"Have you learned anything about the German spy plot?" questioned Mary Louise eagerly.
"Not yet. My quest resembles a cart-wheel. I go all around the outer rim first, and mark the spokes when I come to them. Then I follow each spoke toward the center. They'll all converge to the hub, you know, and when I've reached the hub, with all my spokes of knowledge radiating from it, I'm in perfect control of the whole situation."
"Oh. How far are you from the hub, Josie?"
"I'm still marking the spokes, Mary Louise."
"Are there many of them?"
"More than I suspected."
"Well, I realize, dear, that you'll tell me nothing until you are ready to confide in me; but please remember, Josie, how impatient I am and how I long to bring the traitors to justice."
"I won't forget, Mary Louise. We're partners in this case and perhaps I shall ask your help, before long. Some of my spokes may be blinds and until I know something positive there's no use in worrying you with confidences which are merely surmises."
Soon after this conversation Mary Louise found herself, as head of the Liberty Girls, in an embarrassing position. Professor Dyer returned from Chicago on an evening train and early next morning was at the Shop even before its doors were opened, impatiently awaiting the arrival of Mary Louise.
"There has been a mistake," he said to her, hastily, as she smilingly greeted him; "in my absence Mrs. Dyer has thoughtlessly given you some old furniture, which I value highly. It was wife's blunder, of course, but I want back two of the articles and I'm willing to pay your Shop as much for them as you could get elsewhere."
