Twenty years ago, Garnet Frost escaped London and headed into the desolate Scottish wilderness, where, not having a map, he got lost. Trapped between a mountain and the mysterious Loch Arkaig, cold and alone, he resigned himself to dying. By sheer chance, Garnet was saved by a lone fisherman and for the past two decades, he 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. Now, over two decades later, Garnet is ready to return to the mysterious loch in his quest to find the gold.
