Twenty years ago Garnet Frost escaped London and headed into the desolate Scottish wilderness. Setting off without a map, disaster struck. Garnet found himself trapped between a mountain and the mysterious Loch Arkaig. Lost, cold and alone, he resigned himself to die. But Garnet didn't die. By sheer chance, he was saved by a lone fisherman. For the past two decades, Garnet has been haunted by a memento from his doomed trip. He believes an unusual wooden staff he found while waiting to die is actually a marker for one of history's most famous lost treasures - a spectacular fortune once owned by Bonnie Prince Charlie and lost since 1746. Now, two decades after the trip which almost killed him, Garnet is ready to return to the mysterious loch in his quest to find the gold. What Garnet finds up there, amidst the towering landscape, changes his life forever.
