Lt. George Murray needs his brother Charles' help. One of his fellow officers has not heard from his wife in Edinburgh for several weeks, and he's worried. George would go himself but Charles is only in Fife and besides, George is waiting in Belgium while a small man named Bonaparte, newly back from Elba, decides whether or not to leave Paris and fight. But what Charles Murray finds out in Edinburgh will not be straightforward, and in the end both brothers' lives will be in danger, in more ways than one.
