A young medical student becomes embroiled in a longtime mystery, what really happened to Louis Charles, the dauphin to the throne of England. With the help of the first documented police detective, Vidock, they set off on a mission to find out what really happened. The dauphin was kept in the tower and the young medical student's father was his doctor. Everyone was led to believe he died and was buried in an unmarked grave. But is he really dead? And if he isn't, what implications does this have on the throne?
Very fascinating story, well paced, the only disappointment is that there is no real answer to the question. No one will ever know what happened, whether the dauphin survived or not. One of the best historical fiction novels I have read in awhile.
