She murmured something which the girls did not catch. Crossing the room, she removed the picture from its hook, and carried it from the study. The girls heard her mounting the stairs.

For a moment they were too dumbfounded to speak. Then Madge exclaimed:

“That’s what we get for our ill bred curiosity! We’ve offended her terribly. It must have been her son.”

Cara nodded miserably.

“The only thing we can do is to apologize.”

They spent an unhappy fifteen minutes waiting for Miss Swenster to return. Madge was on the verge of suggesting that it might be better for them to leave, when she appeared. She smiled brightly as if nothing had happened, but they could see she had been crying.

“We’re terribly sorry,” Madge began contritely. “We didn’t mean to be prying. It was simply inexcusable of us to touch the picture.”

“I understand. It was nothing you did that affected me. Please, if you don’t mind, let’s not mention it again.”

Miss Swenster was especially nice to the girls after that but the incident could not be forgotten in an instant. She made no further mention of cleaning the study and Madge and Cara carefully avoided the subject. They could tell that Miss Swenster was still upset. A half hour later they made an excuse for leaving.

“Do come again,” she urged. “I know I’ve been very inhospitable. If you don’t come back I’ll feel that I’ve driven you away.”
