“I suppose it is nothing but a joke,” Rosanna acknowledged, “and yet why should a key be enclosed in the letter?”

“It’s beyond me, Rosanna. Even if the trip is wasted, you might feel better about it if you went to Raven Ridge and investigated.”

“I’d go in an instant if I had the money to spare.”

“I’ll loan it to you.”

Rosanna shook her head.

“No, I can’t take it although it’s kind of you to offer.”

“I wish I could help you, Rosanna.”

“You’ve helped me a great deal already. Perhaps a little later on I’ll find some way of getting to Raven Ridge.”

Penny tried to urge the loan, but Rosanna, who was unusually proud, would not hear of it. The girls parted at the latter’s boarding house on Sixty-fifth Street.

“I’ll see you within a day or two,” Penny promised as she drove away. “Perhaps by that time Father will learn something about Mr. Elfhedge.”
