot be explained by seven yellowing documents in an old file.

When they get back to Tabor, a van is waiting for them. The back doors are open and a small ramp has been lowered. The talkative motorbike dealer is busy wheeling out Agnes’s Vespa, but stops when Milo starts barking at him.

‘There you are,’ Göran says as they come closer. ‘I was starting to wonder if something had happened – we did say I’d deliver today, didn’t we? That’s what I put in the diary.’

He takes a tin of snus out of the pocket of his overalls and tucks a plug beneath his upper lip, then nudges it into the right place with the tip of his tongue.

‘Sorry, my fault,’ Anna says. ‘I’d actually forgotten you were coming today – it’s really kind of you to deliver on a Saturday. Coffee?’

‘Please!’

While she sets the coffee machine going, Göran talks through the Vespa with Agnes. He shows her how to start and stop, and what the various buttons are for. They finish just as the coffee is ready. Agnes puts on her helmet and sets off along the track with Milo trotting along behind, and Göran joins Anna in the kitchen.
