Even as she thought this, the girl on the cot next to her own half rose to whisper: “We’re Mrs. Hobby’s horses now.” “That’s the girl called Betty,” Norma thought as she barely suppressed a disturbing laugh. “Shish,” she managed to whisper. Then all was silent where, row on row, fifty girls were sleeping. Fifty! And Norma had spoken to barely half a dozen of them! It was all very strange. Strange and exciting.

The story dealt with a stranger in an American uniform who, claiming to be lost from his outfit, had found refuge in their billet for the night. “That night,” her father had said, “flashes of light were noticed at the window of our attic lodging.
