Pity Sir Almsley. He gave his estate to the War Office to help fight the Nazis, not expecting that he would be put in charge of a project to create new espionage techniques. He has no skills in that field, his mission is underfunded, and his staff consists of what the sergeant calls "a human scrap metal drive."
But that's not all. Peter Tilling, an enthusiastic and imaginative child, has been sent to a nearby farm to protect him from the blitz in London. He is eager to slip into Almsley's estate to see the top-secret devices being built there. Good luck with that, young Peter.
Clever soul that you are, you have probably deduced that each of Almsley's problems contains the solution to the other. Right as rain. But it's great fun to watch the story unfold.
