Penny and Amy pretended not to hear. They went out the door before the servant could question them further.
Safe on the street, the girls congratulated themselves upon the success of their scheme.
"Mrs. Dillon is almost certain to learn what we did," Amy declared uneasily.
"Oh, she'll hear about it all right when she comes home," Penny agreed, "but she'll have no idea who called."
"The maid may describe us."
"Possibly, but you're safe, for Mrs. Dillon never met you, did she?"
"No, I doubt that I would even recognize the woman if I met her on the street. I've seen her pictures in the paper though."
"Even if Mrs. Dillon suspects that I came to her house she won't be sure I saw the Rembrandt," Penny commented thoughtfully. "She has no suspicion that I know about the picture."
"What will you do now that you know it's a fake?" Amy questioned.
"I haven't decided yet. I'd like to find out where Mrs. Dillon bought the painting—that might give us a clue as to the real thief. But before I question her I think perhaps I should talk the matter over with Father."
