The others agreed, knowing that it would be impossible for Paula to act in the play for long without being recognized.

“I suppose it’s not important,” Amy said, “but I can’t help wondering how Dot found out all this in such a short time.”

“She’s a smart gal,” Peggy answered. “She simply took her camera and bought a cheap autograph book and started walking around the streets in the Canyon Road area, pretending to be a movie-fan tourist. She struck up a conversation with a postman, and asked a lot of questions about who lived in the houses around her. Whenever she asked about a famous person’s house, she took a snapshot. When the postman saw she wasn’t going to actually disturb any of the people on his route, he let her walk with him, and he told her a lot about the people who lived in the area. That’s how she found out about Mr. and Mrs. Andrews, and about Paula. And she found out something else, too. Paula is supposed to be in Europe.”

“In Europe?” Greta asked. “How does she know that?”

“From the letters the postman delivers.”

“You’re not making sense. How can he?” Amy complained.

“That’s the peculiar part,” Peggy said, “and it’s what I meant when I said that there would be even more questions to answer. You see, Dot said that the postman told her he delivered letters from Paula, from different parts of Europe.”

“But Paula has been right here all the time!” Amy cried.

Peggy nodded slowly. “She’s been here for about three months that we know of for sure. And the postman said that she wrote to her parents regularly, at least once a week, until recently. He said that it’s been perhaps a month since they’ve had a letter, and that her parents seem pretty worried. Every so often they wait for the mail to come, and they ask him to look again, to be sure that they don’t have a letter from Paula.”

After a moment’s silence, while they all puzzled about the meaning of this latest development, May Berriman spoke decisively. “It seems to me that every minute we waste discussing the possibilities is a minute of uncertainty and unhappiness for this girl’s parents—and for her, too. Peggy, I think you should go right to her this minute and get to the bottom of the affair immediately.”
