Where Keith and Stephen live the only signs of World War II are the blackout at night and a single random bomb-site. But the two boys suspect that their neighbors are not what they seem. As Keith authoritatively informs the trusting Stephen, the whole district is riddled with secret passages and underground laboratories — hideaways for any number of murderers, unsung war heroes and secret agents.  Then one day Keith announces that the Germans have infiltrated his own family. And when the secret underground world they have dreamed up emerges from the shadows they find themselves engulfed in mysteries far deeper and more painful than they had bargained for.
