The final challenge was announced via a red envelope handed to them by a stoic host in a wool sweater. It read: “Finn din fortid. Bygg din fremtid. Dra til Lofoten og gjenforen familien Sæterbakken.”

“I want to win ,” he said.

A rickety dock emerged from the mist. They tied the boat, ran up a gravel path, and burst into a small village hall in the town of Sortland.

Lena’s eyes widened. “You want to steal a boat?”

Gus didn’t look at the prize. He looked at Astrid. “The boat,” he said. “The red one at the dock. We borrowed it.”

The Alt for Norge crew was there. So were the Olsens—looking miserable, their GPS brick dead, having taken a wrong turn into a tunnel that led nowhere. And there, at a long table set with lefse and brown cheese, sat a family. An old woman with Gus’s exact same ice-blue eyes stood up.

They left the rental car—keys in the ignition, sorry to the next tourist—and scrambled down a muddy embankment. There, tied to a rotting post, was a small, bright red skiff with a 15-horsepower outboard. A handwritten sign in Norwegian said: “Lån meg. Returner meg.” Borrow me. Return me.
