"But the skeletons we saw?" questioned Frank.
"A little phosphorus produced them," explained Mrs. Medford. "I drew the skeleton outlines on the sheets with phosphorus. Of course they'll be visible only in the dark."
"Mrs. Medford, you're a wonder!" declared Hodge. "Now we're all right. There'll be ghosts abroad in the Adirondacks to-night."

"Almost wish I had decided to go," confessed Browning. "But I'll stay here and take care of Mrs. Medford."
"If you wish to go, I can take care of her," assured Warren Hatch.
"It's too late now," said Bruce quickly. "Besides that, it's quite a walk over there, and I'd get tired of dancing in short order. I'll stay here and rest."
They paused a moment on the veranda. The night was very still, and the moon was just rising above the treetops, silvering the mirror-like surface of the lake.
From far away on the southern shore came the sound of music and they could see the gleaming lights.
"Take care of those girls, boys," called Mrs. Medford. "If anything happens to them I'll never forgive myself for letting them out of my sight."
