Christmas Operation, or The Incredible Robbery

Every Christmas, an old millionaire performs a strange ritual on his island: he orders toys, gifts, candies, food from the mainland and piles everything under a giant Christmas tree in a half-empty house, then burns it all after the holidays. Why? No one knows, but four children find it too unfair and decide to carry out a robbery. Their carefully planned scheme includes sedating a tiger, breaking into the alarm system, and sliding down the chimney. But soon the kids will have to think only about surviving. Moreover, it seems that the old mansion is inhabited by ghosts. Just what they needed! Get ready for the most incredible adventure, full of dangers, humor, and Christmas spirit! A Norwegian bestseller by the star duo Arne Lindmu and Ida Shelbakken.
