Dave Porter's life has never been ordinary, but the search for his missing father and sister drives him into danger far beyond Oak Hall. From snowy train rides and schoolboy rivalries to the icy North Sea and the streets of London, he meets trouble with courage, honesty, and quick thinking. Along the way, Dave's loyal friends—especially Phil Lawrence, Ben Basswood, and Roger Morr—stand beside him, while old enemies like Nat Poole, Gus Plum, Nick Jasniff, and the blustering Isaac Pludding keep the pressure on. As holiday travel turns chaotic with snow, stranded trains, and comic confrontations, Dave's determination only grows. His quest leads him to England, where clues about Jasniff uncover lies, debts, and a possible link to the Porter family. In a gloomy northern estate, Dave finally learns that his father may be in Christiania, and he sets off for Norway at once. But the journey is far from over: storms, fog, a burst steam-pipe, and Roger's sudden disappearance at sea raise the stakes again in this lively adventure of loyalty, mystery, and hard-won hope.
