“But who could be in there?” Nann wondered. “We have never seen anyone around except the pilot of the airplane and we have all agreed that he can’t be here tonight.”

“No, he isn’t!” Dick was fast recovering his courage. “I believe Dories may have been right Probably it was only reflected moonlight. Perhaps you girls had better remain in the punt while we fellows investigate.”

“No, indeed, we’ll all go together.” Nann settled the matter. “Now shove back up to the mound, Dick, and let’s get out.” This was done and the four young people climbed from the punt and stood for a long silent moment staring at the ruin that loomed so dark and desolate just ahead of them.

“Thar ’tis! Thar’s that light agin!” Gib seized his friend’s arm and pointed, adding with conviction: “Dori was right. It’s suthin’ swingin’ in the wind an’ flashin’ in the moonlight.”

“Gib,” Nann said, “that is probably what the people in Siquaw Center have seen on moonlight nights.”

“Like’s not!” the red-headed lad agreed. Then stealthily they tiptoed toward the two tall pillars that stood like ghostly sentinels in front of the roofless part of the house which had once been the salon.

The side walls were crumbled, but the rear wall stood erect, supporting one side of the roof which tipped forward till it reached the ground, although one corner was upheld by a heap of fallen stone.

“I suppose we’ll have to creep beneath that corner if we want to see what’s under the roof,” Dick said. He looked anxiously at the girls as he spoke, but Nann replied briskly, “Of course we will. Who’ll lead the way?”

“Since I have a flashlight, I will,” the city boy offered. “Here, Nann, give me your lantern and I’ll light it. Then if you girls get separated from us boys, you won’t be in the dark.”

“Goodness, Dick!” Dories shivered. “What in the world is going to separate us? Can’t we keep all close together?”
