“O.K. I’m ready, Mary Lou. The car is at the door. Run up and get your hat and coat. Wrap up warmly. It’s a lot warmer, and most of the snow’s gone, but you know my runabout isn’t like a heated limousine.”

In five minutes she was back again, looking very pretty in her squirrel coat, with its matching toque. Leaving word for Mrs. Hilliard that she would not be back for supper, she got into the car with Max.

As the couple started, Mary Louise explained why she wanted to go to Center Square: that her project had nothing to do with the thefts at the hotel but was the hope of tracing Margaret Detweiler. And she told her companion the facts she had learned about the girl.

“I’m even more anxious to find her than to solve the mystery at Stoddard House,” she said, “because of those two old people. It’s just too dreadful for them.”

Max nodded. He knew the Detweilers and felt extremely sorry for them. Everybody in Riverside liked them and pitied them in their distress.

“I just can’t bear to tell them that Margaret was dismissed from the department store for stealing,” she added.

“I wouldn’t,” advised Max. “Better tell them nothing at all than that. It wouldn’t help any and would only cause them unhappiness.”

Mary Louise asked about everything that had happened at Riverside since she had left. It had been only two days, but it seemed like an age. Max described the party the night before, but it was a poor affair without Mary Lou, according to his idea, and he had left early so he could get off at daybreak this morning.

The day was clear and warm, and except for the slush on the roads the drive was delightful. The young people were happy to be together again and enjoyed every minute of it.

It was already dusk of the short winter day when they arrived at Center Square and stopped at the country hotel.
