Dorothy’s expression changed. “I must remind you, Mr. Harding, that I am the head of my department and responsible to the managing editor only. If you desire to detail me to a special assignment you must speak to him first.” There was truth in what she said, and Harding hesitated. Dorothy turned to Mitchell. “Do you wish to see me?”

Mitchell cast an amused glance at the indignant city editor whose florid complexion rivaled his red necktie in point of vivid color, then pulled forward a chair and made himself comfortable. Harding glanced about, and, finding no other chair in the small room, propped himself against the side of the desk and the wall.

“Go ahead, Mitchell,” he said pugnaciously. “Tell her what you told me.”

“Yes. We were both taught wireless at the National Service School, the woman’s preparedness camp at Chevy Chase, Maryland.”

“Have you kept up wireless instruction since then?”
