Brødrene Dal og mysteriet om Karl XIIs gamasjer

The story

On a dark and stormy night, the Dal Brothers are summoned to the King. He needs their help, for the future of the nation hangs in the balance. In the old 1905 Union Treaty with Sweden, the Swedes slipped in a seemingly insignificant clause: within 100 years, Norway must return King Charles XII’s gaiters, left behind at Fredriksten Fortress when he died there in 1718, or else the dissolution of the Union would be invalid. Now, just before the centenary of that dissolution, it turns out the gaiters were never returned, and, worse still, they’ve vanished without a trace.
