ll tell you," he said and waggled a finger in front of their faces.
"This is the Headquarters of the German Army Intelligence in the field.
I am taking you before the _Kommandant_. And now we shall learn all
about you two. Yes, you will be very wise to answer truthfully all the
questions _Herr Kommandant_ asks."

With a curt nod to show that he meant what he said the German climbed
down onto the street, and then motioned for Dave and Freddy to climb
down, too.

"That building, there," he said and pointed. "March! And do not be so

The first thing Dave saw as the Lieutenant pushed him through the open
doorway was a desk bigger than any other desk he had ever seen. It was a
good nine feet long and at least five feet wide. It took up almost one
whole side of the room and upon it were piled books, official papers, a
couple of portable short-wave radio sets, and at least a dozen

widened and his jaw dropped in amazement. He got
