However this is England in 1936, a magnet for opposing forces and their first moves in preparation for the coming conflict, assisted or prevented by a royal crisis (depending on which side you're on). Cambridge history professor Tom Wilde may fall into the middle of this accidentally to begin with but his curiosity has been piqued enough to ensure he's not walking away.
