Ticket to Manhattan

It's 1943, and Tommy Mooney is stuck at Warfield Hall with his English guardians, Lord and Lady Sopwith. A winter storm is coming, and so are some of the world's most brilliant physicists, along with a high-ranking American general. Tommy knows this is no ordinary house party, not when some of the guests are from enemy countries. Good thing Tommy's got 20/20 vision and sharp ears. There'll be no shenanigans on his watch.
Not if he can help it-which he might not be able to.
