"Jennings!" she beckoned.
"What is it, Marie?" he replied.
She said nothing, but as he came up the hall led him to the center of the room.
"Listen! I heard sighs and groans!"
Jennings looked at her a moment, puzzled, then laughed. "You girls!" he exclaimed. "I suppose you'll always think the library haunted, now."
"But, Jennings, listen," she persisted.
Jennings did listen. Sure enough, there were sounds, weird, uncanny. He gazed about the room. It was eerie. Then he took a few steps toward the safe. Marie put out her hand to it, and started back.
"Why, that safe is all covered with cold sweat!" she cried with bated breath.
Sure enough the face of the safe was beaded with dampness. Jennings put his hand on it and quickly drew it away, leaving a mark on the dampness.
"Wh-what do you think of that?" he gasped.
