18 Years

The 18 Years associated with the Utmo family is the long, unresolved interval between Odd Utmo’s son vanishing and the present-day investigation. It gives a measure to a disappearance that has never been explained, while the later loss of Karen Utmo extends the mystery from one missing family member to two.

The Son’s Disappearance

Aslak Krongli tells Kaja Solness that Odd’s son disappeared at fifteen, eighteen years before their conversation. A shoe was found beside an avalanche, but when the snow melted, no trace of the boy was discovered. The single surviving object offers a possible link to the mountain, not proof of what happened there.

The circumstances left room for competing explanations. People spoke of a bear, although Krongli understood there had been no bears in the area eighteen years earlier; others suspected Odd himself. Krongli also relays that when Roy Stille visited the household, Odd and Karen said the boy had failed to return from a hunt. The timing was troubling: it was April, not hunting season.

Karen’s Later Disappearance

Karen disappeared the following year. Some locals believed that grief over her son’s loss had overwhelmed her and that she had thrown herself from a cliff. Krongli says he believes both that account and the possibility that the boy died in the avalanche, was buried beneath the snow, and was carried by meltwater into a lake. He presents this as a belief, not a confirmed recovery: neither the son nor Karen has been found.

The sequence matters. The family’s losses were not one simultaneous event but two disappearances separated by about a year, with the second understood by some through the first. The eighteen-year span gives the son’s absence a fixed duration; Karen’s fate remains attached to it through a local explanation shaped by grief and the mountain landscape.

A Mystery Preserved in the Mountains

After the disappearances, Odd remained alone in the mountains. Krongli describes him as living without television or radio and not even reading newspapers. The isolation helps explain why the story survives largely as hearsay: Odd is the only person left who truly knows what happened, and no account from him resolves it.

The passage of eighteen years has not converted rumor into certainty. A shoe, an avalanche, the season in which the boy supposedly went hunting, and the absence of bodies are all that the local stories can set against one another. The interval records how long the question has endured, not how much has been established.

The Interval in Kaja’s Account

Kaja later leaves Harry Hole a joking message about Odd, his son, and the family’s old misfortune, imagining that the son must still be haunting the area after eighteen years. Her call turns the duration into dark humor, but its subject remains the unresolved disappearance Krongli has described. The contrast is sharp: the number can be tossed off as a punchline, while the missing boy and Karen remain absent and unaccounted for.
