“It’s good of you to ask me,” the Fairaday girl murmured, “and truly, I would like to accept. Just now I’m afraid I can’t. You see, there’s a special reason why I must stay here—for a few days at least.”

She hesitated and did not explain. Madge looked troubled.

“I’ve written to an aunt in New York and as soon as things are settled I expect to live with her,” Anne went on hurriedly. “I do appreciate your kindness only I know I’ll be safe here. It’s lonely but I’m used to that. The one thing that worries me is what I shall live on after the estate is settled. Father left only this house and a few hundred dollars.”

Madge was startled by this frank disclosure. The shabby appearance of the interior of the house had warned her that the Fairadays were not as wealthy as rumor would have it, but it was difficult to believe that Anne faced poverty.

“Father was never practical about money matters. He built this expensive house and installed a laboratory on the second floor that would do credit to a scientific institution. He spent so much on experimentation too.”

“You must be proud of the name your father made for himself,” Madge said politely.

“Yes, I am, and he was a dear, too. But if only he hadn’t been so careless about details! Several times he made important discoveries, only to let others reap the commercial reward. Before his death he worked out some preparation which when applied to iron and steel prevented rust—several large companies were interested in it too. He promised me faithfully he would register the formula in the patent office.”

“He never did?”

“No, he kept putting it off. He always said the formula wasn’t perfected. He always assured me no one could steal it for he kept the experiments to himself and hid all the data where it would never be found.” Anne laughed shortly. “Well, he did a good job of it! I’ve searched this house high and low and can’t find a trace of it.”

“You’re certain the formula is valuable?”
