"Oh, no, not shiftless," put in Mr. Mason. "They are just care-free."

"Humph! All right, then. Care-free. Just too lazy to care for anything at all, if they can get enough to eat, and I suppose that is not hard down here."

"They are quite all right when you get used to them," put in Mrs. Mason.

It was nearing dusk when they at last turned back toward the city, and it was then that Walter reminded Nan of her promise to tell him all about the mysterious men who had startled her so.

Nan obeyed, but, strangely enough, felt none of the uneasiness that she had felt on board the boat and in the hotel. There was something about the luxurious comfort of the car and Walter's reassuring presence that made her feel quite safe.

But Walter himself was anything but calm. He glowered fiercely at the road ahead of them and his hands clenched tightly on the wheel.

"It's a rotten shame!" he burst out, when Nan had finished her story. "If I once get hold of those fellows there won't be enough left of them to identify."

"But you will help me find Mrs. Bragley's property for her, won't you?" insisted Nan. "She said it was at a place called Sunny Slopes."

"Sunny Slopes, Sunny Slopes," Walter repeated thoughtfully. "The name sounds rather familiar to me. I tell you what I'll do," he said, turning to Nan with sudden decision. "Dad knows the names of nearly all the places through here. And if this Sunny Slopes is anywhere near Palm Beach we'll drive over in the car. How does that suit you?"
